Proposed airline rule changes at a glance

The Department of Transportation on Wednesday proposed new rules for airlines on overbooking and other passenger concerns. Officials said they hope to enact them by fall. Here are some of the proposed changes.

Overbooking: If an airline denies a paying passenger a seat because of overbooking, the airline would be required to pay up to $650 if a passenger is put on another domestic flight that arrives at the final destination one to two hours after the original flight. Compensation would go up to $1,300 if a passengers is put on a domestic flight that arrives more than two hours later.

Frequent fliers: Bumped travelers using reward programs, such as frequent flier miles, would be compensated at the lowest rates for a comparable ticket on the same flight.

Baggage fees: Airlines would be required to provide notice when baggage fees are increased and offer refunds when bags are not delivered on time.

Fair-price advertising: Airlines would be required to advertise the total ticket price, including taxes and fees, and disclose clearly when a one-way fare prices can only be purchased as part of a round trip. Airlines would not be allowed to increase the price of a ticket after the passenger has made the purchase.

Flight-status changes: The airlines would have to promptly notify passengers in the boarding area of changes to their schedule because of cancelations or delays.

Peanut allergies: The Transportation Department said it was considering three options to accommodate passengers with peanut allergies, including banning peanuts on flights with passengers requesting a “peanut-free” flight ahead of time or setting aside a “peanut-free buffer zone” near a passenger with peanut allergies.
