New air passenger protection rules set to take effect

Airlines will not be able to leave international flights on the tarmac for longer than four hours and have to pay passengers more if they bump them from oversold flights under new Department of Transportation rules set to take effect this week.

Under the new rules, the DOT will fine airlines $27,500 per passenger if they leave international flights stuck on airport runways for longer than four hours and require airlines to pay passengers double the value of their tickets up to $650 for short delays from being bumped and $1,300 from long delays.

Airlines will also have to refund bag fees if passengers' luggage is permanently lost.

The rules are set to take effect Tuesday. The DOT plans to implement additional passenger protections early next year.
