I and my spouse are planning to be in the US for 3 weeks in May-June. We havent come up with exact plans for places to visit and how long etc... But it is most likely to be the east coast attractions - Orlando/DC/NY/New England. And Chicago Any suggestions for cheap and efficient domestic travel in the US? Is there a fly-as-much-as-you-can monthly ticket sold by any of the airlines or alliances? I do remember the story of a guy who bought one from a US airline and flew around for a month or so... Or should I just buy regular tickets for each trip? Thanks.
