I know that West will also start one of the PHX-CLT runs starting this summer, as well as a PHL-SEA run.
Don't know if East will pick up anymore PHX flying early and late like MSP, DFW, LAX, ORD, SEA, etc., or any midday flying like PHX-SAN. Same goes for anymore LAS East flights like the recent PBI-LAS.
But I would really like to see some more connecting of the dots. Once the reservation migration was complete, I thought we would see some CLT-SAT, AUS, ELP(?), OKC, OMA, ABQ...etc. And I also thought there would be room for some PHL-SNA, SLC, AUS, SAT, SJC...etc.
The only things we have seen like this are PHL&CLT-PDX. Besides that, new flying like PBI-LAS utilizes 2 markets that were already served by East. No taking advantage of new city pairs that weren't availble pre-merger (without needing to open a new station) seems kind of ridiculous to me. There has got to be demand for some of those stations.
