look at your list - what remains if you exclude anything with >40% of boeings? not much. and even after that, it is still a lottery.

You can’t see that 10 out of 19 on that list are <40% Boeing? If you fail that step, then boycotting Boeing is indeed hopeless for you. You should also be able to use your head and derive a cutoff that’s tuned for your local options. The 40% was a good threshold for that sample 7 years ago.

That list is a very small sample of airlines worldwide. And why are you trying to draw conclusions from figures that I said were 7 years old in 1st place? The guide is not going to do your homework for you. It shows you /how/ to derive the info and how to use it. It’s not written to give precise answers when some people live in regions where many of those airlines don’t even operate.

not even selecting specific flight based on an aircraft type is going to help you, because airlines swap aircrafts routinely, same as bus operator would swap buses. bus has a problem, just take another one.

No, it is not the same as swapping buses. Bus drivers are versatile. They can drive a Saab bus just as well as a Mitsubishi. You can’t just take an arbitrary Airbus pilot and put them in a Boeing. Very few pilots are trained in both. So if you’re going to swap brands, you have to send off two pilots and bring in two others. And if your Boeing fleet is small (as my advice suggests), then you also have fewer Boeing pilots to be able to spontaneously call to duty. If you lose on the odds that a/c are not swapped, and you also lose on the odds that brands are not swapped, passengers have demanded not to fly on Boeing then they discover they boarded one, and airlines /have/ been accommodating anyway.

What a silly attempt to claim a Boeing boycott is impossible.

if something changes in the industry in will be battle behind the scenes and it will happen by airlines gradually buying more from one manufacturer at the expense of the other, not as a result of enlightened traveller’s action.

The ol' “boycotts don’t work” claim.. that never gets old, but there is always fresh evidence proving the contrary. Such as McDonald’s HQ recently buying up all the McD’s in Israel after the private owner offered free meals to Israeli solders which triggered an international boycott against the McDonald’s brand. Brand protection was important enough for McD’s to buy over 300 stores just to change the policy.
