Unlike other service providers, a common carrier by definition cannot refuse service to anyone willing to pay the fare in the tariff. Common carrier laws are some of the oldest consumer protection laws, enacted to protect travelers and shippers of goods against predatory and discriminatory pricing. Federal law recognizes the "public right of transit" by air, and requires boith airlines and Federal agencies to respect it.
This is only true for the "ticket purchase" not for the service itself.
Outside of ERs in exigent circumstances, any commercial enterprise in the U.S. retains the right to "refuse service" though the nuances of enumerated reasons backed by jurisprudence differ by industry and locale.
An airline can not refuse the "service purchase" unless the customer has been "banned" (technically a trespass statute), but they can refuse to "execute service" for a whole host of reasons including unforeseeable "Acts of God", logistics, or simply if the customer is intoxicated.
This is not true, in at least 2 respects: (1) a common carrier has a legal duty not just to sell a ticket but to provide transportation according to the tariff, and (2) this means an airline can't order a passenger not to board, or order them off the plane, unless they have violated some terms of the tariff. Some airlines have tried to create their own no-fly lists, but without opening up another area of discussion these have no more basis in law than the government's no-fly list, and have never (so far as I know) been reviewed by courts.
There are customers banned from airlines for various reasons.
