Interesting opportunity for travel insurance: a policy that refunds your ticket if the plane turns out to be a 737 (even at the last minute).

I realize it's not a viable business idea, but I'd feel such Schadenfreude if Boeing had to deal with the optics of that.

JetBlue doesn't fly any Boeing planes so as long as it isn't a codeshare flight you should be great.

Better yet, fly Breeze Airways

which is building an all new fleet out of modern A220 and E2-Jets. Breeze is cheap enough that I am thinking about riding to some random city and discovering a reason to go there because I want to ride in an A220.
