Here's all you need to know about aircraft at RAH:
-Stay away from the CRJ unless you live in or near IAH and don't mind collecting your min guarantee while sitting reserve.
-The 170 flies itself. Sometimes the pilots have to wake up and put the gear down, but that's only when the Auto Gear Putter-Downer is MELed.
...of course, this is all from a 145 guy who's still having trouble getting his seat exactly where he wants it.
