Like all airlines those at the top are happy and those at the bottom are not.
-Not everyone is home every night. If you are on the bottom 1/3 of some bases you could be sent TDY for your monthly bid.
-TDY may have you on reserve where you will have only 10 days off to commute home.
-Some reserve lines start the first day at 4am and shift to pm trips that end the last day at 10pm... effectively taking another day off away.
-Entire bases open and close with little notice. While we understand that an unprofitable base is just that, it still stops those who live there from being home nightly.
-Aside from monthly TDY, you may get a phone call to be at another base for a few days to cover trips on reserve. You will not be given a rental car and you will get $1/hr per diem. This phone call can and does happen often on reserve.
If you asked a senior 777 captain what life is like at American you'll likely get a different response than a reserve LGA MD80 FO. Yet you don't ask a senior 777 captain what life is like at American, you ask the FO if you are planning to apply. I suggest you do the same in regards to Allegiant. I am senior here and life is good, but have seen friends upgrade and then downgrade because being junior here is so bad.
