New regulations going into effect today are expected to help ensure that consumers are treated fairly when they travel by air.

Among the new provisions are requirements that airlines and ticket agents include all mandatory taxes and fees in published airfares and that they disclose baggage fees to consumers buying tickets.

Also beginning today, passengers will be able to hold a reservation without payment, or cancel a booking without penalty, for 24 hours after the reservation is made, if they make the reservation one week or more prior to a flight's departure date.

Airlines will also be required to promptly notify passengers of flight delays of over 30 minutes, as well as flight cancellations and diversions.
