What a great country - we have a choice. If you don't like FL - don't fly them. Thats one more seat for everybody else.
But don't compare Airtran to Delta - two different airlines, two different operations. If you don't like Delta - fly airtran, give up those unlimited free drinks in first class and membership to the crown room - its too crowded anyhow when people bring in 4 freeloading guests.
