Flying may get just a little less frustrating and a bit more transparent starting Tuesday, when new federal airline passenger protection rules go into effect.

"It's huge," said Kate Hanni, founder of FlyersRights.org, who has fought for the changes for years.

"If you're flying on (Tuesday), you're 400% better off than you were before."

The Association of Passenger Rights also applauded the rules, calling them long overdue.

"If you talk to most air travelers ... traveling on the airlines is about as popular as the U.S. Congress right now," said Brandon Macsata, a spokesman for the group.
