Plane Diverted

A Southwest Airlines plane sits on the ground in a remote section at Phoenix Sky Harbor International Airport after the FBI says a "telephonic bomb threat" against a Southwest flight from Los Angeles to Texas led to the plane being diverted to Phoenix on Monday, June 10, 2013. Flight 2675 left Los Angeles International Airport at 2:12 p.m. and was heading to Austin before the threat was received by telephone. The plane landed safely at the Phoenix airport at about 3 p.m. (AP Photo/Ross D. Franklin)

Airline Fees

U.S. airlines collected more than $6 billion in baggage and reservation change fees from passengers in 2012, the highest amount since the fees became common five years ago. These fees along with charges for boarding early or picking prime seats have helped return the industry to profitability. (AP Photo/David Goldman, File)

Knives on Planes

FILE - In this Sept. 26, 2006, file photo, knives of all sizes and types are piled in a box at the State of Georgia Surplus Property Division store in Tucker, Ga., and are just a few of the hundreds of items discarded at the security checkpoints of Hartsfield-Jackson Atlanta International Airport that will be for sale at the store. Federal officials say they’re delaying a policy that would allow passengers to carry small knives, bats, and other sports equipment onto airliners. The Transportation Security Administration said Monday, April 22, 2013, that the policy change has been delayed to accommodate feedback from an advisory committee made up of aviation industry, consumer, and law enforcement officials.(AP Photo/Gene Blythe, File)
