I pick airlines that have (almost) no Boeings and that I can call before booking to see if it's an Airbus. I have done that for many years before the 737 Max issues. I simply find them annoying (very noisy) to fly with, but I definitely try to avoid. Some times I find myself in a Boeing on short flights when suddenly another airline provides the plane and it may be bad luck or damaged hearing or whatever; every flight I get into (and I fly a lot) with a Boeing, the noise is horrible.
