Hi - my husband has been sent to Germany for work for 3 months. I am trying to find an economical way to fly there around August 14th to spend a couple weeks with him and come home around August 30th. If I search Dayton to Frankfurt round trip I come up with US Airways flights for about $1625 that fly thru Philly. BUT...I found that Philly has a SUPER $825 US Airways r/t to FRA flight once a day as a gateway airport. I can fly DAY to PHL for $250....SO....is there any reason I can't book TWO tickets and save all this money??? This would be $1075 plus some extra baggage fees if my credit card doesn't help me but I think I can get one free bag. Someone told me this was called "nesting" and that I may not be allowed to do it...why? I called US Airways and they just kept quoting me the same $1625 rate... Thanks!
