All of these GOOFY Routes that are being serviced by 737 & CRJ 900 is a Ripple Effect Due to the Hawaii Service.
U*S (West) has pulled most of the 757's from the 48 states and replaced them with 320 / 319.
This then caused the cities that were being serviced by the 320 / 319 's to be replaced with 737 & CRJ 900.
This is just like all of the Trans Con Routes from 2004. ( Who knows how long they will keep "FLEXIN" the Hawaii Service. ( Multi City / Multi Day)
You never know they might cut back all of the Island Service from Mainland and ADD the Value of Mesa to server as Inner Island on CRJ 200
