After watching and hearing a bunch of kids run around, scream, throw balls against the window of the airport, and cough, I asked if I could use my $50 in vouchers to upgrade to business class. The woman said that I couldn't use them to upgrade; they had to be called in. I thanked her and said that I'd spent the night at Disney World with my grandkids and couldn't put it on my card, and
Upgraded me for free.
I love Airtran.
