I dunno about the seniority issue, but I asked the 11 I have flown with over the last three days. 3 hard yes, 7 going to vote yes even though they don't like it, 1 hard no.

Of course, I wouldn't bet the house on this as the outcome and it isn't a double blind study and most likely not a representative spread, but since they released the details, it has been overwhelming yes (with a meh attitude) from the peeps I have flown with. However, the prevailing thought is to get something on paper.
