Can you take a backpack and a carry on luggage

Recommendation: Measure both pieces before arrival; typical personal pack limits sit near 18 x 14 x 8 in (45 x 35 x 20 cm), typical overhead cabin case limits sit near 22 x 14 x 9 in (56 x 36 x 23 cm).

Weight policies differ by carrier; major U.S. airlines frequently impose no strict cabin-weight cap, low-cost international operators often limit cabin items to 7–10 kg. Confirm fare rules during booking to avoid unexpected fees for a second cabin-sized piece.

Security packing: place liquids in containers ≤ 100 ml, gather them in a clear quart-size bag kept in the personal item for screening. Store laptops and tablets in the smaller item for quick removal at checkpoints.

Boarding protocol: if overhead bins are full, expect the larger case to be gate-checked; budget carriers sometimes gate-check without refund for non-priority fares. Purchasing priority boarding or a larger cabin allowance ahead of time reduces the risk of gate check charges.

Airline examples, typical practice: Delta, American, United generally include a personal piece plus a main-cabin case on most fares; Ryanair, Wizz Air usually include only a very small personal bag with basic fares, larger cabin pieces require priority purchase.

Quick checklist: measure dimensions with a tape, verify the specific carrier’s size and weight limits online, redistribute heavy items into checked baggage when limits are exceeded, use compression organizers to maximize usable volume.

Which airlines allow a rucksack plus a cabin bag as two separate items?

Short answer: Major full-service carriers–Delta Air Lines, American Airlines, United Airlines, Southwest Airlines, JetBlue, British Airways, Air Canada, Lufthansa–permit one overhead cabin suitcase plus one personal item such as a rucksack or tote as two distinct pieces on standard economy fares.

Typical size limits: overhead cabin suitcase: 22 x 14 x 9 inches (56 x 36 x 23 cm); personal item: 18 x 14 x 8 inches (45 x 35 x 20 cm) to fit beneath the seat. Weight rules differ by carrier: many North American airlines do not enforce a strict weight for cabin pieces on domestic sectors; several European and Asian operators limit cabin pieces to roughly 7–10 kg (15–22 lb). Always verify the exact dimensions and weight on the carrier’s official page before travel.

Low-cost carriers: Spirit Airlines, Frontier Airlines, Ryanair, Wizz Air typically include only a very small personal item free; a standard overhead cabin suitcase usually incurs a fee unless priority boarding or a seat/baggage bundle was purchased. Purchase cabin allowance or priority at booking when two pieces are required to avoid gate charges.

Practical recommendations: designate the smaller item for under-seat storage; measure both pieces with wheels plus handles attached; weigh items at home with a hand scale; save a screenshot of the carrier’s baggage rules in the booking confirmation; buy upgraded baggage privileges before arrival at the airport when policies appear restrictive.

Measure and weigh a daypack plus a cabin bag to meet airline requirements

Measure external dimensions including wheels, side pockets and retractable handles; target at least 2 cm (0.8 in) under the carrier’s published maximum on each axis and aim for total mass 10% below the stated allowance (or 1–2 kg under if allowance listed in kilograms).

Step-by-step measuring and weighing

Use a fabric tape measure for length × width × height (record in cm and inches). Include projections: wheels and extended handles count toward height. For depth, compress side pockets naturally but do not squeeze main structure to fake a smaller size. Record empty bag mass first, then packed mass.

Preferred weighing methods:

• Hanging luggage scale: attach by top handle, lift until stable; read in kg or lb.
• Bathroom scale: weigh self, weigh self holding packed item, subtract; repeat twice and average.
• Airport self-service scales: use only if earlier methods unavailable; many enforce rounded limits.

Practical tips to pass gate checks

Weigh packed items at home with the same device planned for travel; keep spares of travel-size toiletry bottles and swap heavy items into checked hold only if necessary. If mass is borderline, remove metal-heavy objects (large chargers, spare batteries) or transfer dense items into the larger cabin-sized case. Use compression cubes to control external dimensions without overstuffing; do not force closures beyond manufacturer zippers–tight seams are inspected.

Packing strategy for daypack vs cabin suitcase at security

Place all liquids in 100 ml containers; consolidate into a single clear 1‑quart resealable bag positioned in the topmost pocket of the daypack for immediate presentation at the checkpoint.

Electronics

Laptops, tablets, large cameras: store inside a thin padded sleeve located in an exterior compartment of the cabin suitcase or daypack where removal requires a single motion; place chargers, power banks, headphones inside a small pouch to prevent loose items scattering into the bin.

Documents, medication, valuables

Travel documents: keep passport, boarding pass, prescription medication, wallet in the outermost pocket of the daypack for instant access; medications should remain labelled in original containers.

Prioritize placement of items that commonly require removal at screening near zipper openings for one‑handed access; orient zippers upward to speed transfer into bins.

Wear slip‑on shoes to accelerate the footwear step at the checkpoint; place belts, metal accessories inside a small pouch stored in the top compartment of the cabin suitcase for rapid bin placement.

Use packing cubes to separate clothing by inspection risk: toiletries in one cube, electronics accessories in another, clean garments in a third. Keep one empty resealable bag accessible for small items removed during screening so all such items return into a single container.

What to do at boarding if overhead bins are full: gate-check and stow options

Request a gate-check tag immediately when overhead storage is full.

1. Assess space: slide a small personal item under the seat; compress soft packs to fit available slots.
2. Ask the gate agent about gate-checking for bulky rollers or soft-sided cases; keep the printed tag stub for pickup proof.
3. Retain on-person essentials: passport, medication, wallet, phone, laptop with installed battery; do not gate-check spare lithium batteries or portable battery packs.
4. Protect fragile contents by wrapping with clothing or bubble wrap, placing electronics in protective sleeves, sealing loose straps to prevent snagging during transfer to cargo.
5. Label an internal pocket with contact information; attach an external identifier such as a bright ribbon for quick recognition on arrival.
6. Confirm retrieval point: some carriers return gate-checked items at the jet bridge, others route them to the main carousel; verify the procedure with the agent before handing over the item.
7. Check fee rules aloud at the gate: many legacy carriers waive gate-check charges on domestic routes, while discount operators may apply a fee; obtain verbal confirmation when a tag is issued.
8. Seek alternative onboard stowage if available: forward closet, galley space, bulkhead area; accept crew-offered solutions only when valuables and batteries remain onboard.
9. If overhead space is likely to remain scarce, buy priority boarding or consolidate multiple pieces into a single soft-sided pack for easier compression and placement.
10. If damage or loss occurs, present the gate-check receipt immediately at the airline’s baggage service desk; file a written report before leaving the airport.

• Quick checklist at boarding: gate-check tag, retain stub, remove valuables/meds, secure batteries, wrap fragile items, confirm pickup location.
• Regulatory note: spare lithium cells must travel in the cabin per transport rules; consult the airline at the gate if unsure.

Choose a fare or status that explicitly permits an overhead-bin cabin piece to secure a daypack alongside a standard cabin-sized bag

Basic-economy tickets most often restrict to a single under-seat personal item; standard economy usually allows a personal item plus one cabin-sized bag stowed in the overhead; premium-economy, business-class, first-class fares commonly permit two cabin-sized pieces plus a personal item. Low-cost carriers frequently limit free allowance to a very small under-seat item unless priority boarding or a paid add-on is purchased; full-service carriers bundle overhead access into higher fare buckets or elite benefits.

Typical size/weight benchmarks

Common maximum for a cabin-sized piece on major U.S. airlines: 22 x 14 x 9 in (56 x 36 x 23 cm). European low-cost free personal-item limits often near 40 x 30 x 20 cm. Weight caps for cabin pieces vary: many U.S. carriers do not publish a strict weight limit, while several international airlines enforce 7–10 kg (15–22 lb) for hand-portable pieces. Checked-bag free allowance increases with fare class or elite tier; common checked weight allowance for higher fares or elite members: 23 kg (50 lb) per piece or 32 kg (70 lb) in premium cabins on some international routes.

Actionable steps to guarantee two items in-cabin

Book a fare that explicitly lists “one cabin bag” or “two cabin bags” in the fare inclusions; confirm policy per flight number during purchase. Purchase priority boarding or a cabin-bag add-on at booking to bypass basic-fare restrictions. Use a co-branded premium credit card or elite status to claim waived cabin fees or an extra in-cabin piece; verify the card or tier policy before travel. At check-in, request an upgrade or paid carry allowance early; gate purchases often cost more. Measure items with a 56 x 36 x 23 cm template; pack heavier items in checked pieces purchased in advance to avoid gate-check fees.

FAQ:

Can I bring a backpack and a carry-on bag on the plane?

Most airlines allow one carry-on bag plus one personal item per passenger. A backpack can serve as either the carry-on (placed in the overhead bin) or the personal item (stowed under the seat), depending on its size. Policies vary by carrier and fare type, so check the specific airline’s allowance before you travel to avoid surprises at the gate.

What are typical size and weight limits for a carry-on and a personal item?

Size and weight limits differ between airlines. Common maximum dimensions for a carry-on are near 22 x 14 x 9 inches (56 x 36 x 23 cm), while a personal item must be noticeably smaller so it fits under the seat. Some carriers also apply weight limits (often 7–10 kg / 15–22 lb) for either or both items. Low-cost carriers tend to have stricter limits. Measure your backpack and bag and compare those measurements to the airline’s published limits before packing. If your backpack is soft-sided and compresses, it may still pass as a carry-on even if a few centimeters over, but rigid suitcases are less forgiving.

Will I have to remove electronics and liquids from both bags at security?

Security procedures require you to place liquids in a clear quart-sized bag and remove large electronics like laptops or tablets for screening, unless you have an expedited screening program such as TSA PreCheck in the United States. Expect to place both the backpack and the carry-on through the X-ray conveyor. For efficiency, put liquids and loose items in easily accessible pockets so you can remove them quickly at the checkpoint.

If I book a basic or economy fare on a budget airline, can they still charge me for a carry-on if I already have a backpack?

Yes. Some budget airlines only include a small personal item with the base fare and charge extra for a standard carry-on. In that case, a backpack sized to fit under the seat will be accepted as the included personal item, but a larger backpack intended for the overhead bin may trigger a fee. Read the fare rules before booking and consider upgrading or buying carry-on allowance online if you need both items in the cabin.

What happens if my carry-on doesn’t fit in the overhead bin at boarding?

If a bag exceeds available bin space or the airline’s size policy, gate agents may ask you to gate-check the item. Gate-checked luggage is tagged and placed in the aircraft hold; you generally retrieve it at the baggage claim after landing. Gate-checking is free on many carriers but some apply fees. To avoid this, pack essential items and valuables in your personal item so you still have what you need during the flight, choose soft-sided bags that compress, arrive early to secure bin space, and, when possible, stow a slim personal item under the seat while placing a compressed carry-on above.
