Question,
I have an AT ticket and traveling with friends who both have SW tickets. We are all on same AT flight. I purchased advance seat for myself both ways since I had a credit I had to use. They will go on 24 hrs in advance to check in.

So 1st. PHL-FLL. I assume we all go to AT to check in so their bags go on the correct flight? I "think" different terminals at PHL.

2nd..also how can I work it so we can all sit together? Girls week trip and obviously want to be together..

Thanks for all the help
