American Trans Air announced yesterday that it’s introducing an elite level to its frequent flyer program.

Information in the press release and on the ATA website is still a little sketchy. ATA is starting to offer business class seating. The elite level doesn’t specify anything about upgrades, just “preferred, front-of-aircraft seating.” But it’s a promising start.

ATA joins Airtran in offering both business class and an elite frequent flyer program, further eroding the differences between the major carriers and the discounters. And frequent flyers who follow a contrarian strategy, seeking upgrades where the lines are shorter, should keep an eye out for further developments with this one.
