Cancelled flight? When the airline has to rebook you on another airline

Whether an airline must put you on a rival carrier after a cancellation depends on where you are flying. On flights covered by EU261 or the UK’s version of it, the airline owes you re-routing “at the earliest opportunity”, and the UK Civil Aviation Authority says that can mean another airline if it gets you there significantly sooner. In the United States no federal rule forces an airline to buy you a seat elsewhere; what you get depends on its own contract of carriage and the commitments it has published. Know which system you are under before you reach the desk.

What EU261 and UK261 require

When a flight covered by EU or UK rules is cancelled, the airline must offer you a one-time choice between a refund, re-routing at the earliest opportunity, or re-routing at a later date that suits you. That is how the European Commission’s Your Europe guide puts it, and it adds a warning: once you pick one of the three, you lose your rights to the other two.

The rules cover every flight departing the EU, flights arriving in the EU on an EU airline, and flights to and from Iceland, Norway and Switzerland. UK law, according to the CAA, covers flights departing the UK on any airline, arriving in the UK on a UK or EU airline, and arriving in the EU on a UK airline.

Compensation is a separate question. If you were told of the cancellation less than 14 days before departure, you may also be owed €250, €400 or €600 (£220, £350 or £520 in the UK), unless the cause was an extraordinary circumstance such as severe weather or an air traffic control decision. Our guide to what airlines owe you for delays and cancellations covers those amounts in full.

When the airline should book you on a rival carrier

“Earliest opportunity” is not the same as “the airline’s next flight”, and the UK regulator says so. On its cancellations page the CAA writes that although most airlines rebook you on another of their own flights, if an alternative airline is flying there significantly sooner, or other suitable transport is available, you may have the right to be booked onto it. It tells passengers to raise this with the airline.

That is the sentence to have ready. If the airline’s own next seat is two days away and a partner or rival leaves tonight, you are not asking for a favour. You are asking it to meet its obligation to get you there at the earliest opportunity, on comparable terms.

Airlines resist this because buying you a seat on another carrier costs them far more than waiting for space on their own planes. Expect pushback, especially during mass disruption. Stay polite, name the specific flight you have found, and ask the agent to note your request on the booking if they refuse.

What happens on US flights

On a US flight there is no federal requirement to put you on another airline; what you are owed is a refund if you decline the rebooking, and whatever the airline’s own contract promises. The Department of Transportation’s refund rule, 14 CFR Part 260, requires a refund when a flight is cancelled or significantly changed and you do not accept the alternative. “Significantly” means departing or arriving three hours or more off schedule on a domestic trip and six hours or more on an international one, a different airport, or more connections.

Contracts vary, so read your airline’s. Delta’s domestic contract of carriage, for example, says that after a cancellation it will carry you on its next Delta flight with seats in the class you bought, and that at its sole discretion, and if you accept, it may arrange travel on another carrier or by ground transport. That is permission, not a promise.

The DOT publishes an Airline Customer Service Dashboard showing, airline by airline, which services each has committed to when a delay or cancellation was within its control, including whether it will rebook you on a partner or another airline at no extra cost. Look up your carrier before you fly, and quote the commitment if it applies.

What to say at the desk or on the phone

Arrive with an alternative already found, the rule that applies to your flight, and a clear request. Agents rebook fastest when you hand them a specific flight number.

Try more than one channel at once. The airline’s app, the phone line and the desk often work from the same inventory but at different speeds, and during a mass cancellation the first person to ask gets the scarce seats on the partner flight.

If you are flying to Nepal

A cancelled long-haul connection is the likeliest thing to cost you the first day of a trek, so land in Kathmandu with a spare day before it starts. Most routes to Nepal connect through a Gulf, Indian or Southeast Asian hub, and a cancellation there can reroute you through a different city altogether. A spare day turns that from a missed trek start into a late dinner in Thamel.

If your flight is cancelled on the way, send your trek operator the new arrival time as soon as you have it. We shift start dates regularly when we are told early. For cover beyond what the airline owes, read what trip delay and missed-connection insurance actually pays, and when the cause is outside the airline’s control, what airlines owe you when air traffic control fails.
