Lots of friends at AA and UA…AA friends are not getting on WB any earlier than DL, and UA friends are sitting airport reserve for the foreseeable several years. Friends at DL are on 330/350 with 4-5 years at DL (I’ll exclude the crazy NH to 350B part). It’s all subjective, but I don’t really see those other two options as any better than DL, in fact I see them as worse options (unless one is interested in living in base at AA/UA). And if anyone makes the argument of, “well but that’s not a guarantee of how it’ll be in X years,” then you have to apply that same logic to the other airlines as well, which effectively cancels out that point in this discussion.
