If the product or offering of one airline doesn't fit your demands and needs fly another airline.
Which is exactly what I do! Nevertheless I disagree that 28" is safe. Have you any idea how many people develop blood clots from flying in cramped conditions? It generally won't be felt on the flight itself, unless it's a long sector. Even then most people are not aware that they have developed the problem until a day or two later. This problem will never be identified as an in-flight medical issue and is therefore arguably conveniently ignored by both the airlines and the aviation authorities. Something being "legal"
mockingjay does not necessarily qualify it as good.
