Skywest's CR2's are, put simply, crap. I've flown them a couple times SLC
cut mainline. The seats are more narrow, with less pitch and otherwise not very comfortable. The windows are small and low-set so it is difficult to see out. Carry-on baggage space is limited. I'm not sure, but I think the same aircraft operated for UA
get a slightly better seat pitch (Recently flew Skywest/UA Express MSO
and it wasn't too bad, but the service for DL
made me want to vomit). Service is pretty much standard, and skywest has a very tasty snack mix that is one of my favorites! All in all mainline is definitely a better product. Since snack mix is not a reason to fly, I'd avoid the CRJ.
