There will be some traction for any airline (e.g. location, schedule convenience, brand image, excellent business class seat) and you will note that I was writing about future posibilities, not the present situation.
Some people on here report very poor experiences with BA and others report very good experiences and it is well understood that people are more likely to complain than praise, so my take is that the majority of passengers are probably happy with their BA flights.
However, your comment about the choice for those with money being charter or BA premium cabin is simply bizarre. BA faces stiff competition from many full service carriers and on the far eastern routes it is pretty intense.
If BA does let standards drop in the future, the competition will murder them.
