[QUOTE=block30;1830956]They routinely put 145s and 200s on hub-to-hub routes. Does that make those airplanes a mainline aircraft?

I agree about the 1000nm part though. A 3-hour flight is a mainline flight. Anything over 1.5-2 really.

[QUOTE=Mercyful Fate;1830954] Whatever mainline scope says it is....

TSA and Skywest ordered the MRJ 90 series.....that's the 86 to 96 seat version

[QUOTE=CBreezy;1830960]Sure. Let's put them back to mainline.

[QUOTE=Mercyful Fate;1830959]before coming to TSA...shuttle america almost did exclusive hub to hub

ORD to EWR
EWR to IAH
IAD to IAH
IAD to DFW
DEN to IAH

and tons more

Had a SkyWest corporate officer in my jumpseat, not saying who but he's a big shot. SkyWest will never see the MRJ. Many moons ago when it was choosing between buying the CRJ-200 and the ERJ-145 they had both companies bring one to St George, this while knowing full well that they were going with CRJ's all along. That is THE BEST way to get somebody that's selling something to come down on the price. Fast forward to now, same trick, I even know how much it's going to cost to back out of the deal. To you and me its a lot but the cost saving will be realized with just two aircraft orders. Also long term plan here is to go with an all ERJ fleet, but that's WAAAAAYY down the road. And our airframe count is coming down too, there's been articles in industry publications so this isn't new news. Right now SkyWest Inc. has about 740 airframes and it will come down to 600 total across both companies. Canadair apparently sucks for supporting the 200's and the 900's are being delivered with a known AD that costs over a million to fix when the time comes up. But as we all know things are not set in stone when it comes to planning. Good example is, the EMB-120, same guy was tasked with winding down those three different times, he was always able to find a nice balance of spare aircraft vs. block hours and turn a tidy profit since they mostly went into high yield markets. Then Part 117, and the one remaining parts supplier charging a fortune for parts, and its over in a couple months. But then MRJ's could all of a sudden be selling for half off and then the metrics change drastically.... that's life!!!!

[QUOTE=Mercyful Fate;1830954]Everything flown under the the mainline code like UA, or DL is a mainline route. Some are outsourced, and some are not.

[QUOTE=24/48;1831016]we all know that he was asking what should constitute a regional vs mainline route.
