My friend is on AA135 tomorrow sitting in the new PE seats but is still MCE. I'm eager to get his report because I'm booked on that flight a couple of times this summer. The PE service start date for AA135 is 6/27. Before 6/27 it's PE seats but no extra service and then beginning on 6/27 AA135 PE service goes into effect. I'll ask him about the armrests.
