Just to share my agony. I left a perfectly healthy airline to Join QR on an offer of appointment as a PIC on the 777. I have wrapped up my house and got my kids out of school when BANG! three days before leaving I get an email that my fleet is changed to the A320!! I dont think this would happen in any other airline in the world! I have gone back to begging my previous employer to hire me and I think this is downright UNPROFESSIONAL. Either you dont offer, and well if you do, honor your word! My previous employer is now hiring me as a line captain when I left as a TRI. please try my shoes.
