Hi there folks, I need some advice on how to efficiently handle arriving at Barcelona airport and immediately boarding another separate flight (not a connecting flight).

I'm going on a two week trip with some friends who will already be in Europe and I'm meeting them up in Barcelona, the end of my trip will have me leaving Paris back to Barcelona arriving at 8:35 AM.

My round trip flight from Barcelona back to the states takes off at 10:00 AM. So if not too much to ask other then waiting for my bag to come off the plane, would I need to exit out of the terminal and re-enter threw the main entrance to get myself ready for my flight back home?

The good part is both of my flights are in terminal 1, any advice that can be given is much appreciated.
