The PC they provide is set up so that it wipes itself every time somebody logs in, which in theory protects you from somebody eavesdropping and/or stealing your information. The down side to this approach is that you’re stuck with whatever they decide is the right version of software to work with.
You’d think this wouldn’t really be much of a problem, since I’m sure they probably have some sophisticated check that will catch if the browser doesn’t have Flash and redirect you.
… Except …
The PC did have Flash loaded, but the JetBlue page wanted a higher version installed than was on the machine. So the browser helpfully asked if I wanted to upgrade, which I said “yes” to, only to find that the generic login doesn’t have install permissions (surprise, surprise).
So I asked the desk to help, but they had even more locked down machines, so I figured I’d just have to punt.
Back down to the hotel computer, log into my Google Docs, open the PDF and presto – the boarding pass is printed !
