jaarrgh,
Thanks for the warning. Everyone should read your warning and INSIST on getting the aircraft type in writing with no strings attached - or just don't go... If they won't agree, don't move. The labor shortage will hit the ME hard in the coming years as the legacies return to hiring mode and experienced pilots stay where they are...
We call that BAIT and SWITCH where I come from. Even after moving I would still probably leave as a result of that switch.
