Etihad, Qatar, Emirates are rated among the best airlines. I don't know where you are flying to and from, but if you are tall. I would go for ANA (33"-34") or some other Asian airlines instead. The seat pitch is 32-34" with some at 31" but european airlines are 30"-31" and qatar and etihad flights are 31" seat pitch in economy meaning not so much leg room.
i did... But it's pretty vague and it doesn't say anything regarding whether or not it has to be business account or personal and as far as the portfolio for remote work... It doesn't say much more than that.
It's a lot of money. Want to make sure everything is done correctly and not get rejected.
