Here's some more numbers (all average):
Horizon Q400
Pounds/hr: 2130
Speed: 262
Horizon -700
Pounds/hr: 2190
Speed: 351
Almost the same average fuel burn for going 33% faster. Turboprops are great for short hops but there is a reason the airlines don't use them on transcons

Yes, to a point.

Almost the same average fuel burn for going 33% faster (therefore 33% less fuel burn). Turboprops are great for short hops but there is a reason the airlines don't use them on transcons.

.T-Props are for hops less than 1.5 hours. Jets when compared to the same shorts routes are extremely inefficient. Just run the numbers for the CR9 between ATL and GSP then compare it to a Q400 on a similar short hope. (compare the CR9 to the Q4 because there are basically configured for the same number of seats)
BTW, we usually burn about 3000-3600 lbs of fuel between ATL and GSP (25 minute FLT).
We all know that on longer routes Jet are more efficient but when it comes to 400 miles or less, props will almost always win out.

I don't know what the numbers are personally. That would require quite a bit of math and guessing, and also be operationally dependent. For example in the NE where you generally are kept lower and brought down from altitude further out and slowed the requirements would be different than out west where a jet can climb up to altitude quickly and then do an idle decent down at normal speed.

maybe some problems can be fixed like any other machine, but is it worth the risk??? SAS doesn't think so.

Btw, I noticed the flag in your avatar - have they switched to € in Slovenia?
