In the past the AAdvantage program has offered some of the more
generous award charts in the US Airline industry, the top - tier benefits were easily the best out of any US airline (I would argue they were the best in the world),
awards weren't especially hard to come by, upgrades were plentiful and, compared to its peers, AAdvantage was a
pretty great program in which to earn miles and status... especially if you traveled a lot.
