Medical Equipment Delay on Flights: What Airlines Owe You

Medical equipment flight delay compensation rests on a layered framework that most passengers never invoke fully. Layer 1: the Air Carrier Access Act (ACAA) and 14 CFR Part 382 require US carriers (and foreign carriers operating to or from the US) to provide replacement equipment or alternative arrangements within 24 hours when medically necessary equipment is delayed. Layer 2: the Montreal Convention Article 22(2) caps baggage damage and delay liability at about USD 1,800 per passenger international, with mobility devices typically paid at full repair or replacement under DOT enforcement pressure. Layer 3: 14 CFR Part 254 caps domestic US baggage liability at USD 3,800 per passenger. Layer 4: the 2024 DOT refund rule entitles you to a cash refund if the underlying flight was cancelled or significantly delayed when you decline to fly. Most passengers settle for delayed-bag interim expenses and miss the medical-equipment-specific protections.

Medical equipment is not standard checked baggage. ACAA imposes airline obligations that do not apply to other delayed bags, including the 24-hour replacement window.

• ›

  Mobility devices: wheelchairs (manual, power, scooter), walkers, canes, prosthetics. Special handling required, damage liability often paid at full repair.

• ›

  Respiratory equipment: CPAP machines, BiPAP machines, portable oxygen concentrators (POCs). Required for medically dependent passengers.

• ›

  Diabetic supplies: insulin pumps, glucose monitors, insulin coolers, sharps containers. Time-sensitive replacement need.

• ›

  Cardiac and neurological devices: defibrillators, pacemakers (carry-on only), nerve stimulators with external components.

• ›

  Dialysis equipment: home hemodialysis machines, peritoneal dialysis supplies for traveling patients.

• ›

  Allergy and emergency response: EpiPens (carry-on per FAA), epinephrine auto-injectors, emergency anaphylaxis kits.

• ›

  Specialised feeding equipment: enteral feeding pumps, formula coolers for ketogenic or special-diet patients.

When a passenger's medical equipment is delayed in checked baggage, the airline has a positive obligation to provide alternative arrangements within 24 hours. This includes: locating the original bag and rush-delivering, providing a loaner unit (some airlines maintain CPAP and POC inventory at major hubs), arranging local rental at airline expense, or covering the cost of a passenger-arranged replacement. The obligation continues at no charge until the original equipment is delivered or the passenger declines further assistance. Failure to meet the 24-hour window is an ACAA violation, enforceable through DOT complaint with civil penalties up to USD 27,500 per incident or higher for systematic non-compliance.

Document the request and any airline response in writing. The 24-hour clock starts when you notify the airline, not when the airline acknowledges. Save the timestamp.

On international flights, Montreal Convention Article 22(2) caps baggage damage and delay liability at 1,288 SDR (about USD 1,800) per passenger. For mobility devices specifically, US carriers and most foreign carriers operating into the US voluntarily exceed the cap because of DOT enforcement pressure under ACAA. Repair or replacement is typically paid at full cost without depreciation. For domestic US flights, 14 CFR Part 254 sets the cap at USD 3,800 per passenger, and the same voluntary full-cost payment applies on mobility devices. Article 31 requires written notice within 7 days for damage and 21 days for delay or lost bag. See lost luggage on international flights: the $2,000 claim most miss and Montreal Convention baggage limit 2026.

When the underlying flight is cancelled or significantly delayed (3+ hours domestic, 6+ hours international) and you decline to fly, the 2024 DOT refund rule entitles you to a cash refund of the ticket value to the original payment method, processed within 7 business days for credit card purchases. The refund right is independent of the medical equipment claim. Stack the recovery: ACAA mobility assistance during the disruption, Montreal Convention damage or delay compensation for the equipment, DOT cash refund for the ticket.

ACAA, Montreal Convention, and DOT refund rule stack independently on a single disruption. Most passengers file only one claim and leave the others unclaimed.

• ›

  Medical necessity letter: from your prescribing physician confirming the equipment is medically required for travel.

• ›

  Equipment purchase receipt: anchors full repair or replacement value. Save the original invoice or insurance documentation.

• ›

  Photos before travel: pre-trip photos of the equipment in working condition, especially for mobility devices and high-value units.

• ›

  Bag tag and PIR (Property Irregularity Report): filed at the baggage office before leaving the airport.

• ›

  Airline notification timestamps: written record of when you reported the delay or damage and when the airline responded.

• ›

  Replacement or rental receipts during the delay: pharmacy supply purchases, equipment rentals, urgent care visits forced by delay.

• ›

  Special service request (SSR) codes in the booking: WCHC, WCHR, WCHS, MEDA, OXYG codes show the airline was on notice.

1. 1

   On the day of disruption, file the PIR at the baggage office before leaving the airport. Document the medical equipment specifically.

2. 2

   Notify the airline in writing immediately and request 24-hour replacement under ACAA. Cite 14 CFR Part 382 by name.

3. 3

   Save replacement and rental receipts during the delay window. The airline owes reasonable interim costs.

4. 4

   Within 7 days of damage discovery (or 21 days for delay or loss), send formal written notice citing Montreal Convention Article 22(2) and 31.

5. 5

   Include physician medical necessity letter, equipment receipt, photos, PIR reference, and itemised claim.

6. 6

   If the underlying flight was cancelled or significantly delayed and you declined to fly, file the 2024 DOT cash refund request in parallel.

7. 7

   Track the 7-business-day federal refund deadline.

8. 8

   If the airline refuses or delays, file an ACAA complaint at transportation.gov/airconsumer with explicit reference to the medical equipment.

See how to file an ACAA complaint and Montreal Convention claim denied: what to do next.

CPAP and BiPAP machines: typically allowed as a free additional carry-on under ACAA, do not count against the standard carry-on limit. If checked, the airline owes 24-hour replacement on delay. Most major US carriers (Delta, United, American) maintain loaner CPAP inventory at major hubs. Insulin pumps: must be carried on per FAA. If the pump fails or is damaged in airline custody, the airline owes Montreal Convention or 14 CFR Part 254 damage compensation plus reasonable interim insulin and supply costs. Portable oxygen concentrators: must meet FAA approval (POC list at faa.gov). The airline owes replacement or alternative arrangements within 24 hours of any equipment failure or delay. Documentation of the specific medical condition is required for FAA POC approval. See pregnant passenger with medical needs: rights and disability and medical flight rights 2026 guide.

• ›

  'You did not declare it as medical equipment': not a valid defence under ACAA. Any equipment with a clear medical purpose triggers the obligations regardless of declaration. Submit the medical necessity letter.

• ›

  'Replacement is not available locally': airline must arrange alternative (rental, courier, loaner). 'Not available' does not extinguish the obligation.

• ›

  'Standard baggage liability applies': the standard cap is the floor, not the ceiling. DOT enforcement pressure pushes carriers above the cap on medical equipment damage.

• ›

  'You should have used travel insurance': ACAA and airline obligations are primary. Travel insurance is secondary. File both, disclose each.

• ›

  'High-value items not declared': undeclared electronics or jewelry exclusion does not apply to medical equipment, which is necessary not optional.
