If an airline gives your flight a new number and puts you on it, you are not owed an automatic refund. The federal government has now extended that position by another year.
The Department of Transportation published a notice of enforcement discretion on July 7, 2026, stating that it is extending its pause on enforcing the refund requirements for cancelled flights under 14 CFR parts 260 and 399 where a flight is “merely renumbered”. The extension runs one year from publication and expires on July 7, 2027.
- July 7, 2027: the date the enforcement pause expires.
- What is paused: refund enforcement when a flight is only renumbered and you are rebooked on it.
- What still applies: refunds for a significant change or delay, and for a genuine cancellation.
- Still pending: the Refund III rulemaking, RIN 2105-AF36.
What the Pause Actually Covers
The pause is narrow and conditional. It applies when a flight is given a different number and the passenger is successfully rebooked on that new flight without experiencing what the rules call a significant change or delay.
Miss any part of that and the pause does not apply. A renumbered flight you were never rebooked on is not covered, and neither is one that moved enough to cross the thresholds below.
The Test Is Significant Change, Not the Flight Number
The department’s own consumer page sets out what counts: a departure three or more hours earlier on a domestic flight or six or more on an international one, an arrival three or more hours later domestically or six or more internationally, a different origin or destination airport, an added connection, or an involuntary downgrade to a lower class of service.
Passengers with disabilities have two more triggers, a change of connecting airport and the loss of an accessibility feature on the aircraft. Any one of these is enough on its own.
When a Refund Is Still Owed
A cancelled flight still entitles you to a refund regardless of the reason, if you decline the alternative the airline offers and choose not to travel. That has not changed and is not part of the pause.
The payment clock has not changed either. A refund is due within seven business days if you paid by credit card, and within twenty calendar days for any other form of payment.
The Consumer Page and the Enforcement Position Differ
Here is the part worth knowing before you argue with an airline. The department’s public refunds page describes cancellations and significant changes and says nothing at all about flight renumbering.
So the page a traveller reads and the position the department is currently enforcing are not the same document. Quoting the consumer page at a gate agent will not produce a refund the department has said it will not pursue.
Planning Around a Rule in Motion
The practical move is to measure the change rather than the number. Compare your new departure and arrival times against the originals, check the airports and the connection count, and look at your fare class.
If any threshold is crossed, the refund right is intact and worth pursuing in writing. If none is, the renumbering alone will not carry a claim before July 2027. Our guide to what to do when a flight is cancelled covers the steps that do work, and the airline change fees rundown covers the costs that apply when you are the one making the change.
| If your flight… | What to do |
|---|---|
| Was renumbered and you were rebooked on it | No automatic refund is being enforced until July 7, 2027. |
| Now departs 3 or more hours earlier, domestic | That is a significant change. The refund right applies. |
| Now arrives 6 or more hours later, international | That is a significant change. The refund right applies. |
| Was cancelled outright | Decline the alternative and a refund is due, whatever the reason. |
| Refund was agreed but has not arrived | Seven business days by card, twenty calendar days otherwise. |
A year, not a permanent change. The pause expires July 7, 2027 unless the rulemaking replaces it.
Measure the change, not the number. The thresholds are what decide a refund.
The public page is incomplete. It does not mention renumbering at all.
Do I get a refund if my airline changes my flight number?
Not automatically. If you are rebooked on the renumbered flight with no significant change or delay, the department is not enforcing a refund requirement until July 7, 2027.
What counts as a significant change?
Departing 3 or more hours earlier or arriving 3 or more hours later on a domestic flight, 6 hours either way internationally, a different airport, an added connection, or an involuntary downgrade.
When does the pause end?
July 7, 2027, one year from the July 7, 2026 notice, unless the pending Refund III rulemaking changes the position first.
Does this affect cancelled flights?
No. A cancelled flight still carries a refund right if you decline the alternative offered and choose not to travel.
How fast must an airline pay a refund?
Within seven business days for a credit card purchase, and within twenty calendar days for other payment methods.
Why does the DOT consumer page not mention renumbering?
The page sets out the underlying rules on cancellations and significant changes. The renumbering position sits in a separate enforcement notice, which is why the two read differently.
