Scenario
My gate changed and I'm on the other side of the airport: what to do
Short answer: confirm the new gate on the airport's departure screens, check when the gate closes (often 15 minutes before departure), and start moving straight away. Take the airside train if the airport has one.
If the new gate is in another terminal that isn't joined inside security, you may have to go through security again. If you can see you won't make it, tell the airline before the gate closes, not after.
You've found a seat, a coffee and a charger at the far end of the terminal, and then the board flips: your flight now leaves from a gate a train ride away. Here's what to do, in the order you'd do it.
1Check the change is real, and check the time too
Look at the nearest departure screen or listen for the announcement. The airport's own screens and the gate staff have the final word. If an app and the screen disagree, go with the screen and ask a staff member.
While you're looking, check the departure time, not just the gate. Gates often change for the same reasons flights run late: the plane at your gate hasn't left yet, your aircraft has been swapped for a different type, or there's a mechanical problem. A new gate and a new time often show up together.
2Count back from when the gate closes
The deadline that matters isn't the departure time. It's when boarding closes. Delta, for example, requires you to be at the gate and ready to board 15 minutes before departure, and can give your seat away if you're not. Other airlines set their own cutoffs, and your boarding pass or airline app usually shows the boarding time.
So if your flight leaves at 10:00, treat 9:45 as the real finish line. How long you have is 9:45 minus the time now. That number decides how fast you need to go.
3Work out how far it really is
A "new gate" can mean a two-minute walk or a whole new terminal. The signs above the walkways tell you which kind you're dealing with.
| Where the new gate is | How you get there |
|---|---|
| Same concourse | Walk. Use the moving walkways. |
| Another concourse, joined inside security | Take the airside train if there is one. At Dallas/Fort Worth, Skylink runs inside security, arrives every 2 minutes and takes 9 minutes at most end to end. |
| Another terminal, not joined inside security | You leave security and are screened again at the new terminal. At JFK, that means the AirTrain, then TSA again. |
If you're not sure which applies, ask any airport or airline staff member. It's a 10-second question, and it's quicker than walking the wrong way.
4Go now, and don't stop on the way
Leave the coffee queue, pack your charger and start walking. If the train is there, take it; if the next one is a couple of minutes away, it's usually still faster than walking between concourses at a big hub. Keep your boarding pass ready, and keep checking the screens as you pass them. Gates sometimes change more than once.
5If you won't make it, say so before the gate closes
If the sums in step 2 don't work, contact the airline before the deadline. Use its app or chat, or call, or tell any of its agents you pass. If the flight turns out to be delayed, you may make it after all. If not, you're in the queue for the next one sooner, rather than arriving at a closed door and starting from scratch.
So a gate change doesn't catch you out
- Note your boarding time and when the gate closes, not just the departure time
- Stay within earshot of announcements, or near a screen, once boarding is close
- Don't settle far from your gate in the last 45 minutes or so
- Know whether your airport has an airside train between concourses
- Turn on alerts for your flight, so the change reaches your phone
Gate deadlines differ by airline, airport and route, and an app can lag behind the airport's own screens. Always go by the departure screens and the airline's staff, and check your airline's boarding cutoff for your flight.
Questions people ask
Will the plane wait for me if the gate changed?
Don't count on it. A gate change doesn't usually move the gate deadline, so the airline can still close boarding and give your seat away once it passes. If you can see you'll be late, tell the airline before the deadline rather than after.
Does a gate change mean my flight is delayed?
Not always, but the two often go together. Gates commonly change because the plane at your gate hasn't left yet, your aircraft was swapped, or there's a mechanical problem. Check the departure time on the screen as well as the gate.
Why don't airports show the gate until shortly before boarding?
Because it can still change. Airlines finalise gates on the day of departure, and late-running planes keep shuffling them, so some airports hold the number back until it's unlikely to move.
Can I go through security again if the new gate is in another terminal?
At airports where terminals aren't joined airside, you'll have to. At JFK, for example, changing terminals means taking the AirTrain and being screened by TSA again at the new terminal, so allow extra time.
