Hard disagree. First, when I was flying regularly, it was during the height of the original 737 Max scare, which also occurred within a few years of the CFM56 fan blade problems and the 737NG pickle fork fatigue cracking problem. It was a rough couple of years for the 737 family, yet I didn’t notice any serious uptick in equipment changes, and I was flying on airlines with a bunch of 737s in their fleets. Second, the idea of some conspiracy involving falsely advertising which airframe an airline intends to use for a flight, which would involve submitting false flight plans and publishing false flight data, is patently absurd to anyone who has been exposed even as an end-user to the tech stack of the airlines, such as it is. Between getting licensed employees to lie to the government and the airlines antiquated software, I don’t believe they could do what is being suggested, even if they wanted to.
