Airliners can continue to fly much longer than the current 737-700 fleets age. Two jobs ago, I flew 40+ year old DC8 around the world and to some very remote locations.
So what will be the replacement? The only one I see on the horizon is the 737-7 MAX, but who knows when that would be available with all of SWAs orders already on the books and the airplane still working through certification?
I don't know performance wise but could the a220-300 work to replace them? I know it's unlikely that United will add another fleet but it's the only other option, other than what you named, that I could think of.
