Frontier has hired 24 in October and another 14 in January. Interviewing and hiring is still going on now. F9 has a bid out for 25 Boeing Capts. and 41 Airbus Capts. so there should be more hiring for the next few months.
Due a search on this board for Frontier, I have posted what F9 is looking for to give you a call.
F9 is a great place to work and is getting better. We are waiting to hear what UAL is going to due in the next few weeks, so right now little is being said at the office. Rumor has it that we will be in the black by spring.
Good luck in your endevors.
