Yeah a lot of people say the same......4000-6000 gross a month as F/O is normal I accept. But do the maths.....you are paid for scheduled block time.
You're not paid a penny for the 1 month off and the extra 10 ad hoc days off. You're not paid a penny for the 4 days off after working 5 on.
you can easily do 12 hours if you're in the crew room at 4.30 to be off block at 6....but you land at 3 and leave the crewroom at 4. It's often about 12 hours 5 days a week which means your working 60 hours a week.
Now you have no pension which is huge, also if you break your leg skiing you won't get a penny until it mends. If you get diabetes you'll never see another check.
You can have private loss of license and pension but if you take the price away from your 4200 you'll have nothing left.
