Airline oversold my flight at the airport: who helps?

Summary

If an airline oversold the flight and you are denied boarding, who helps first is always the airline disruption or rights desk at the airport: care, a written reason, and a choice of rebooking or refund. What you can insist on next depends on where the flight is leaving from and which airline is operating it. On many UK linked flights, UK261 style rules apply. Overseas, you may instead rely on local or EU passenger rules, the airline’s contract, or a package holiday scheme. The CAA, AviationADR / CEDR, and Citizens Advice help after the airport scramble. None of them will put you on another plane today.

Key information

• Get the airline to say in writing whether this is denied boarding (oversold / no seat), a delay, a cancellation, or a “reasonable” refusal (documents, health, safety, security).
• Keep boarding pass or mobile boarding pass screenshot, booking reference, flight number, gate photos, staff names, and receipts for food, hotel, and transfers.
• Volunteer bump (you accept an offer) is a negotiated deal plus rebooking or refund. Involuntary bump (they remove you against your will after on time check in) usually triggers fixed compensation on covered flights, plus care and the rebooking or refund choice.
• UK airport (any airline): UK261 style rights usually cover flights departing the UK. Ask for care and assistance now, then rebooking at the earliest opportunity or a refund, and for involuntary bump ask for the fixed compensation figure in writing.
• Overseas, flying into the UK: UK rules often cover arrivals on a UK or EU airline. On a non UK / non EU carrier into the UK, UK261 may not apply. Still demand care and a written plan, then check that airline’s national enforcement body or contract terms.
• Overseas, not heading to the UK on a UK or EU carrier: UK261 may not help. Use the operating airline desk, the local national enforcement body (for EU airports, often the local NEB for Regulation 261), your travel insurer emergency line if covered, and FCDO travel advice only for safety and consular orientation, not compensation.
• Outcomes to ask for on covered flights: care and assistance; rebooking or refund; fixed compensation bands for involuntary denied boarding (see CAA denied boarding); expenses with receipts if you self arranged care; later complaint win via ADR or CAA PACT.
• Package holidays with ATOL / ABTA protection use different doors if the organiser fails. Ordinary oversold seats on a simple flight ticket usually stay with the airline and aviation ADR.
• The CAA publishes denied boarding guidance, expects an airline complaint first (often up to about 8 weeks), then points you to AviationADR or CEDR if the airline is in an approved ADR scheme (those can impose outcomes). If there is no ADR, PACT may review UK261 style complaints and lean on the airline, but cannot impose a binding award. The CAA will not rebook you at the airport or pay you at the desk.
• Citizens Advice maps rights, complaint structure, package versus flight only, and later card routes. They will not attend the airport or chase the airline for you. Start with holiday cancellations and compensation.
• Resolver offers a free complaint workspace. Some airlines reject third party portals.

Practical guidance

• At the airport (UK or overseas): operating airline disruption desk for care, written denial reason, and rebooking or refund choice.
• If staff are overwhelmed: arrange reasonable food and hotel yourself, keep receipts, claim later (CAA tip on self arranged care).
• Travel insurer emergency line if you have cover for missed connections or delayed departure.
• After you leave: airline complaints online with evidence and the outcome you want.
• Optional: Resolver if that airline accepts it.
• If refused or ignored: AviationADR or CEDR when the airline is a member (CAA complaints map). If no ADR: CAA PACT for in scope UK261 denied boarding issues.
• Package booking: ABTA / ATOL as well as the airline.
• Court as last resort if free doors fail and the sum is worth it.
• Ask the Shaman: free door routing.
