The problem with boycotting Airbus, that I've found, is that most airlines that I've flown on either won't tell you what you are flying in until you sit in it and take out the safety instructions, or they switch planes without telling you. I know this because I've tried to avoid flying on Airbus's even before this latest outrage by our "allies". Not only did I not want to give money to this French govenment subsidized industry for the transgressions of the French, but I don't feel I am as safe on one as on a U.S. built aircraft.
The best you can do is to try to fly airlines that don't own any Airbus's and tell the one's that do why you are not flying them.
Yes, I have heard of Airbus. I have also heard of French wines and perfume, German beer, and Porsches, BMWs, and Volkswagens. None of the above have been, or are likely to ever be, useful to me in maintaining or improving my quality of life.
