What is going on with aviation security.

American Airlines briefly grounded flights nationwide due to a technical problem just as the Christmas travel season kicked into overdrive and winter weather threatened more potential problems for those planning to fly or drive.

Hackers gained personal information about thousands of people who applied to become pilots at American and Southwest airlines.

American Airlines is promising significant pay raises to pilots to match a recent deal at rival Delta Air Lines.

Pilots at another big airline are rejecting a contract offer to seek bigger pay raises.
