Statements like “thing of the past under any scenario” don’t leave much wiggle room if you intend to follow through, but statements from airline management should be taken like those from politicians. They will say what people want to hear, and if it actually happens, then all the better. I don’t think that the single class 50 seaters will be completely gone any time soon, but I do think that they will take a major hit. Kirby doesn’t want to free up more 76 seaters with a new NB fleet type, and UAL pilots aren’t going to relax scope. My guess is that either the 145’s or 200’s are parked by 2025 and that there will be a shift back to reduced frequency on larger planes, especially with the new emphasis on our environmental impact and potentially raising fuel prices when demand increases. There may be a few single class 50 seaters serving very small markets, but more flying will shift back to United. Instead of 8 flights a day on a 76 seater, there will be 4-5 on a 320/737, those markets served with high frequency 50 seaters will get fewer 76 seaters..... Our competition is going the same way. Delta is completely eliminating their 50 seaters, and Southwest and the LCC’s don’t use rj’s at all.
