FREQUENT FLYER GLOSSARY
What is denied boarding?
Denied boarding, often called bumping, is an airline's refusal to carry a passenger on a flight even though that passenger holds a reservation and presented themselves for boarding as required. Whether the refusal creates a right to money, or only to rebooking, depends on the jurisdiction and on whether the passenger gave up the seat voluntarily. In the European Union, Regulation (EC) No 261/2004 defines denied boarding as a refusal to carry passengers on a flight although they presented themselves for boarding under the conditions laid down in Article 3(2), except where there are reasonable grounds to deny them boarding, such as reasons of health, safety or security, or inadequate travel documentation.

Key takeaways
- Denied boarding is a refusal to carry a passenger who holds a reservation and presented for boarding as required; under European Union rules a refusal on health, safety, security or travel-document grounds is not denied boarding. [1]
- European Union carriers must call for volunteers before denying boarding against anyone's will, and only the involuntary cases attract the fixed Article 7 sums on top of re-routing or reimbursement and care. [1]
- The United States uses the same sequencing: the Department of Transportation requires airlines to look for volunteers before bumping anyone involuntarily. [2]
What counts as denied boarding?
The everyday situation is familiar: an airline has accepted more reservations than the cabin can hold, and someone with a valid booking is left behind at the gate. United States Department of Transportation consumer material calls this an oversale and the passenger bumped. [2]
European Union law uses a narrower test. Regulation (EC) No 261/2004 defines denied boarding as a refusal to carry passengers on a flight although they presented themselves for boarding under the conditions laid down in Article 3(2), except where there are reasonable grounds to deny them boarding, such as reasons of health, safety or security, or inadequate travel documentation. [1] Those conditions require a confirmed reservation and presentation for check-in as stipulated and at the time indicated in advance and in writing by the carrier, tour operator or authorised travel agent or, where no time is indicated, not later than 45 minutes before the published departure time. [1]
Two boundaries follow from that wording. A refusal made on safety, security, health or documentation grounds falls outside the definition altogether. [1] And the term is deliberately kept apart from cancellation, which the same regulation defines as the non-operation of a flight that was previously planned and on which at least one place was reserved; cancellation carries its own assistance and compensation test, including a defence where the carrier proves extraordinary circumstances that could not have been avoided even if all reasonable measures had been taken. [1] Flight length and delay are treated elsewhere in the regulation again, so a late arrival is not the same event as a refused boarding. [1]
How are voluntary and involuntary cases separated?
Regulation (EC) No 261/2004 sets out a two-step procedure. Where an operating air carrier reasonably expects to deny boarding on a flight, it must first call for volunteers prepared to surrender their reservations in exchange for benefits under conditions agreed between the passenger and the carrier, and those volunteers are also assisted under Article 8, in addition to the agreed benefits. [1] A volunteer is defined as a person who presented for boarding under Article 3(2) and responded positively to that call. [1]
Only where too few volunteers come forward may the carrier deny boarding to passengers against their will, and those passengers must then be compensated immediately under Article 7 and assisted under Articles 8 and 9. [1] The sequence is mandatory rather than a matter of goodwill: the regulation's stated aim is to reduce the number of passengers denied boarding against their will by requiring carriers to call for volunteers instead. [1]
Why does the split decide whether money is owed?
In the European Union the fixed sums attach to involuntary denial of boarding. The amount is set by the great circle distance of the flight, using the last destination at which the denial of boarding delays the passenger's arrival beyond the scheduled time. [1]
| Flight distance | Amount |
|---|---|
| 1,500 kilometres or less | EUR 250 |
| Intra-Community flights of more than 1,500 kilometres, and other flights between 1,500 and 3,500 kilometres | EUR 400 |
| All flights not falling in the two rows above | EUR 600 |
The carrier may reduce the sum by 50% where it re-routes the passenger to the final destination and arrival is no more than two hours late on flights of 1,500 kilometres or less, three hours on intra-Community flights over 1,500 kilometres and other flights between 1,500 and 3,500 kilometres, or four hours on longer flights. [1] Payment must be made in cash, by electronic bank transfer, bank order or bank cheque, or, with the passenger's signed agreement, in travel vouchers or other services. [1] Alongside the money, involuntary passengers are owed the Article 8 choice between reimbursement within seven days of the parts of the journey not made and re-routing to the final destination, plus the Article 9 care: meals and refreshments in reasonable relation to the wait, hotel accommodation and transport where a stay becomes necessary, and two calls or emails. [1] [1]
Volunteers sit outside the payment rule. The regulation preserves a passenger's right to further compensation but expressly disapplies that provision to passengers who voluntarily surrendered a reservation, so a volunteer's entitlement is what was agreed at the airport, together with the Article 8 assistance. [1]
How does the United States treat involuntary denied boarding?
The Department of Transportation's consumer guide separates the two cases in the same order. It requires airlines to seek out people willing to give up their seats for compensation before bumping anyone involuntarily, and it states that the Department has not mandated the form or amount of compensation offered to volunteers, although carriers must tell a volunteer whether they might be bumped involuntarily and what would then be due. [2]
Passengers bumped against their will are, with a few exceptions, entitled to denied boarding compensation in the form of a cheque or cash, and the minimum depends on the price of the ticket and the length of the delay; the Department's requirements are minimums, so an airline may pay more. [2] The guide carries a warning that some of its content may have been superseded by later rulemaking, so the figures below are best read as the amounts published there.
| Substitute arrival compared with the original schedule | Minimum |
|---|---|
| Within one hour of the original scheduled arrival | No compensation |
| One to two hours late, or one to four hours late on international flights | 200% of the one-way fare to the final destination that day, or USD 1,075, whichever is lower |
| More than two hours late, more than four hours late on international flights, or no substitute transport arranged | 400% of the one-way fare, or USD 2,150, whichever is lower |
The payment sits on top of the ticket, which the passenger keeps and can use on another flight, and passengers who paid for optional services such as seat selection or checked baggage that were not delivered must be refunded those amounts. [2] A bumped passenger may insist on a cheque rather than a voucher or free flight, and cashing the cheque or accepting the free flight will probably end the ability to pursue more money later, with about 30 days from the date on the cheque to decide whether to accept it. [2]
Exceptions and limits
- Late arrival at check-in. European Union protection depends on presenting for check-in within the carrier's written deadline or, where none was given, 45 minutes before departure. [1] The Department of Transportation guide says a passenger who misses the airline's check-in deadline may have lost the reservation and the right to compensation if the flight is oversold. [2]
- Which flights European rules reach. Regulation (EC) No 261/2004 applies to passengers departing from an airport in a Member State, and to passengers departing a third-country airport for a Member State on a Community carrier unless they received benefits or compensation and assistance in that third country. [1] It does not apply to passengers travelling free of charge or at a reduced fare not available directly or indirectly to the public, but it does apply to passengers holding tickets issued under a frequent flyer programme. [1]
- United States carve-outs. The consumer guide lists cases where compensation is not required, including substitution of a smaller aircraft, flights on aircraft with 30 to 60 seats where a safety-related weight or balance limit applies, charter flights, aircraft holding fewer than 30 passengers, international flights inbound to the United States, and flights between two foreign cities. [2]
- After boarding has started. Once a passenger has been accepted for boarding or has boarded, United States airlines may not require them to leave the aircraft unless removal is needed for safety, security or health reasons, or because of unlawful behaviour. [2]
- No waiver by contract. European Union obligations to passengers cannot be limited or waived, in particular by a derogation or restrictive clause in the contract of carriage. [1]
Frequently asked questions
Does denied boarding compensation apply to award tickets?
In the European Union, yes: the regulation expressly covers passengers holding tickets issued under a frequent flyer programme or other commercial programme by an air carrier or tour operator. [1] In the United States, where a ticket shows no fare, such as a frequent flyer award ticket, the Department of Transportation guide bases compensation on the lowest cash, cheque or credit card payment charged for a ticket in the same class of service on that flight. [2]
Can I be removed from a flight after I have boarded?
Under United States practice, airlines generally select passengers to bump at the gate before they are accepted for boarding, and once a passenger has been accepted for boarding or has boarded they may not be required to leave unless removal is needed for safety, security or health reasons or because of unlawful behaviour. [2]
What do I have to be told at the airport?
In the European Union, a carrier that denies boarding must give each affected passenger a written notice setting out the compensation and assistance rules, together with the contact details of the national body designated to enforce the regulation. [1] In the United States, airlines must give every passenger bumped involuntarily a written statement of their rights and an explanation of how the carrier decides who boards an oversold flight. [2]
Where can I complain if the airline does not pay?
The Department of Transportation requires airlines to acknowledge consumer complaints within 30 days and to send written responses within 60 days, and passengers who are not satisfied may then complain to the Department itself. [5] In the European Union, each Member State designates a body responsible for enforcing the regulation, and any passenger may complain to it about an alleged infringement. [1]
