American Airlines

A tense confrontation between an airline and a passenger was captured on video, Friday. This time, an American Airlines employee is accused of hitting a woman with a stroller.

All three of the biggest U.S. airlines now offer no-frills, discounted fares called "basic economy." Now there's evidence that it's not any cheaper, but is a way to raise standard economy fares.

An American Airlines 767 aborted its takeoff because of what airline says was "an engine-related issue." The plane caught fire and passengers were evacuated.

American Airlines is urging pilots and crews to fly faster and take shorter routes to decrease delays. The pilot union says this "pilot pushing," as they call it, will thin the margins of safety.

Mergers have left the airline industry with four huge carriers: American, United, Delta and Southwest. But competition may be around the corner — from foreign carriers or young entrepreneurs.

Flights have resumed after what the airline called connectivity issues caused ground stops in Dallas, Chicago and Miami.

The department says it is looking into "possible unlawful coordination" by several major carriers. American and United have confirmed that they are among the airlines under scrutiny.
