Direct recommendation: Use a commercial short-term baggage service near Sea–Tac or downtown for the fastest, most transparent option – typical rates run about $5–12 per item per day, with hourly options available for short stays; book online to lock a time slot and reduce wait.
There are no public locker banks inside the main SEA terminal. Ticketed passengers may check extra items at airline check-in counters; customary first extra-bag fees on domestic carriers are approximately $30–35 (verify carrier rules for weight/size). For short breaks between flights, choose a provider with a downtown location to minimize transit time.
Link Light Rail links the terminal to Westlake Station in roughly 35–40 minutes, with trains every 6–15 minutes depending on daypart; one-way fares are generally a few dollars – confirm current rates on Sound Transit. Plan 45–75 minutes from gate to a downtown drop-off point, allowing time for deplaning, walking, and rail transfer.
Prefer vendors that publish declared-value coverage and show proof of insurance; many offer protection limits in the $1,000–2,500 range per item. Photograph items, remove irreplaceable valuables, and retain the digital receipt/QR code. Confirm operating hours (many downtown partners run ~07:00–22:00; some hotel-linked sites are 24/7) to match arrival and pickup windows.
Check cancellation, late-pickup and liability terms before committing – added fees for missed pickups commonly range $5–20 depending on provider and duration. For quickest processing, arrive with ID and reservation code, note exact pickup address, and verify customer-service contact information at booking.
Baggage-holding options at SEA (Tacoma International)
No official left-baggage facility operates inside SEA terminals; use alternatives listed below.
1) Airline checked-item service – Most carriers accept checked bags at ticket counters and curbside check-in for same-day handling; policies differ by airline (size/weight limits, surcharges, maximum hold time). Contact the carrier or review its baggage policy online before arrival.
2) Downtown and neighborhood storage networks (examples: Bounce, Stasher) – Multiple partner shops and lockers accept items for short-term drops. Typical rates range roughly USD 6–15 per item per day; reservations recommended. Prepare government ID, digital booking confirmation and a photo of each item; oversized cases may incur extra fees.
3) Hotel concierge/long-stay lodging – Many hotels near the terminals and in the city will hold bags for guests at no charge or for a modest fee for non-guests. Confirm acceptance times and retrieval window with the hotel reception in advance.
4) Door-to-door shipping services – Third-party carriers offer same-day or overnight shipments to a hotel or residence; useful for multi-day holds or when avoiding public transit with heavy items. Expect higher cost for expedited delivery and for oversized or heavy pieces. Hazardous materials, perishables and firearms are normally prohibited.
5) Transit and timing – Link Light Rail from SEA to downtown Westlake Station takes about 35–40 minutes; trains run frequently throughout the day. Factor this transfer time plus any walking between storage partner locations when planning pick-up or drop-off windows.
6) Security and paperwork – Keep passports, medications, cash and valuable electronics on person. Photograph contents, label items, request a written receipt with provider contact and liability/insurance limits, and note operating hours. Verify the provider’s claims procedure before handing over items.
7) Where to confirm – Visit the official SEA website or contact SEA customer service for terminal maps and transit information; verify airline-specific baggage hold rules directly with the carrier.
Where to find official baggage storage counters and self-service options at SEA
Visit the SEA Guest Services / Lost & Found counter in the Main Terminal (central ticketing and claim zone) for official handling; many carriers operate transfer/ground-service desks at the ticketing level that accept same‑day holds for connections – confirm hold policies with the airline desk before leaving the terminal.
No network of coin‑operated lockers exists inside the concourses; the primary on‑site option is Guest Services or individual carrier counters. For multi‑day needs, commercial off‑site providers maintain staffed drop‑off points and app‑managed lockers within a 5–10 mile radius of SEA.
Common third‑party providers: Bounce, Vertoe, LuggageHero. Typical pricing ranges: $1–7 per hour or $5–15 per day depending on location, insurance add‑ons and peak demand. Book in advance via each provider’s app or website, pick a location labeled SeaTac/Angle Lake or downtown Link Light Rail, confirm operating hours and required ID, and save the digital receipt and access code.
Practical recommendations: photograph contents and exterior tags before handover; request a written receipt or barcode; buy the provider’s insurance or verify travel insurance limits for high‑value items; for airline gate‑check or transfer holds obtain written confirmation with expected retrieval time.

How much bag storage costs at SEA and which payment methods are accepted
Plan on paying roughly $5–$12 per item per 24 hours near SEA: app-based networks typically charge about $5–$8/day (or $1–$2/hour with a daily cap), coin- or card-operated lockers where available run about $6–$12/day depending on size, and staffed counters or hotel desk drops commonly set flat daily fees of $7–$15 per piece.
Longer-term pricing: weekly caps usually fall between $30 and $60; monthly options commonly range $90–$150. Oversize items such as bikes, skis or extra-large duffels often carry surcharges of $8–$25 per item. Extended-hold policies (7–14+ days) can trigger progressive billing, storage-to-abandonment fees or mandatory collection notices–review provider terms before payment.
Payment methods accepted: major credit and debit cards (Visa, Mastercard, American Express) are universally accepted; third‑party apps also accept Apple Pay, Google Pay and PayPal. Contactless tap-to-pay is common at kiosks and staffed counters; cash is frequently declined by app hosts and some terminals, though a few staffed desks will accept it. Digital receipts, item photos and basic insurance are standard when paid via card or app.
To reduce size surcharges and speed handling between terminals, prefer compact wheeled bags; suggested options and size guides available at best travel duffel bags with wheels for women.
Operating hours, maximum storage duration and late-pickup fees
Verify hours and retention rules with the official SEA baggage service before arrival; staffed counters generally run roughly 06:00–22:00 local time, while automated locker systems (when present) typically allow 24/7 access.
- Operating hours
- Staffed baggage counters: commonly open daily from about 06:00 to 22:00; holiday schedules may differ – confirm on the operator’s website or by phone.
- Automated lockers: when available, accessible round-the-clock; some machines require credit-card payment only and provide timed access codes.
- After-hours service: a few providers offer emergency collection/drop-off for an extra fee; contact details appear on receipts and facility signage.
- Maximum retention duration
- Short-term lockers: typical limits range from 24 to 72 hours; automated systems often enforce the limit automatically.
- Staffed left-baggage counters: standard retention periods are usually 7–30 days depending on the vendor; extended holds (up to 90 days) require prior arrangement and may incur additional charges.
- Unclaimed property policy: items left past the agreed retention window are frequently transferred to long-term storage, returned to sender (if contact info exists), auctioned, or disposed of according to the provider’s written terms.
- Late-pickup fees and penalties
- Grace period: many operators allow a short grace period (0–24 hours) before late fees begin; confirm the exact grace window at drop-off.
- Typical fees: daily surcharges commonly range from $5 to $20 per item per day for late retrieval; small-item rates may be lower, oversized-item surcharges higher.
- Flat handling/processing: providers may apply a one-time unclaimed-item fee (often $25–$100) prior to final disposition or shipping.
- High-value or restricted items: additional handling charges, insurance requirements, or refusal of acceptance are possible; unclaimed high-value goods usually require identity verification and extra administrative fees for release.
- Nonpayment consequences: failure to pay accrued fees can trigger disposal, auction, or third-party shipment; retain receipts and the booking reference to dispute charges if necessary.
- Practical actions: keep the receipt and reference number, photograph contents and tags, provide a reachable phone/email, notify the operator immediately if pickup will be delayed, and consider arranging courier pickup or off-site long-term storage if the intended hold exceeds vendor limits.
Size, weight limits and items prohibited from terminal storage at SEA
Limit each deposited item to 62 linear inches (length + width + height / 158 cm) and 50 lb (23 kg) as a baseline; oversized or heavier pieces will be refused or require special handling and surcharge.
Dimensional and weight specifics
Self-service lockers typically accept small-to-medium bags only; common locker internal dimensions are about 20 × 18 × 28 in (50 × 45 × 70 cm) with a practical weight limit near 30 lb (14 kg). Staffed baggage counters accept larger cases, sports gear and musical instruments, but most facilities set an upper acceptance envelope of roughly 80 linear inches (203 cm) and 70 lb (32 kg) unless advance approval is granted. Extremely large items (crates, furniture, motorized equipment) are declined.
Measurement method: add length + width + height (handle and wheels included). If an item is soft-sided, compression does not guarantee acceptance – final decision rests with the on-site operator. Expect extra fees or refusal for items exceeding the standard dimensions/weight; declare bulky items at drop-off to avoid delays.
Strictly prohibited and restricted items
Prohibited categories follow federal hazardous-material rules and common storage-operator policies: explosives and fireworks; flammable liquids and fuels (gasoline, lighter fluid); compressed gas cylinders (SCUBA tanks, propane); corrosives and strong oxidizers; radioactive material; infectious or biohazardous substances; large quantities of liquid (perishable groceries or open containers); loose lithium batteries and spare battery packs for electric tools – spare cells are not accepted for checked/left items. Live animals and perishable plants are refused.
Valuables generally not accepted for long-term holding: cash, stock certificates, passports, birth certificates, irreplaceable original documents and high-value jewelry. Firearms and ammunition often require prior authorization, unloaded condition, locked hard case and paperwork; many operators decline firearms entirely. Portable medical oxygen and prescription medications should remain with the passenger unless explicit acceptance is granted in writing by the facility.
Confirm restrictions and exact size/weight limits with the terminal storage operator before handing over items; keep the receipt, photograph contents of high-value pieces, and label items clearly to reduce disputes at retrieval.
Reserve online at least 24 hours before arrival; present government ID and the emailed QR code at drop-off.
Complete booking on the provider’s website or app by selecting date, drop-off window and service type (counter or locker). Enter full name exactly as shown on photo ID, a mobile number, an email address for confirmation, and the count and dimensions of each bag or item. Upload photos of high-value contents if optional insurance is offered. Pay with major credit or debit card; confirmation includes a reservation number, a scannable QR/pickup code and instructions.
Check‑in (drop‑off) procedure
Arrive 10–20 minutes before the reserved time slot. Present the reservation QR or printed confirmation and the same government ID used at booking. Staff will verify identity, affix barcode tags to each item, record tag numbers on the receipt and, when required, ask the signer to complete a short release form. Photograph tagged items and retain the receipt until collection. Avoid locking items that might require inspection; if a lock remains, leave key accessible or inform staff.
Retrieval and contingencies
Show the pickup QR/receipt and matching photo ID at the counter. Staff will scan codes, match tag numbers and release items after a brief visual check. For locker pickups, enter the one‑time code or scan the QR to open the assigned compartment; locker access times are typically limited to a few minutes. Lost receipts require presentation of government ID plus completion of an affidavit; expect a brief holding period while staff verify identity. For failed QR scans or missing confirmations, contact the provider via the helpline listed in the booking email; keep timestamped photos of item tags and the original confirmation to speed resolution.
For oversized, fragile or restricted items, reserve in advance and note any special handling needs on the booking form so staff can allocate appropriate space and equipment at drop-off.

Practical recommendations and rules
Always reserve online when available and confirm item limits and declared-value insurance. Require government ID at drop-off and retain the receipt number. Photograph contents and external condition before handover; label tags with contact details and pickup time. For high-value items, prefer insured commercial partners or hotel bell service rather than unattended lockers. Drivers using ride-hail should use the designated SEA terminal curbside code and follow signage to the official pickup lane to avoid fines.
Typical size/weight guidelines: many partners accept items up to 50 lbs and dimensions around 32 × 20 × 20 in for one item; oversized articles may incur an extra charge or be rejected. Prohibited goods usually include explosives, perishable foods, illegal substances and items requiring refrigeration.
For hands-free carry during transfers, keep passports, boarding passes and small electronics on person–suggested accessory: best messenger bag for across body.
