Days off
Odguy there is very little chance of getting more then 3 days off in a row. I have a friend who is a F/O on the 320, he bids for days off and the best he has had in 3 years has been 3 days in a row one time. If you are on the 320 you will be working or sleeping.
I am on the 777 and my roster is a joke, it is one of the worst things with QR. It seems the company will do their best to keep your days off to a minimum in a row. They know that's what you want so you can get out of lovely Doha so they always try to give you 2 days max.
But they guys on the 320 have it a lot worse then me.
If you're in your 20s, single, and this is your first jet job I'm sure you will enjoy it. But if you have a family and enjoy spending time with them you might not.
