I travel entirely for leisure, although I self fund myself moving around a few of my work sites and home. Those flights go to another airline's program, though.

For BAEC, I am entirely self-funded and the flights are for leisure. I get a kick out of travelling and decided a number of years ago that I was going to structure my work around my desire to travel internationally, and I was going to spend a chunk of my income on that too. I'm looking for value when travel, so have to think hard about what I fly. The decision to switch to BAEC was after QFF had devalued their program, and I've always liked BA when flying (except the heavy fuel surcharges!).
