If you fly within the state (let's say SF to LA), do you still need to show ID?
Or is the ID only used when you travel to another state? And do they check your ID when you arrive in another state, or is it only for departing?
I was under the impression there is no internal immigration controls between different states, but I also did hear that IDs are checked when flying.. so I want to know more about this!
Thank you! 😀
