20% of the flying on the DFW 787 is domestic, think about that. As more 787 come online, I think you will see more and more of them doing high load, and seasonal, domestic flying. It is so efficient that using it on some routes over the 321 might be advantageous considering CASM vs RASM.
Why the company is pulling down high load routes, like PHX-DFW is mind boggling. They went from almost all 321’s (with a segment or 2 using CRJ’s in peak time..ex.510am departure (321), 540am (CRJ)) with a minimum of 187 seats, to 321’s mixed in with 150 seat planes like the 737 and 320, but also have the 757 from time to time. The loads are outrageous on those flights at almost all times of the day, everyday. They could easily fill a 321nx on that route almost everyday, and I bet one 787-8 mixed in would probably almost fill up too.
Maybe it’s full cause of training, but damn, I just did it today on a 320 and the list was unreal, even with revenue oversold. No weather/delays in sight at either location. Just too small of equipment on that route. I am sure they are doing it in other places, I just see it more often on that leg.
