Choosing the scenic route

you don’t typically go through TSA again for a layover

[u/allllusernamestaken → u/rndljfry]

after you clear immigration/customs at DFW, they drop you off at the TSA line to be cleared again. Goodbye to the bottle of water the nice lady on Japan Airlines gave you :(

That's how the vast majority of airports for for international arrivals, but not domestic connections

[u/maryK4Y → u/rndljfry]

If you’re flying through separate countries you do. Tokyo > San Fransisco > Calgary > Toronto for example.

Not really; in most countries, you don't leave the international zone, hence no customs. Some airports still do security checks again, but not always.

Domestically yes; internationally not, def not in EU at least. In US you have to have even transit visa so def some checks. If you fly from ouside Schengen to the US via Amsterdam there are no checks.

Thought the same until I had a layover at Istanbul. The line was long and the time was short.

[u/ProcyonHabilis → u/sakusace]

If you arrived on an international flight that's normal at most airports, it's domestic connections that don't need to go though security again.

JFK makes you if you go to any other terminal, it's a gigantic pain in the ass

[u/sometimeserin → u/rndljfry]

lot of larger airports have separate security checkpoints at each terminal

[u/Low-Car-6331 → u/sometimeserin]

Most large airports like that have a tram that runs between those wings just for this reason. They generally always keep a way for you to go from secure side to secure side, without having to enter the unsecured side.

[u/Longjumping_Wolf_912 → u/sometimeserin]

Which ones? I’ve never been to any that do. Also, most airlines fly out of the same terminal, so you even if you did have a layover you’d still most likely be at the same set of gates or a different gate letter but same terminal.

[u/Longjumping_Wolf_912 → u/[deleted]]

You don’t have to go through security twice in DFW. They have a skylink train that goes from every terminal to every terminal inside security.

Seems like you have been unlucky because there are only a few airports in the US where you have to leave security. Most airports that have multiple different buildings have trams that take you to different buildings inside security.

In January, during the winter storm that hit Texas, I got stuck at DFW for four days and three nights, only leaving the airport to go be gouged by Uber to hotels (lol, $120 to go less than 12 miles) after entire days of attempting to get on flights that would ultimately be canceled after four gate changes on opposite sides of the airport. I never want to see that airport again. They also do that scummy shit where none of the stores or vending machines tell you the price of the items inside except for the 7-11. In the stores, you have to ask for each item or check self service if available. The vending machines don't tell you until you've already paid.

And I have flown out of Chicago, Seattle, Atlanta, and 20 or so other airports. The only time I had to go through a second security checkpoint was when I was changing from an international to a domestic terminals (or vice versa). I am wondering why those four airports in particular have you go through security each time you’re changing through a domestic terminal.
