Does delta airlines accept boxes on checked luggage

Key limits: standard piece must not exceed 62 linear inches (length + width + height = 158 cm). Weight limit for a single piece in economy is 50 lb (23 kg) before an overweight charge; pieces between 51–70 lb (23–32 kg) incur an over‑weight fee, and items over 70 lb (32 kg) typically cannot be processed as regular hold pieces. Domestic first/second bag fees commonly run around $30/$40 per piece on many fares; surcharges for oversize and overweight are extra and vary by route and ticket class.

Packing and protection: use a strong corrugated carton or a hard‑sided container, reinforce seams and corners with heavy tape, wrap fragile items in bubble wrap or foam, and immobilize contents to prevent movement. Remove previous shipping labels, attach a clear name/address tag, and photograph the packed item before check‑in. A visible fragile sticker helps, but does not guarantee special handling.

Restricted items and batteries: spare lithium batteries and battery packs are not permitted in the aircraft hold and must travel in the cabin or be shipped by an approved courier. Other hazardous goods (sprays, large quantities of flammable liquids, certain chemicals) are prohibited from hold transport. Firearms require a locked hard case, must be declared at check‑in, and ammunition has specific packaging rules; failure to follow those rules will result in refusal.

Practical recommendations before travel: weigh and measure the carton at home; confirm piece and weight allowances for your specific itinerary and fare class on the carrier’s website or your reservation; plan for possible fees; arrive early to allow time for special handling requests. If the cargo is heavy, fragile or valuable, compare commercial freight or courier rates – those services often provide tracking and insurance options more suitable than transporting high‑value items as hold pieces.

At the airport: present the carton at curbside or ticket counter for measurement by staff, declare restricted contents if applicable, request a fragile tag if desired, and keep receipts and photographs for insurance claims in case of damage or loss.

Transporting a carton in the aircraft hold – direct recommendation

Transport a carton in the aircraft hold only when each piece conforms to the carrier’s standard piece limit: keep weight at or below 50 lb (23 kg) and linear dimensions at or below 62 in (157 cm) to avoid overweight or oversize surcharges and possible refusal at check-in.

Weight, size and routing specifics

Most economy fares follow the 50 lb / 23 kg and 62 in / 157 cm linear rule; premium cabins or international fares may allow different weight or piece-allowances – confirm for your ticket. If a carton exceeds 50 lb or 62 in, expect an overweight or oversize fee and potential handling restrictions. For extremely large/heavy cartons (approaching or over 100 lb / 45 kg or >115 in linear) arrange freight or cargo service rather than placing the item in the aircraft hold.

Packing, restricted items and on-site actions

Use a rigid plastic container or double-boxed, reinforced cardboard with internal padding; secure seams with heavy-duty tape and protect corners with edge protectors. Label the outside and include contact details and a contents list inside. Do not place loose lithium batteries, flammable liquids, aerosols, or other prohibited items in the carton – loose lithium cells must travel in the cabin only; firearms and ammunition require advance declaration and a locked hard case per airline and TSA rules. At check-in, request a tag and photograph the packed item and its weight for your records. If the carton is likely to exceed allowance or contains valuable/fragile goods, arrange cargo shipment or purchase additional piece allowance in advance to avoid high fees or denial at the counter.

Size and weight limits for cartons routed to the aircraft hold

Keep each carton at or below 62 linear inches (158 cm; length + width + height) and 50 lb (23 kg) to meet the carrier’s standard hold-baggage allowance.

Weight tiers and handling rules:

– 51–70 lb (23–32 kg): permitted but assessed an overweight charge at the airport; verify allowance for your fare class or cabin.

– Over 70 lb (>32 kg): not accepted as regular hold freight and must be transported via cargo/freight services instead of being stowed with passenger baggage.

Dimension tiers and handling rules:

– >62 linear inches (158 cm): classified as oversize and will incur an oversize fee; subject to aircraft space and gate-agent approval.

– Very large items (commonly above 115 linear inches / ~292 cm): typically cannot be processed through passenger baggage systems and require cargo booking.

How to measure and prepare:

– Measure length + width + height including wheels, handles and external pockets; round up to the nearest inch or centimeter.

– Distribute heavy contents across multiple cartons to avoid overweight surcharges and reduce damage risk.

– Reinforce seams, use high-quality packing tape, and pad fragile items; mark cartons with recipient contact and a contents summary for faster processing at check-in.

Always weigh and measure cartons before travel, declare oversized or heavy items at check-in, and confirm any route- or fare-specific exceptions with the carrier prior to departure.

Packing, taping and material recommendations for cartons in the aircraft hold

Use double‑wall corrugated cartons rated ECT‑32 (minimum) or 200+ lb burst strength and seal seams with 3‑inch water‑activated (gummed) tape applied in an H pattern over all openings.

• Outer container: choose corrugated cartons with full overlap flaps; avoid single‑wall or reused damaged cartons.
• Sealing system: 3‑inch gummed tape for primary seams; add 3‑inch polyester filament tape across seams for tensile reinforcement (minimum 375 N/25 mm).
• Strapping: apply polypropylene or polyester strapping (12–19 mm wide) with at least two parallel straps around the length and two around the width for heavy contents; tension and lock with metal seals or buckles.
• Corner and edge protection: install 3–5 mm thick cardboard or plastic edge protectors under straps to prevent strap cutting and corner crushing.
• Waterproofing: wrap the carton in two layers of 50–70 micron shrink film or use a polyethylene outer bag when transporting moisture‑sensitive items.
• Tamper evidence: apply serial‑numbered cable seals or tamper‑evident tape across one flap; place a visible packing list in a sealed pouch inside and a duplicate under a clear sleeve outside.

Internal cushioning and item restraint:

• Layering: provide 50–75 mm (2–3 in) of foam, bubble wrap (min. 3/16″ bubbles), or foam‑in‑place around each item; small fragile pieces require 100 mm (4 in) of protection.
• Void fill: use kraft paper or biodegradable foam peanuts to prevent movement; compressible filler should fully eliminate rattle without distorting the carton.
• Individual wrapping: wrap electronics and glassware in antistatic bubble and seal in a waterproof poly bag; tape loose components to the main item or place in padded compartments.
• Weight distribution: place heavier items on the bottom, distribute mass centrally, and avoid point loads on corners; ensure the container maintains a rectangular profile under normal handling.
• Compression allowance: do not overfill; leave 10–20 mm (0.4–0.8 in) of internal clearance from the lid to allow tape adhesion and prevent bulging.

Tape application technique and finishing:

1. H‑seal method: run tape along the central seam and two perpendicular strips over the flap edges, overlapping by at least 50 mm (2 in).
2. Overlap and layers: apply two complete tape layers across high‑stress seams and three passes of filament tape across long seams for bulky loads.
3. Avoid household tapes: do not rely on masking, cellophane or standard duct tape as the primary seal; use gummed tape for long‑term cohesion.
4. Labeling: attach a waterproof ID sleeve with name, phone, destination and an internal duplicate; mark orientation arrows and apply a bold “FRAGILE” decal for fragile contents (handling not guaranteed by carriers).

Final checks before drop‑off:

• Perform a 30 cm (12 in) drop test from table height onto a protected surface to confirm internal restraint.
• Verify straps and seals remain tight after a 10 cm compression and 90° rotation test.
• Confirm external labeling is legible and barcode/ID tags are not obstructed by tape or strapping.
• If transporting high‑value or fragile items, consider a rigid plastic crate or palletization and add insurance documentation inside the sealed pouch.

Prohibited and restricted items you cannot place in hold containers

Do not place spare lithium-ion or lithium-metal batteries inside stowed containers; carry them in the cabin only and protect terminals (tape exposed contacts or use original packaging).

Batteries, power banks and electronic devices

Portable power banks/loose batteries: Forbidden in the aircraft hold. Power banks and spare lithium batteries must travel in the passenger cabin. Battery rating rules: cells rated ≤100 Wh are permitted in carry-on without approval; cells >100 Wh and ≤160 Wh require carrier approval; cells >160 Wh are prohibited from both cabin and hold. Secure each cell against short circuit (tape terminals, place each in separate plastic bags or original boxes).

Devices with installed batteries: Devices with batteries installed (laptops, cameras, phones) are preferred in hand-carried bags. If a device must be stowed, switch it off and protect against accidental activation. E-cigarettes and vaporizers are never allowed in the aircraft hold and must remain in the cabin.

Explosives, flammables, chemicals, weapons and other hazards

Explosives and fireworks: Consumer fireworks, flares, detonators and similar explosives are strictly prohibited from both cabin and hold.

Flammable liquids and aerosols: Gasoline, lighter fluid, paint thinners, many spray paints and solvent-based adhesives are forbidden. Small toiletry aerosols under 0.5 kg for personal use may be allowed in carry-on but are not for the hold unless specifically authorized.

Compressed gases and fuels: Propane, butane, camping fuel, oxygen cylinders and other pressurized containers are not allowed without explicit carrier approval and proper certification; most are banned from hold transport.

Corrosives and toxic substances: Acids, bleach, pool chemicals, sulfur, oxidizers, and infectious materials (biohazards) cannot be stowed in the aircraft hold.

Radioactive and magnetic materials: Radioactive sources, strong magnets, and other items that interfere with aircraft systems are prohibited.

Firearms and ammunition: Firearms may be transported only when unloaded, locked in a hard-sided, locked container designed for firearms and declared at the ticket counter; follow the carrier’s check-in procedure. Ammunition must be in secure, original or specifically designed packaging; quantity limits and declaration requirements are set by the carrier–verify before travel.

Alcoholic beverages: Alcoholic beverages containing 24%–70% alcohol by volume are limited to 5 L (1.3 gal) per passenger in unopened retail packaging; beverages <24% ABV have no specific volume limit for stowage but remain subject to local laws and carrier rules.

Dry ice (solid CO2): Up to 5.5 lb (2.5 kg) of dry ice is generally permitted per passenger in the hold for cooling perishables if properly packaged, ventilated and declared at check-in; labels and carrier notification are required.

Verify the Transportation Security Administration rules and the specific carrier’s prohibited and restricted list before travel; declare weapons, dry ice, ammunition and other restricted goods at check-in and follow the carrier’s documentation and packing instructions.

Baggage fees, oversized charges and when a box counts as special baggage

Prepay fees and confirm piece allowance for your itinerary; measure (L+W+H) and weigh each packaged carton before arriving at the airport to avoid surprise surcharges.

• Typical U.S. domestic fares (example amounts)
  • First standard piece: $30
  • Second standard piece: $40
  • Overweight surcharges: 51–70 lb (23–32 kg) = $100; 71–100 lb (32–45 kg) = $200
  • Oversize surcharge (linear dimensions >62 in / >158 cm): $200
• International routing and fare-class notes
  • Many transatlantic/transpacific tickets include one or two free pieces (commonly up to 23 kg / 50 lb or, for some classes, 32 kg / 70 lb). Where allowances are not included, excess-piece and overweight/oversize fees usually run from roughly $150 up to several hundred dollars depending on route and fare.
  • Premium cabins and elite-status travelers frequently receive at least one free piece; verify the allowance printed on your ticket or in your reservation.
• When a packaged carton is treated as special baggage
  • A carton exceeding standard piece limits (weight >50 lb / 23 kg or linear size >62 in / 158 cm) will trigger overweight/oversize surcharges and often special handling designation.
  • Items heavier than 100 lb (45 kg) or with linear dimensions beyond ~115 in (292 cm) are normally ineligible for regular handling and must move via freight/cargo or a dedicated oversized-item service.
  • Irregular-shape parcels, fragile crates, wooden crates, and items requiring palletization are commonly processed as special baggage and may require advance notice, reservation, and additional fees.
  • Certain sporting or hobby items boxed for transport (bicycles, surfboards, skis) are subject to their own fee structure and handling rules; declare them at booking or before check-in to confirm charges and space availability.
• Practical steps to reduce fees and handling issues
  1. Measure and weigh each parcel; compare against the allowance shown on your itinerary.
  2. If a parcel exceeds standard limits, evaluate shipping via freight or a parcel carrier – sometimes cheaper than multiple surcharges.
  3. Reserve space for large/special items (bikes, musical instruments, oversized crates) ahead of travel; some items require advance booking.
  4. Label clearly (name, phone, destination) and keep valuables/required documents with you; special-handling items may be routed differently.

Fee amounts and thresholds vary by route and fare class; consult the carrier’s route-specific baggage page or call customer service for exact charges before departure.

Labeling, documentation and how to declare a carton at check‑in

Place a waterproof exterior tag with: full name, mobile number, destination city and final address, flight number or reservation code, and a duplicate inside a clear plastic pouch; secure the tag with a metal or plastic strap and cover with clear packing tape.

At the ticket counter or bag‑drop for hold stowage, announce to the agent that you are handing over a rigid carton and present: a printed itemized inventory, proof of purchase or invoice for high‑value goods, government ID, and a pre‑weigh receipt from a certified scale (if available). Ask the agent to note any special‑handling code on the carrier tag and to provide a stapled copy of the baggage tag receipt.

Affix orientation and content‑warning labels as needed: “This Side Up,” “Fragile,” “Contains Batteries,” or “Perishable.” For lithium cells/power banks remove and carry them in the cabin where allowed; if batteries remain installed, declare them and show manufacturer guidance to the agent – many operators require special handling or forbid stowage in the hold.

For international travel, prepare a commercial invoice or packing list for customs and complete arrival declaration forms; place one copy inside the carton and one with the claim tag. If value exceeds the duty‑free threshold, have receipts and contact details readily available to speed inspection.

Photograph the packed carton from all sides and document contents with a dated inventory; provide a printed copy to the agent and keep digital copies on your phone. If the agent requests additional paperwork (air waybill, oversized handling form), sign and retain the paperwork reference number shown on the tag.

If the carton exceeds published maximums for weight or linear dimensions at the counter, it may be processed as oversized or cargo only; request immediate confirmation whether additional fees apply and whether the item can remain with passenger hold items or must move to the cargo desk.

For high‑value, fragile, or temperature‑sensitive shipments consider booking as cargo instead of standard hold stowage and purchase declared value or third‑party insurance; obtain an air waybill and a cargo receipt. For pet supplies or related guidance see best activity for a pregnant dog.

If an item contains restricted materials (chemicals, aerosol, flammable adhesives, large quantities of liquid, or firearms), consult the carrier’s dangerous‑goods policy at the desk; declare such contents explicitly and follow the agent’s instructions to avoid refusal or fines.

How to file a claim and minimize damage or loss for packaged hold baggage

Inspect the package in the baggage claim area and file a Property Irregularity Report (PIR) with the carrier before leaving the terminal if any exterior damage, seal break or missing contents is found.

Actions to take immediately at arrival

1) Photograph the outer container, all sides of the tag, the baggage receipt stub, and the damaged contents with timestamps or a phone camera that records metadata. 2) Keep all original packaging materials, tape pieces and cushioning; do not discard the damaged box or carry-on used to protect items. 3) Obtain a written PIR (or written incident report) from the carrier’s baggage office that includes the PIR number, agent name, flight number, tag number and a brief description of damage or missing items. 4) If damage prevents safe transport of contents, refuse to accept the parcel and get a written statement describing refusal.

Documentation and claim submission

Compile a single packet for the claim: PIR number, boarding pass, baggage tag, high-resolution photos, original purchase receipts or invoices, serial numbers, and repair or replacement cost estimates. Upload everything to the carrier’s online claim portal and retain the claim reference number and any confirmation emails.

If the carrier’s desk is closed, file the online incident report immediately and follow up with the airport office next business day. Many operators require on-site reporting for visible damage; if you discovered problems after leaving, submit the full claim as soon as possible and check that submission meets the carrier’s stated deadlines (policies commonly set short windows for damage claims and longer windows for delayed items).

When requesting compensation, provide two remedies: a specific repair estimate from a qualified shop and an itemized replacement request (price, model, invoice). Offer both options in the claim form to speed resolution: repair first, reimbursement if repair is not feasible.

Preserve the damaged item for inspection until the claim is closed; carriers often request return inspection or photographs of the repair work. Keep all emailed correspondence and make notes of phone calls (date, time, name of representative, summary).

If contents were high-value electronics, jewelry or specialized equipment, check whether the purchase card, travel insurance or a home policy provides higher coverage than the carrier. Submit secondary insurer claims only after obtaining the carrier’s final determination and copies of its claim decision and payout documents.

Escalation procedure: if no substantive response within 30 days of claim submission, send a certified letter to the carrier’s baggage claims department with all documentation and request an update. For international itineraries, keep records compliant with international conventions and consider contacting the regulatory body or a consumer protection agency if resolution stalls.

For fragile child items or gear frequently exposed to rough surfaces, consider alternatives that reduce claim exposure such as a reinforced backpack (example: best backpack diaper bag for toddler and newborn) or a hard-sided roller designed for uneven streets (example: best luggage for european cobble stone) to lessen the chance of future damage and simplify any required claims process.
