YourBestFlight › Flight delayed, what should I do?

Flight delayed? What to do right now.

Most "flight delayed" guides hand you a checklist. When you're standing at the gate, you don't need a to‑do list — you need the one flight that will actually get you there.

Short answer: Do two things. (1) Check whether the delay already crosses the U.S. DOT three‑hour mark — a domestic flight now scheduled to arrive at least three hours late (six hours international) can qualify as a "significant change," which lets you cancel for a refund if you'd rather not travel. (2) Instead of calling around, find the single replacement flight most likely to actually depart and get you there — judged on where the aircraft is now and realistic times, not the published schedule.

Why the times you're looking at are probably wrong

During a delay, airline apps and booking sites keep showing the originally scheduled times for a while. Those times drive which options look "best," so the flight the app pushes to the top may already be gone — and a genuinely better one is buried. The gap between the published time and the real, adjusted time is where the wrong decisions happen.

Example

Delta 1234, ATL → BOS. The app still lists a 6:10 PM departure. But the aircraft assigned to your flight is still on the ground in Miami and hasn't left; once you account for the inbound leg and the ground time the airline needs, the realistic departure is closer to 8:40 PM.

 PublishedAdjusted (realistic)
Departure6:10 PM8:40 PM
Arrival8:35 PM11:05 PM

A 2½‑hour gap. If you booked based on the 6:10 PM time, you'd make a bad call.

How YourBestFlight reaches a different result

Instead of trusting the schedule, YourBestFlight checks the things that actually decide whether a flight goes:

Then it ranks the alternatives by probability of getting you there and names the one to rebook — a decision, not a checklist. And if your delay already earns you a refund, it tells you and links you to the exact DOT rule.
