Hi, Nancy! I was hoping you'd chime in. I really miss Air Tran, too. I don't mind Frontier, but I wish they had nonstop more days of the week.
Have you been watching prices? We flew BMI to SFB (Sanford) this July for $533 including two checked bags on Allegient. I was thrilled with $177 per person. I just don't know if I want to pay $169 more for January flights.
Since AirTran pulled out of BMI - I flew to Orlando on AirTran from Indianapolis in July with 2 of my kids. I found a cheap non-stop from Chicago O'Hare on American for next week (hope my flights don't get cancelled!), and I'll fly on Delta from BMI in December. Thanks for the info about Allegient and Frontier. I'll look into them for future trips.
