RE Not able to enter Canadian postal code.
Assuming it was to verify my credit card billing info as most online sites do, I ended up phoning and went through a lot of waiting, transferring until an agent entered it correctly for me.
When I asked if others had run into this problem before, I was assured NO never.
Judging by the comments here, that is not true.
yes to the question I did enter the country first.
I know the digital only trick as we too travel in the US but again, I assumed that it had to be correct format to verify the credit card.
Guess not!
Now I'm trying to find out when I can access the digital boarding pass...apparently not yet for our cruise in 5 wks time.
