Hello to everyone. I am flying to PHF on November 20, and I want to leave out of ISP. I want to Go from ISP-BWI on WN in the morning (I already know that I'm flying on flight # 943). Than I want to go from BWI-ATL, first class. From ATL, I want to go to PHF.
Also, If I book it on Expedia.com, will I be able to pick my own seats, and check-in online on the airline's website, because I don't want to have to Check-in at BWI and ATL, as I would just like to walk to the gate from my previous flights.
