Every departed U.S. domestic flight in the past 12 months whose final departure delay reached your number (Washington Reagan National (DCA)). BTS records the final delay only, so flights announced late that then recovered aren't counted; treat this as a guide, not a forecast.
How delays grow
A small delay usually stays small: of flights that left at least 15 minutes late from DCA, 46% got away within another half hour. Once a flight is an hour late, the odds turn. 63% of those waited at least 30 more minutes and 43% another full hour, because a delay that long usually means a missing plane, crew or air-traffic slot, not slow boarding.

Watch the plane you're waiting for
Airline apps usually show where your plane is coming from ("Where's my plane?"). It is the best clue you have: how late that plane lands sets how late you leave, and a cancelled inbound flight is the most common lead-in to a cancellation.
| Inbound plane | Flights | Yours left 15+ min late | Typical departure | Yours cancelled |
|---|---|---|---|---|
| Landed on time | 82,940 | 15% | on time | 0.5% |
| 15–29 min late | 9,969 | 49% | 14 min late | 1.1% |
| 30–59 min late | 9,382 | 79% | 33 min late | 1.7% |
| 60–89 min late | 4,245 | 91% | 62 min late | 2.4% |
| 90–119 min late | 2,219 | 91% | 90 min late | 2.5% |
| 120–179 min late | 2,209 | 90% | 124 min late | 4.4% |
| 180–239 min late | 967 | 88% | 174 min late | 7.0% |
| 240+ min late | 1,011 | 81% | 192 min late | 20.3% |
| Its previous flight cancelled | 2,273 | 55% | 24 min late | 64.4% |
Inbound = the same aircraft's previous flight that day (matched by tail number) landing at this flight's departure airport.
What to do, in order
- Find your backup before you need it. Search the airline app for the next flights to your destination now. Agents rebook in the order people ask, and the app is faster than the line.
- Check the inbound plane. If it hasn't left its last airport, your delay will grow. If its flight is cancelled, ask whether another aircraft is assigned.
- Mind the 3-hour mark. At 3 hours, a domestic delay entitles you to a refund if you choose not to fly. Don't take a voucher instead unless you want one. Your rights, in full →
- Connecting? Compare your layover with the typical extra wait above, and check the connection. If you'll miss it, ask to be rebooked to your final destination before you board.
- Late evening? If yours is the last flight of the day and it's cancelled, the next one is usually the morning. Ask for a hotel if the cause is the airline's (crew, maintenance) rather than weather.

Questions
If my flight is delayed an hour, how much longer will it be?
At Washington Reagan National (DCA), half of flights already an hour late left within 48 more minutes. 43% were delayed at least another hour and 21% at least two more, based on every departed flight in the 12 months to August 2026.
Does a long delay mean my flight will be cancelled?
Usually not. The strongest warning sign is the plane you're waiting for: when its previous flight was cancelled, 64% of the flights waiting on it were cancelled too, against 4.0% of flights overall. When the inbound plane was 4+ hours late, 20% were cancelled.
Am I owed anything if my flight is delayed?
In the U.S. there is no cash compensation for delays. If a domestic flight is delayed 3 hours or more and you choose not to travel, you are entitled to a refund of the ticket. Most large airlines also commit to meal vouchers, and hotels for overnight delays, when the cause is within their control.
Are evening delays worse?
An hour-late evening flight slipped another hour 43% of the time, against 44% before noon; morning delays grow more often, but there are far fewer of them. In the evening, 56% of delay minutes come from late-arriving aircraft, which stack up through the day.
Every departed domestic flight from DCA in the 12 months to August 2026 (BTS). "Delayed at least X" uses each flight's final departure delay, since BTS doesn't record what passengers were told along the way. These are past patterns, not a forecast for today: on a stormy day every number here is worse. Method.
