If you get bumped: Passengers can collect $1,300, up from $800, for being bumped from a domestic flight if they arrive at their destination more than two hours later than scheduled. Consumers can collect at most $650, up from $400, if they get to their destination within two hours.
If your bag is lost: Passengers who pay $15 or more to check luggage will get a refund if their bag is lost.
If you're looking for the lowest fare: Airlines will have to include taxes and government-imposed fees in the fares that they advertise.
If you're stuck on the tarmac for an international flight: If you are not allowed to leave after four hours, the airline could face fines of up to $27,500 per passenger -- more than $10 million for a superjumbo jet like an A380.
When the rules begin: In late August.
