American Airlines is the newest carrier adding free live baggage tracking. Travelers are now able to follow their bag’s journey online, from check-in to arrival carousel, via the AA tracking site.

To use, passengers input their name and record locator or bag tag number on the tracking site. The information relays the bag’s location in real-time.

American Airlines isn’t the first to offer an online bag-tracking service.

Delta and US Airways (now part of American Airlines) were among the first to let flyers follow the status of their bag. Air France-KLM has also developed a bag tracking solution with permanent, reusable electronic tags that are affixed inside and outside the bag.

Passengers can track their bags in real time via their smartphones, thanks to GPS, GSM and Bluetooth technology.

Before year’s end, the Tumi Global Locator tracking device is also set to hit the market. The smartphone-enabled app allows flyers to follow the status of their bag regardless of airline.
