TWA is the word....the ONLY US airline that shows its care for students as far as discounts go. For $548, you can get a book of 4 one way coupons valid for travel within the 48 US ( AK and HI require 2 coupons each way), Mexico, and the Carribean. These tickets DO earn frequent flyer mileage and are upgradeable using TWA elite status only...all travel must be booked in T class at least 14 days prior OR you can standby on day of flight if you aren't ticketed so it definately beats the Y fares.
