I suppose what can be said about this is that overnights and allowances are not, and cannot be guaranteed as part of your income. We discovered that very quickly in 2004 in the change over from Impulse/Qantaslink to Jetstar. One month we were getting 8-10 overnights a month and the next month none......gone forever!
Management have seen what savings can be made by eliminating/reducing overnights at Jetstar, lets hope you guys dont suffer like we did.
