A passport is only required for international flight other otherwise all you need is just your valid ID and proof of who you are and you can get on and fly anywhere inside of America without a passport. I live in Alaska and I don't need a passport to come down to the lower 48
No need for domestic travel.
No. But you do need valid ID
As long as you are an American citizen and have a valid drivers license and or state ID then no, but if your visiting or been here from another country then u will need everything you needed to fly in the states and get through customs. There will not be a customs check point but when u fly out they will check your ID/ passport just like everywhere else. No one can fly without ID or passport unless your under age. I don't know the process for under age flying though. So citizen just need state ID or Drivers license. Non citizen passport / visa and so on.
