Denied Boarding and Overbooked Flights: What Are Your Rights?
Quick answer
Airlines sometimes sell more seats than exist because some passengers don't show up. If too many do, the airline first asks for volunteers, then may deny boarding to others. In the EU and UK, involuntary denied boarding generally entitles you to fixed compensation plus a choice of refund or rerouting, and care while you wait. In the US, compensation depends on the length of your delay. Always keep your boarding documents and ask for everything in writing.

Why airlines overbook
Airlines know from experience that a share of passengers on any flight will miss it or cancel late. Selling slightly more tickets than seats keeps aircraft full and, in theory, prices lower. Most of the time the numbers work out and nobody notices. Occasionally everyone turns up, and the airline has a problem to solve at the gate.
The sequence at the gate
- Volunteers are requested. The airline offers something, such as money, vouchers, or a later flight, to people willing to give up their seat.
- If not enough volunteer, the airline may deny boarding to some passengers against their will. The order it chooses is set by its conditions of carriage, often based on fare type, check-in time and status.
- The airline owes you assistance in many regions, including rebooking and help while you wait.
Voluntary or involuntary: the difference that matters
If you volunteer, you negotiate a deal, and the legal protections for involuntary denial may not apply in the same way. Before you accept, ask what exactly you are getting: how much compensation, in what form (cash, card refund or voucher), which flight you will be moved to and when it lands, and whether meals, a hotel and transfers are included. Get the offer in writing.
If you are denied boarding without volunteering, you are treated as an involuntary case and the regulation in your region applies, provided you meet the conditions below.
What the main regions provide
| Region | Involuntary denied boarding |
|---|---|
| European Union (EU261) | Fixed compensation based on flight distance, plus a choice between refund and rerouting, and care such as meals and accommodation if needed. |
| United Kingdom (UK261) | Similar structure to the EU rules for departures from UK airports and some UK carrier flights, with sums set in pounds. |
| United States (DOT rules) | Compensation scales with how late you arrive at your final destination versus your original plan, with higher limits for longer delays. |
| Elsewhere | Varies widely. Many countries have their own rules, and some have none beyond the airline's own policy. |
The exact amounts and thresholds are updated from time to time, so use the official passenger-rights page for your region to confirm the current figures rather than relying on a number you have seen elsewhere.
Conditions that usually apply
- You must have a confirmed reservation on the flight.
- You must have checked in on time by the airline's deadline and presented yourself at the gate in time.
- Denial must be due to the flight being oversold, not due to your documents, behaviour or a safety decision.
- The flight must fall inside the scope of the relevant regulation (for example, departing from a covered airport).
Compensation is generally not owed if you volunteer, if you lack proper travel documents, or if the airline denies boarding on legitimate safety or security grounds.
What to do at the gate
- Stay calm and polite. Staff have more discretion than you think, and they handle many angry people.
- Ask for the reason in writing and for confirmation that this is denied boarding.
- Keep everything: boarding pass, booking confirmation, receipts for meals or transport, and any notes with names and times.
- Do not rush to accept the first offer. If the situation is voluntary, offers often rise when few people respond.
- Ask about onward options, including other airlines, if the next seat on the same carrier is much later.
Claiming afterwards
If the airline does not pay what the law requires, write to its customer-relations team, quoting the regulation and attaching your documents. If it refuses or ignores you, you can usually escalate to the national enforcement body or an alternative dispute-resolution scheme. Time limits differ by country, so act promptly instead of waiting months.
How to reduce your risk of being bumped
Check in as early as possible, since last-to-check-in passengers are often first in line to be denied boarding. Pay attention to seat assignment, because passengers with confirmed seats and higher fare types are usually protected. Arrive at the gate in good time, and keep an eye on the live status of your flight through the day. If you are flexible, you can compare alternative departures on ScanFlyGo in advance.
Frequently asked questions
Is overbooking legal?
Yes, in most countries airlines may overbook, but they must follow passenger-rights rules about volunteers, compensation and assistance when too many people show up.
Should I volunteer to give up my seat?
Only if the offer suits you. Ask what you get, how long you will be delayed, and whether meals and accommodation are included, and get the terms in writing before you agree.
Do I get compensation if I am denied boarding against my will?
Often yes. EU and UK rules set fixed amounts, and US rules scale compensation with the delay to your final destination. Conditions apply, such as a confirmed booking and timely check-in.
Can an airline bump me after I have checked in?
Yes. Check-in does not guarantee boarding if the flight is oversold, though checking in early lowers your chance of being selected.
What if I miss the later flight the airline offers me?
If you accept a rebooking, you are responsible for being there, so make sure the time and terminal work for you. Ask about alternatives if the replacement flight is impractical.
The bottom line
Overbooking is legal but you are not powerless. Arrive early, hold a confirmed ticket, think carefully before volunteering, and ask the airline to state your rights and any offer in writing. Then let the facts decide. To compare options for your next trip, search live fares on ScanFlyGo, check popular routes, and track your flight before heading to the airport.
