Thanks a lot for your reply. I assume it would be a bad idea to email the HR specialist and inquire about an A330 or 777 class instead, even if I had to come sooner? It is my impression that the class assignments are not negotiable, without regard to personal preferences and solely driven by the company's needs at the time of hire. I don't want to jeopardize my job opportunity by making a mistake at this late date, so any further insight you may provide would be most welcome. Best Regards, Sophia1997
