Check-in and bag drop close 45 minutes before most U.S. flights
By the TSA Wait Times team · Updated · Published June 2026
That's the cutoff almost no one plans around: at most U.S. airlines, check-in and bag drop close 45 minutes before a domestic flight and 60 minutes before an international one. Miss it and you can be turned away at the counter with a paid ticket in hand. Here's every airline's cutoff, what changed in 2025, and how to build the deadline into the exact time to leave home.
Check-in and bag-drop cutoffs by airline
These are each airline's published cutoffs as of June 2026. Airlines revise them and some airports run stricter deadlines, so confirm yours before you fly:
| Airline | Domestic bag drop | International | Gate |
|---|---|---|---|
| Delta | 45 min | 60 min | 15 min |
| United | 45 min | 60 min | 15 min |
| American | 45 min | 60 min | 15 min |
| Southwest | 45 min | 60 min | ~10 min |
| JetBlue | 45–60 min | 60 min | ~15 min |
| Alaska | 50 min | 60 min | 30 min |
| Frontier | 60 min | 60 min | 20 min |
The “Gate” column is how long before departure the boarding door closes — a second, later deadline (see below). Spirit Airlines is not listed: it ceased operations in May 2026.
What changed in 2025
The big carriers spent 2025 tightening and lining up their deadlines — the reason a cutoff you remember from a few years ago may now be earlier:
- Delta moved its domestic checked-bag cutoff to 45 minutes on April 8, 2025.
- United aligned its no-bag domestic check-in to 45 minutes on June 3, 2025, up from 30.
- Frontier moved its counters to 60 minutes on August 16, 2025, up from 45.
- Americanwas already at 45 minutes and didn't change — handy, because it makes 45 the number to remember for the big three.
Two clocks: the counter and the gate
There are really two deadlines, and people miss flights by confusing them:
- The counter — check-in and bag drop close 45 minutes out (60 international). This is your earliest hard wall if you have a bag.
- The gate— the boarding door closes about 15 minutes before departure on a domestic flight, and 30 on an international one. Being in the terminal isn't the same as being at the gate.
With only a carry-on you can skip the counter, but not the gate — and you still need a boarding pass before you reach security. For the full international picture, see how early for an international flight.
Build the cutoff into your Leave-By Time
Here's the step that turns a missed-flight story into a calm morning: count backward from the earlierof the two deadlines — the bag-drop cutoff and the gate close — not from departure. Then add the part that actually moves: today's live security wait, plus your drive and parking.
The Leave-By Time calculator does this stack for you — it folds the cutoff, the live wait at your airport, your drive, and the walk to the gate into one time to leave home. Flying from a big hub like Atlanta (ATL)? Check today's security wait first, because that's the number that decides whether 45 minutes of slack is plenty or not enough. And if you're still weighing the whole window, start with how early to get to the airport.
A few more questions about cutoffs:
When does airline check-in close?
At most U.S. airlines, check-in closes 45 minutes before a domestic flight and 60 minutes before an international one. A few airlines run longer cutoffs — Alaska is 50 minutes, Frontier is 60 — so confirm yours before you go.
What time does bag drop close before a flight?
Bag drop closes 45 minutes before departure for most domestic flights and 60 minutes for international. This is the hard deadline: reach the counter after it closes and the airline can refuse your bag, even if you make the plane.
Can I still board if I miss the bag-drop cutoff?
Sometimes, if you drop the bag and ditch nothing — but the airline isn't required to take you. Missing the cutoff is the most common way people are denied boarding with a valid ticket, so treat it as a firm wall, not a suggestion.
Do the cutoff times change if I don't check a bag?
Often yes. With only a carry-on, Delta lets you check in as late as 30 minutes before a domestic flight, while United and American hold you to 45. You still need a boarding pass and have to be at the gate before it closes.
Did airlines change their check-in cutoffs in 2025?
Yes. Delta moved its domestic bag-drop cutoff to 45 minutes on April 8, 2025, United aligned its no-bag domestic cutoff to 45 minutes on June 3, 2025, and Frontier moved counters to 60 minutes on August 16, 2025. The trend is toward earlier, stricter deadlines.

Keep planning
Flight day
How early should you get to the airport?
Two hours domestic, three international — then let today's real security wait and your drive set the exact time to leave.
Flight dayHow early for an international flight?
Three hours is the rule of thumb — but the 60-minute check-in cutoff and today's live wait set your real time to leave.
Flight dayMinimum connection time, by hub
The shortest layover an airline will book — about 35 minutes domestic, two hours-plus international. Check yours before you cut it close.
