One thing that has changed since I went through new hire is per diem is no longer given if you are sent somewhere else for sim than PHX. Toronto and Copenhagen are very expensive. If you put it all on a credit card trying to pay for food, beers, etc. you'll be spending your first few pay checks online paying for your experience abroad. As someone pointed out they try to not send you away from PHX when you are a new hire, but sim time is tight and they will if thats where the time is. I also heard Berlin as a rumor a few days ago.
