Just something that came to mind.
I know there have been many, many threads on which airline is the largest. However, this can be defined in many ways (just like which airport is busiest, for example).
So, my question addresses several of these characterization methods.
Which airlines it the biggest in terms of:
1) Fleet size?
2) Destinations Served?
3) Passengers carried?
4) Miles Flown?
5) Countries Served?
6) Total Profit?
And, if there's any other "fun facts" people are aware of, or want to throw in as a further definition of an airline's "size" please feel free! I'm always here to learn more!
