Change & Update Guide
What Happens When an Airline Changes Your Schedule
An email arrives saying your flight time has moved. Whether that is trivial or valuable depends entirely on how many minutes moved.

Airlines republish their schedules constantly. Aircraft get reassigned, slots move, a seasonal timetable replaces the last one, and a route that was 14:20 becomes 11:50. From the airline's side this is routine planning. From yours it can be an inconvenience, a missed connection, or an opening.
The key word is involuntary. You did not ask for this change, so the normal change fee logic does not apply. What applies instead is the carrier's schedule change policy, and in some regions, statutory passenger rights.
Thresholds by carrier
Every airline sets a threshold above which a schedule change is considered significant. Below it, you accept the new time or pay to change. Above it, you can normally request a rebooking or a refund at no charge.
| Airline | Threshold | Remedy usually available |
|---|---|---|
| Delta Air Lines | 90 minutes or more | Rebook free or refund |
| United Airlines | 30 minutes domestic, 2 hours international | Rebook free or refund |
| American Airlines | 4 hours | Refund on request |
| Lufthansa | 2 hours | Rebook or refund |
| British Airways | Any change causing a missed connection, or a large time shift | Rebook, refund considered case by case |
| Emirates | Varies by route and fare | Rebook, refund at discretion |
Cancellation of the flight is a different category
If the airline cancels outright rather than moving the time, you are into rerouting and, in some jurisdictions, compensation. Under EU Regulation 261/2004 and the retained UK version, a cancellation notified less than 14 days before departure can trigger a fixed cash payment on top of the refund or reroute, unless extraordinary circumstances apply.
A schedule change made months in advance does not attract that compensation. The 14 day boundary is the practical dividing line, and it catches people who confuse the two categories.
What to ask for, and in what order
01
Establish exactly what changed
Original time versus new time, in minutes. Also check whether the flight number, aircraft or routing changed, since a routing change can matter more than the clock.
02
Check the downstream damage
Connecting flights on separate tickets, trains, hotels, car hire, an event you are flying for. Document any cost that is now at risk.
03
Decide what outcome you actually want
A different flight the same day, a different day entirely, a different airport, or your money back. Ask for one thing clearly rather than presenting a list.
04
Quote the airline's own policy
One sentence. Your published policy treats a change of two hours or more as significant, and this change is three hours ten minutes.
05
Request rerouting on any available flight, not just their next one
Where the ticket is endorsable, rebooking onto a partner airline is possible. This is the single most valuable request most passengers never make.
06
Get it in writing before you accept
A new itinerary or a refund reference number. Verbal agreement disappears when the call ends.
The awkward middle ground
Changes of 30 to 90 minutes are the difficult zone. They sit below most thresholds but can still ruin an itinerary, particularly when a connection on a separate ticket is involved. Airlines are under no obligation here, so the approach has to be different.
- Explain the consequence rather than the inconvenience. A missed onward flight is a concrete problem, an earlier alarm clock is not.
- Ask for a same day alternative, which costs the airline nothing in inventory terms if seats are open.
- If you booked through an agency, escalate there first. Agencies have waiver codes for schedule change situations.
- Be quick. Options are widest the day the change is published and narrowest the week of departure.
A worked case
A traveler holds Madrid to Bogotá on Iberia, departing 12:05, connecting in Bogotá to a domestic Avianca flight to Cartagena booked separately. Iberia moves the Madrid departure to 15:40, arriving too late for the Avianca connection.
- The shift is three hours thirty five minutes, above Iberia's significant change threshold.
- Iberia's obligation covers its own ticket, not the separately booked Avianca sector.
- The productive request is a reroute onto an earlier Madrid departure, or via a partner such as Avianca's own Madrid service, preserving the original arrival window.
- If no reroute works, a full refund of the Iberia ticket is available, but that leaves the Avianca ticket stranded. Changing Avianca is usually cheaper than losing the whole trip.
- Travel insurance may cover the Avianca change under missed connection cover, but only if the policy does not require both flights on one ticket. Most do require that, which is the argument for single tickets on longhaul.
Frequently asked
Do I have to accept the alternative flight offered?
No. If the change exceeds the significant threshold you can normally decline and request a refund instead, or propose a different alternative. Declining does not waive your right to the refund.
The airline changed my aircraft type and my seat is gone. Any recourse?
Yes for the seat fee, which should be refunded if the equivalent seat is not available. The aircraft swap itself is not a compensable event.
How will I be notified?
Email or app notification to the contact details in the booking. If an agency made the booking, the airline notifies the agency, and some agencies are slow to pass it on. Check the airline app directly every few weeks for distant bookings.
Can a schedule change turn a non refundable ticket into a refundable one?
In effect, yes. Once the change exceeds the carrier's threshold the fare's non refundable condition is overridden, because the airline is no longer providing the service you bought.
