And the RJ's burn way more fuel (and I mean WAY MORE) than the comparable turboprops yet the majors haven't given serious thought to go back to them. CAL is the only one, with the majority of the majors issuing RFP's for large RJ's.

If fuel burn was their primary concern we'd see a lot more RFP's for TP's on the table IMO like the Colgan Q400 one instead of the numerous -900 RFP's.

The 170's really spanked the CRJ. While my company operates only CRJ's, thankfully they don't have the size of fleet like the "major" regionals do. Personally I see the 170's doing most of the domestic RJ flying in the future.
