Are airline bag fees worsening security lines?

As airport and government officials search for a fix for the long airport security lines plaguing airports in Atlanta and other U.S. cities, one possible culprit has come into focus: Baggage fees.

Some say fees for checked bags prompt travelers to carry on more bags, all of which have to be screened at security checkpoints as passengers head to their gates.

Two U.S. senators have proposed that airlines stop charging baggage fees this summer. But airlines are loathe to lose the hundreds of millions in revenue they collect from baggage fees.

Now, Hartsfield-Jackson is considering — but has not committed to — another possibility: a “one-bag only” express lane, with the idea that those travelers “have the potential to get through the process quicker,” airport general manager Miguel Southwell said.
