and rebooking rights first, not direct disruption expenses.
Rights framework
Why this page is separate from the delay page
This page leads with the refund-or-rerouting choice the airline must normally offer
after a cancellation. Fixed compensation is shown as a secondary overlay because the
core cancellation question is usually whether you can recover the fare, reroute on a
comparable service, or reclaim the cost of a self-booked replacement flight.

Replacement-flight note
The airline should normally give you a refund-versus-rerouting choice rather than
simply cancelling and leaving you to solve the journey yourself.
A flight cancellation refund calculator should not begin with compensation. The first question after a cancellation is usually whether the airline must refund the fare, reroute you on comparable transport, or reimburse a replacement flight you had to book yourself because the airline failed to help. This page estimates the likely refund amount first, then layers in rerouting and cancellation-compensation rules under UK261 or EU261.
What this flight cancellation refund calculator is designed to answer
This page is built around the practical order in which cancellation rights usually matter. First, can you get your money back? Second, should the airline be offering rerouting instead of pushing you into a refund? Third, if you paid for a replacement journey yourself, is there a credible route to reclaiming that cost? Only after those questions does it move on to the fixed cancellation-compensation overlay.
That separation matters because passengers often mix together three different buckets: refund of the unused ticket, reimbursement of necessary replacement transport when the airline fails to reroute properly, and statutory compensation for inconvenience. A cancellation page should keep those buckets separate instead of letting one number pretend to answer every rights question.
Refund or rerouting: the airline normally has to give you a choice
Official UK guidance makes the core cancellation rule clear: if the airline cancels the flight, you are normally entitled to choose between a refund within 7 days or rerouting under comparable conditions. That is why this calculator always treats refund and rerouting as the primary result area. The legal structure is not 'take the refund and solve the rest yourself unless the airline feels generous'.
The choice matters because a cancellation can affect more than one fare component. If the cancelled flight was part of a larger reservation and the trip no longer serves its original purpose, the refund question may involve more than the single flight coupon that disappeared from the timetable. This page therefore distinguishes the cancelled-flight value from the full same-reservation booking cost.
When the whole reservation may matter, not just the cancelled sector
Refund disputes often become messy when the booking included an outbound and return journey on the same reservation. Official EU guidance notes that where outbound and return were part of a single reservation, an outbound cancellation can create rights affecting the whole ticket rather than just the cancelled leg. The practical issue is whether the cancelled flight means the overall trip no longer works for your original plan.
That is why this calculator asks whether there was a return leg on the same reservation and whether the cancellation made the whole trip pointless. If both are true, it estimates the refund basis using the full reservation value instead of only the cancelled-flight cost. That is still a screening estimate, not a guaranteed case outcome, but it is much closer to the real decision passengers face.
If the airline failed to reroute you, replacement-flight reimbursement can matter
A refund is not always the end of the story. EU guidance also explains that if the airline fails to comply with its obligation to offer rerouting under comparable transport conditions at the earliest opportunity, reimbursement of replacement flight costs can become relevant. That does not mean every self-booked itinerary is automatically recoverable, but it does mean passengers should not assume the original fare refund is the ceiling.
This page uses a separate field for self-booked replacement cost for exactly that reason. It does not fold that cost into the refund amount. Instead it flags the reimbursement question separately when you enter a self-booked replacement and indicate that no airline rerouting was offered.
Cancellation compensation is a separate overlay on top of refund rights
In addition to refund or rerouting rights, a cancelled flight may also trigger fixed compensation. Official UK guidance says this usually depends on three things: whether you were told less than 14 days before departure, whether extraordinary circumstances caused the cancellation, and what alternative flight timing was offered. That is why this page asks for the notice band, any replacement-flight timing differences, and the airline's extraordinary-circumstances position.
The fixed amounts track the same broad distance bands used elsewhere in UK261 and EU261. For UK261, that means 220, 350, or 520, with reduced outcomes in some rerouting scenarios. For EU261, the common headline bands are 250, 400, and 600 euros. These amounts are not the refund and they are not reimbursement of your personal replacement-travel cost. They are a separate statutory layer.
Likely refund amount = full same-reservation booking cost or cancelled-flight cost
The calculator uses the full reservation value only when the cancellation appears to have destroyed the purpose of the whole same-reservation trip.
Total potential cancellation compensation = fixed compensation per passenger x number of passengers
Compensation is screened separately from the refund amount and only after notice, rerouting, and extraordinary-circumstances conditions are checked.
Passengers sometimes focus so much on refunds that they forget the airline still has duties while they are stranded. The CAA states that airlines must provide care and assistance after cancellations, including food, communication, accommodation when needed, and transport to and from accommodation. Those rights matter even when compensation is later refused.
That is why this calculator shows care rights as a separate reading aid. A cancellation can produce a refund choice, a rerouting entitlement, and immediate support obligations at the airport all at the same time. One right does not cancel the others.
Worked examples: full-reservation refund and short-notice self-booked replacement
Suppose a same-reservation trip cost 860 in total, the cancelled outbound flight value was 430, and the cancellation made the whole trip pointless. In that scenario the stronger screening number is the full 860 reservation value rather than just the outbound sector. The passenger would still normally have a rerouting choice, but if they decline it because the trip is no longer useful, the full reservation may become the more relevant refund basis.
Now suppose a short-haul flight worth 520 is cancelled with less than 7 days' notice, no alternative is offered, and the passenger books a 280 replacement ticket themselves. The page keeps those numbers separate: 520 as the likely refund basis, 280 as a possible replacement-transport reimbursement question if the airline failed to reroute, and 220 per passenger as the likely fixed cancellation-compensation overlay if extraordinary circumstances do not block the claim.
What this calculator does not cover
This page does not decide package-holiday contract claims, insurer disputes, consequential losses, chargeback options, or the evidential strength of the airline's defence. It also does not guarantee that a self-booked replacement was the cheapest comparable option available, which can matter in real reimbursement disputes.
Use the result as a structured screening estimate only. If the core issue is compensation for a delayed arrival, use the flight delay compensation page instead. If the booking was a package holiday and the organiser's remedies are central, keep those package-contract rights distinct from the airline cancellation rights modelled here.
Frequently asked questions
Do I have to accept a refund when my flight is cancelled?
Usually no. The airline should normally offer you a choice between a refund and rerouting under comparable conditions. A cancellation does not usually let the airline impose a refund as the only solution unless the passenger accepts it.
How quickly should a cancelled flight refund be paid?
The official guidance points to a refund within 7 days. That timing applies to the refund route itself, even though disputes about extra costs or compensation can take longer.
Can I claim back the cost of a replacement flight I booked myself?
Potentially yes, especially if the airline failed to offer rerouting under comparable conditions at the earliest opportunity. The exact amount recoverable can still depend on whether the replacement was necessary and reasonable.
Does cancellation compensation depend on how much notice I got?
Yes. Notice timing is one of the main filters. A cancellation more than 14 days before departure usually does not trigger fixed compensation, while shorter-notice cancellations can do so unless the replacement timing fits the no-compensation safe-harbour or extraordinary circumstances apply.
If my outbound flight is cancelled, can the return flight matter for the refund?
Yes, if outbound and return were part of a single reservation and the cancellation means the overall journey no longer serves its original purpose. In that kind of case, the refund question can go beyond the single cancelled sector.
Do care rights still apply if the cancellation was caused by extraordinary circumstances?
Often yes. Extraordinary circumstances mainly affect the fixed compensation overlay. Refund, rerouting, and care rights can still remain relevant even when the airline says the cancellation was outside its control.
Should I use this page or a flight delay compensation calculator?
Use this page when the airline cancelled the flight and the main question is refund, rerouting, or replacement-flight reimbursement. Use the delay calculator when the flight still operated but arrived late and the main question is compensation for delay at the final destination.
What if the flight was part of a package holiday?
Airline rights can still matter, but a package organiser may also have its own duties and remedies. Keep the airline cancellation rights and the package-contract rights separate rather than assuming one number answers both.
