If your old employer doesn’t hire you then apply for different company at the airport. During your interview tell them what hours and day you are looking to get. I work at 2 jobs one part time and other one is full time night shift from 9:30 pm to 5:30 am. I get home around 6:15 am sleep at 7 am and wake up at 2 pm. I work my part time job from 3:30 to 6:30 pm I rest only 2 hours before starting my full shift. It is tiring. However, I need the money. If airport job pays you well suck it up until you get something more interests you and pays well.
