Posting here since it's not related to earning miles. I have to book SAN-ELP for a weekend trip in October. It looks like I will be using a regional jet for the first time, even if I go through hubs like DEN, DFW or IAH. My understanding is that there are several contractors and service providers for regional jets. My choices are as follows: American Eagle (through LAX or DFW on AA) ExpressJet (through DEN or IAH on UA/CO) Mesa (through PHX on US) SkyWest (through LAX or IAH on UA/CO) I understand that ExpressJet and Skywest have at least merged on paper, but I'm not sure if they are fully one company yet or not (e.g. in terms of branding). Assuming that I'm in coach, and that price doesn't matter much except for tradeoffs in time and the possibility of earning more miles (cheapest flights have been mostly stuck around $330 RT for weeks no matter when I look), what are your views of the regional carriers and/or the planes that they fly?
