Remember the campaign last fall called "Mad As Hell About Hidden Fees?" Some of what that effort sought was included today in the release by federal regulators of new rules that reqjuire airlines to tell customers what it's really going to cost to make a trip, in addition to the air fare, before they buy a ticket. Full disclosure of all fees in all of the channels used to sell airline tickets is still under consideration but wasn't included in today's release of the proposed rules.
DOT also will make international airlines follow the same general rule on long ground delays. Read more about all of it in two articles, one by the AP that emphasizes the tarmac-delay rule, and another in the New York Times that covers the other rules in more depth.
