they did not screw up your name..............its fine..............
screwing up your name is when they forget to type parts of your name or had a typo issue.............
i checked all my Aeroplan tix and they are presented this way.................
technically the airline ticketing is done by LASTNAME/FIRSTNAMEMIDDLENAME
For example John Jane Doe would be presented as DOE/JOHNJANE or DOE/JOHNJ or DOE/JOHN
