WASHINGTON — You can print your own airline boarding passes, so why not print your own luggage tags?

That’s just one of the baggage handling changes some airlines are trying out in an effort to save you time — and the frustration of not knowing where your bag is.

More than one-third of the world’s airlines now ask passengers to tag their own luggage. Frequent fliers on Alaska Airlines can get paid — in the form of 1,000 bonus miles — to tag their bag themselves.

The Wall Street Journal reports Air France-KLM will soon begin offering an electronic luggage tag, called an eTag, with a display screen you can change via your smartphone.

The airline is also offering a tracking device called eTrack, which goes inside your luggage and includes a light sensor, so it can tell whether your bag has been opened.

Both products are made by the FastTrack Company, and you can read more about them and watch an intro video here.
