Is there a standard system-wide boarding priority for Stretch Seating? I flew SFO-DEN-GRB and return over the weekend. I was late arriving to the gate SFO-DEN so I missed any priority boarding. The DEN-GRB did not have preboarding for any passengers other than priority and those needing more time, as far as I could tell.
On the return, rows 1 and 2 were included in the preboarding at GRB (Republic E190 with 1 x 2 seating in Stretch / Signature) and all Stretch Seating was preboarded for DEN-SFO.
If priority boarding will be a standard benefit of Stretch Seating, it should be noted in the amenities. I definitely would be more likely to upgrade if this is a benefit.
I flew MKE-BOS (Frontier Airbus) last Friday and there was priority boarding for Stretch Seating passengers.
