Ok - I checked in on my PDA today... worked great (except for the previously reported 1 minute bug).

I elected to receive the boarding passes via email. I was able to see them in Acrobat moments later on my WM6 PDA.

I did notice that on my Blackberry, the only attachment was a large winmail.dat file.

Back home, I saw that this was true in Thunderbird as well. Seems you can only access the boarding passes using Outlook!

Given that I'd email the boarding passes when printing is difficult, I'd guess that people often use gmail, yahoo or other accounts to access and print. Shouldn't be outlook only (assuming that I didn't stumble upon something else).
