how many people fly BA annually?
Any idea where to find a good source for the number of people who fly BA (or other airlines) per year?
It's easy to find stats on the number of passenger flights per year (69 million for IAG in 2012 per their web site), but I believe that counts a person who takes 10 flights 10 times, and I'm looking for the number of discrete people who take 1 OR MORE flights on the airline within the year.
thanks for any pointers,
Bob
