My company operates both the CRJ-900, and B737 series -300, -700, -700NG, -800NG.

All the Boeings have various engine settings of (I think) 22k, 24k, 26k. The CRJ-900 just has the one 14k setting fixed. On paper, the CRJ will outrun the Boeings quoted, but I think on a seat mile basis, they beat the CRJ on fuel burn.

Not sure why you're cruising at such a fast speed. I think the official Bombardier number is M.77 for LRC, which is about what is typical for Boeing. Not much difference. Both planes can go M.82, I think. Yes, the CRJ can go a bit faster, to M.85, but there are speed hits for RVSM that equal Boeing.

In climb, there may be a nod toward the 737 (not in a -300, for sure). Edit: Almost forgot to say, both the CRJ series and the B737-NG series are certified to FL410. No difference there. Much like the early CRJ's (100-200), the early B737's, can't do FL410 (ok, somebody will get all excited and let us know how the early CRJ's are "certified" to FL410... thanks in advance).

Hey, the 737 was designed in the early 1960's, and patched up for almost 5 decades. The CRJ is a relative new comer, so it should do many things better.

For all the haters out there, I'm not comparing a CRJ-100 / -200 to anything. That plane is a PIG !
