I'm currently pounding on what I like to call "Dinner & a movie". Fact is that me and my partner are airplane crazy and love flying, and since we are able to fly almost for free we are now planning to fly from Europe to ORD and immediately fly back. Yeah, you read that right Of course only if premium seats are available.

Previous years we did this durng Christmas holiday but always booked a night to stay and visi the city.But now we happen to only have time to fly back immediately

The question that I have is: is it possible to leave the plane and stay at the gate for boarding again or is it really necessary to go full circle along border control? I suspect the latter as one could decide to leave the secure area through anoher way and as such enter the US without passing border control.
