Only had the ipad treatment once. Felt slightly embarrassed by the whole affair since the passenger next to me was staring at the whole affair. (Though secretly, of course, I was feeling smug that I got the message and nobody else did.) I was also wondering at how this thing works since I knew of at least two GGL on the same flight that didn't get the message.

Don't really care about the ipad treatment. The thing I would really prefer is that they stop using the generic "Sir" and actually work out from their passenger list what my name is.
