I have been scouting around for plane ticket from Fort Wayne to Frankfurt, or maybe Prague. My normal way is to get on Travelocity.com and search the fares for lowest available and my dates are open option. Than I call up a travel agent and book a ticket.
I also have a friend in Colorado that knows all the cheapest flights. He worked for an air courier organization and I would consider him a cheap flight expert. Nonetheless after I get on Travelocity.com, I know the price I am looking for.
