TTN - TPA

TTN is a small airport for Frontier. Drop off is easy as is parking. The location is remote so there is zero traffic. The place could use a renovation but for the price you pay it is not necessary. Good-Staff is very friendly. Flight left on time. Bad- run down, deplaning/boarding on the tarmac. I got wet on the stairs outside of the plane while waiting to board.
