Re: the former World's Favourite Airline
I believe at one stage it was absolutely true: BA _was_ the world's favorite airline. The "trick" was in that "favorite" is not the same as "best". So world-wide surveys asking respondents to rank their favorite airlines, BA frequently came in as a runner-up largely for a number of reasons, including that a lot of people speak English as a second language, so might rank their national carrier first, then English-speaking carriers, etc. So long-haul Brits might rank Virgin then BA, short-haul Brits might rank BA first, Scandinavians might rank SAS then BA, Hong Kong residents Cathay then BA, etc.
All-in-all, it's like many proportional representation schemes: a candidate that's no-one's first choice may still rank highest...
