Miss so far
1) Business Class upgrades
2) Atlanta centric direct options
3) Airtran chosen Snacks in BC such as Milano cookies, shortbread cookies , and the kettle chips. Not to mention the FUJI water.
4) Exit row assignments for elites. And even for non elites, it is cheaper than paying $40 for EBCI.
5) Competence by the customer service and the discretion/freebies some AirTran agents used to give you.
