Update: Flew on Frontier row 12 yesterday. Absolutely LOVED IT! I thought it had more legroom than the stretch seats in the first couple of rows (stretch seats were $50, row 12 was $16 on our flight). Note: tray tables are in the arm rest of the seat. If I ever fly Frontier again, it's going to be in row 12. Economy priced seating for first class legroom. Check.
