We had a guy who posted here a few weeks ago who was stuck in Europe for over a week with his wife and children because he had flown over on buddy passes and couldn't get back because flights were full. He was hopping all over the place to try and get back to DC, spending loads on hotels and probably coming close to a divorce. We never did hear how/if he got back, but in the end it probably would have been cheaper for him to have bought economy tickets outright! Just beware!
