By the time another generation has come in, they will be amazed to learn of 'full service'. It will be ancient history, just like a boat taking six week to reach Australia and the crew falling sick due to poor food preservation. No, it's not nice to see things change from how they have been - but that's how humans have come to dominate the planet.
Don't fret too much about BA, it's into the 'home straight' now ... (and to repeat, I say that with no joy, as it will be horrible for a lot of people when it crosses the line.)
