Where can we find a following interpretation upon a United States made at home air transport market?

I am perplexing to assimilate some-more upon a combination of a US air transport marketplace as well as wish to know a following things:
How most people buy their sheet a day of travel? Within 3 days? 1 week?
How most tickets have been fully-refundable vs limited fares?
What does a placement of series of flights per year a chairman takes upon a US made at home newcomer marketplace (e.g., 10% of newcomer trade is driven by .1% of people, 20% by .3% etc)
