What is voluntary denied boarding?

How does the volunteer process work at the airport?

An oversold flight is one where more confirmed seats have been sold than the aircraft can carry, a practice airlines use to offset passengers who never turn up. Overbooking is not illegal, and most airlines overbook their scheduled flights to some extent to compensate for no-shows, which is why passengers are sometimes left behind. [5] When an oversale occurs, DOT requires airlines to ask people who are not in a hurry to give up their seats voluntarily in exchange for compensation, before anyone is bumped against their will. [5]

The search happens at check-in or in the boarding area: airline employees start looking for volunteers once it appears the flight is oversold, and a passenger who is not pressed for time can give the reservation back to the carrier in exchange for compensation and a later flight. [5] Airlines generally offer a free trip or other transportation benefits, issue staff guidelines for bargaining, and may select the volunteers willing to sell their reservations back for the lowest price. [5] Because carriers may negotiate with passengers for a mutually acceptable deal, the same flight can produce different outcomes for different volunteers. [5]

One disclosure rule shapes the conversation. DOT requires the airline to advise any volunteer whether that volunteer might instead be bumped involuntarily and, if so, what compensation would be due, so the volunteer can weigh the offer against what refusing would bring. [5]

How does volunteer pay compare with denied boarding compensation?

Being refused boarding against your will is a statutory matter, and the payment scale is fixed at a minimum by DOT. A volunteer payment sits outside that scale, because the amount and the form are whatever the two sides agree. [5]

The involuntary scale below shows the number a volunteer is usually trying to beat, as stated in DOT's consumer guide checked on 18 October 2026. [5]

Award tickets still carry a minimum: where a ticket does not show a fare, such as a frequent flyer award ticket, the involuntary amount is based on the lowest cash, check or credit card payment charged for a ticket in the same class of service on that flight. [5] Note that a passenger whose replacement flight lands within an hour of the original schedule receives nothing under the involuntary scale, which is one reason a negotiated volunteer offer can beat simply being refused. [5]

Can you still change your mind after you volunteer?

Until the exchange is agreed, nothing is settled: DOT has not mandated the form or amount of volunteer compensation, and the carrier and passenger negotiate the terms. [5] That is the moment to ask about the next flight on which the airline can confirm a seat rather than a standby place, and about meals, a hotel room, transfers between hotel and airport, or a phone card — items that otherwise come out of the payment offered. [5] If you are offered a free ticket or a transportation voucher in a dollar amount, DOT advises asking how long it is valid, whether it is blacked out during holiday periods when you might want to use it, and whether it can be used for international flights. [5]

The commitment point is boarding rather than the conversation. Airlines generally identify passengers for involuntary bumping at the gate before they are accepted for boarding, and once a passenger has been accepted for boarding or has already boarded, the carrier is not permitted to require that passenger to leave the aircraft unless removal is required for safety, security or health reasons, or because of the passenger's unlawful behaviour. [5] Accepting a payment is usually final in the other direction as well: DOT's guidance says that once you cash a check or accept a free flight you will probably lose the ability to pursue more money from the airline later on. [5] You always keep the original ticket and can use it on another flight, and a passenger who makes their own arrangements can request an involuntary refund for the flight given up. [5]

Exceptions and limits

• Which flights. The DOT bumping rules described here do not apply to charter flights, to scheduled flights operated with aircraft holding fewer than 30 passengers, to international flights inbound to the United States, or to flights between two foreign cities. [5]
• Other jurisdictions. The European Commission has its own rule on bumpings that occur in an EC country, so a flight governed by that rule is outside the US framework above. [5]
• Aircraft substitution. If a carrier substitutes a smaller aircraft for the one planned, it is not required to pay passengers displaced as a result, and on aircraft with 30 to 60 seats no payment is required where displacement follows safety-related weight or balance constraints — which lowers the involuntary benchmark a volunteer might otherwise cite. [5]
• Airline contract terms. Each airline has its own contract of carriage, and those rules can differ between carriers, so volunteer terms are worth reading for the specific carrier and fare. [5]
• Time limit on involuntary payments. A passenger refused boarding involuntarily who is paid by check usually has 30 days from the date on the check to decide whether to accept the amount, and remains free to decline it; where the displacement costs more than the airport payment, a higher settlement can be sought from the airline's complaint department. [5]
• Escalation. Airline customer service representatives at the airport may be able to write checks for passengers who are bumped and settle routine claims, and if a problem cannot be resolved there, DOT requires airlines to acknowledge consumer complaints within 30 days and to send a written response within 60 days. [7]
• Status of this guidance. DOT posts this consumer guide with a notice that some or all of the information may have been superseded by statute or rule-making and that continued reliance on it is not advised. [5]

Frequently asked questions

Do you have to accept the airline's first offer?

No. DOT has not mandated the form or amount of volunteer compensation and carriers may negotiate a mutually acceptable deal, though airlines may deliberately select the volunteers willing to sell their reservations back for the lowest price. [5]

Is a voucher worth as much as cash?

Only if its conditions suit you. Ask how long the voucher is valid, whether it is blacked out during holidays, and whether it can be used on international flights before you treat it as equivalent to money. [5]

Can the airline make you get off after you have agreed to volunteer?

Once a passenger has been accepted for boarding or has boarded, the carrier is not permitted to require them to leave unless removal is needed for safety, security or health reasons, or because of unlawful behaviour. [5]

Does the one-hour rule apply to volunteers?

No. The rule that pays nothing when the replacement flight arrives within an hour belongs to the involuntary scale; what a volunteer receives is negotiated, not set by that table. [5]

Where do you complain if a volunteer deal goes wrong?

Start with the airline. DOT requires carriers to acknowledge consumer complaints within 30 days and to respond in writing within 60 days, and a complaint can then be taken to DOT if the answer is unsatisfactory. [7]
