No question, that as a pure $/mile cost, it's cheaper to fly bigger planes than little planes. Add in many of labour contracts, and that cost advantage tips to a negative. Southwest, Frontier, jetBlue don't have the ridiculous labour contracts, and also don't fly to smaller markets and hence can fly 737s/A320s comfortably. Of course, Southwest is a point to point carrier, which leaves different metrics altogether.

I'm not sure that's a problem.
