Q. There was a time when you could buy a ticket and it was good for several months to a year.  Are those available anymore?  Also AirTran use to have a promo…buy 6 tickets, get one free trip.  I assume this went out the window as well?

A. The only fares I know like that are fully refundable ones which tend to be the most expensive. And even those aren't entirely free of restrictions.

As for Airtran, they still offer a free roundtrip after 3 business class  or four economy class roundtrips.
