American’s argument boils down to DOT rules were never updated for the information age so they’re permitted to keep their rules off the website where customers would normally expect to find them. As American puts it, “[t]he tariff public inspection requirements were first adopted by the Civil
Aeronautics Board (“CAB”) in 1965, well before the development of the World Wide Web.”
In other words, American says they haven’t broken any rules because the rules themselves are broken.
