Majors' scope precludes almost any future growth in the 70/90 market, even as 1 for 1 replacements for 50's. Therefore, the Regionals will continue to fly 50 seaters as a staple of feed into the future. American is the only one I can think of recently that is allowing more 70 seaters. Not sure what United's cap is, but I believe Delta is at the limit and I don't think Continental allows any 70 seaters. So, are we saying that if 200's need to, or are going to, disappear, then who or what will feed the hubs?
