That's absolutely not logical. With a lot of frequent flier miles you are very likely a status customer and airlines will bump those last and, depending on the status, will bump other low revenue passengers to make space for a high status customer. I know a bit about aviation and if an airline really needs to involuntarily bump a passenger (which is quite rare) they will chose an infrequent flier with a cheap ticket. Unless you can provide a source for your assessment I call bullshit.
