IAD-FRA-IST-FRA-BOS
This is the itinerary that I will be flying over the summer. IAD-FRA-IST-FRA-BOS.
I have found a consolidator fare of $750 for a roundtrip flight from IAD to IST over the summer. However when I return, I want to return to boston, but if I route my ticket that way it would cost much more. Do you think it would be possible for me to purchase this round trip ticket and later change the return leg to bos instead of IAD?
