As one who makes is living from, and therefore spends a lot of time with
RJ's, I see no inherent problem with the aircraft. The problem is with the utilization. When employed in the manner they were designed for, they are quite efficient, useful tools. The problem comes when you use them for things they weren't intended for. Example, the 50 seat CRJ was not meant to do 3 1/2 hour legs in the configuration used by most US operations. Just because it can does not mean it should. They are also not cheap. Do not confuse low cost with poor quality. While every aircraft has its strength and weaknesses, I don't think any of the current selection of
RJ's is low quality. If there is "cheapness" then I would argue it comes from factors surrounding the aircraft and not the aircraft itself. As for schedules, you can either restrict the number of operations or add capacity. If you do neither, then you deserve what ever mess you get. My personal opinion, if you have a growing population and a growing economy, you should add capacity. Restricting the number of operations at an airport is an excellent way to artificially inflate fares.
For the record, I would not classify the E170 as a regional jet. Compare the statistics to the A318 or the B717. Each has a MTOW of over 100,000 lbs and a range of equal to or greater than 2000 nm. Being built by Embraer does not automatically make it an
RJ. The other side of the coin is, what defines a region. If North America is a region, then the 757 is a regional jet.
