I was booked PHL-DFW-ZRH for May 3. I also was thinking why fly to DFW when I can fly out of JFK. So I ade a reservation for that. After thinking about which flight to take, I decided to fly out of PHL, cause the last two times that I travelled to JFK it was hell getting there and back. So I cancelled my JFK reservation and went into my other reservation to book it. The computer cancelled it out. I was never informed that they were going to do this and if I would have known I would of simply booked that right then. But I was just exploring my options and they cancelled it on me. Then I went back and try to book the JFK flight but it doesn't let me choose my seats and I do not want to sit next to the crapper in 42C. I called the number up and they wanted to charge me $15 for booking it by phone. I asked them to give me a seat not near the crapper. Is there anyway possible that I can get my origininal reservation reinstated? I hope so. I also had to confirm with my employer that the dates that I was gone would be OK.
