No forms to fill in, and when you get off the plane you walk through the boarding gates and into the main terminal, just follow signs for bag reclaim and head off to your destination.

Domestic arrivals are bliss in the USA.

ah right so its not different for international travellers? its just last time my husband only got a one time entry visa & as were thinking of flying while in the us on our next trip didnt wanna get turned away as weve allready entered once if you get me!

thats a point would we be able to board? say if we were in miami hes entered on a visa one entry which will have been used & we want to fly to another destinaton can we? oh this confuese me! lol

Thats not an issue because he wouldn't have left the USA. It's a totally different system for domestic travel in the USA which is more like getting a bus here in the UK. Basically you go to check in with your ticket (show your flight confirmation and ID, a passport for example) and then go through security (this takes time) and then get on the flight at the gate. After that, you have nothing to show, no documention, no passport etc. You just disembark into the gate, walk through to the terminal, pick up your bags and head off.
Very simple process.

Ah cool, thanks for that! At least now i dont have that to worry about.... lol.

No it really is easy to get around the states by plane,cheap to if you look around .
