As I mention, which country has any appetite to join this conflict? I suggest none.
We are not flying around Russia, we are flying into Russia and flying around Ukraine... big difference and this is nothing quite as severe as the blockade was.
With regard to the start dates changing, this is nothing new here; it is simply a reflection of our poor management and planning. So yes, it is good to know what you are getting into. Qatar Airways is a shower of ****, where the left hand doesn't know what the right hand is doing. The new joiners aren't even enough to replace the monthly exodus of pilots escaping.... forget any expansion, this is damage limitation at the moment.
Best of luck
