"No real roster stability and endless calls to work on your day off without any compensation except getting the day off back at some stage."
that comes in the package dosent it ? that is still not so bad.. even some LCC (Low Cheapskate Carrier
) will ask you to change aircraft and continue to fly few more sectors even coming back with a single engine or even from a decomp. (only half of the masks dropped in the cabin !)
at the end of the day, a LCC is a LCC, goto a national airline or a non LCC. just my 2 cents.
