Here is my problem. I bought a really good fare on Expedia from Frankfurt, Germany to Seattle, WA for the 2nd of September. The same flight is now over a $100 more than a week ago than when I purchased it. However, I would like to go home earlier than the 2nd but still not pay more (or not much more) to do so. Is there a web site or somewhere that one can swap tickets with another person? Can you do that through the airline? I wouldn't be willing to pay more than say $150 to do that. I tried contact Expedia but it won't work on my phone here in Germany. Please help =(
