An Alaska Airlines passenger has watched his lost AirTag fly between 37 cities for months after it fell out of his bag

• Éric Béteille said his AirTag has been stuck in the cargo space of an Alaska Airlines plane.
• For the last nine months, he's tracked the Embraer E175 across 37 different cities.

AirTags have proved to be helpful devices for recovering lost baggage, but what happens if the tracker falls out?

In a Facebook post, Éric Béteille said his AirTag fell out of his luggage tag on an Alaska Airlines flight last July — and is now stuck in the plane's cargo space.

"I've been tracking it around the western US and Canada ever since," he said.

He used data from Flightradar24 to make a map of the 37 cities that his AirTag has flown to over the past nine months. It goes as far south-east as Austin, and as far north-west as Vancouver.

Other locations included Missoula, Montana; Jackson Hole, Wyoming; and Tucson, Arizona.

Béteille — whose LinkedIn profile says he is a principal content designer at Meta — has racked up over 20,000 likes across his two Facebook posts about the lost AirTag.

He said the plane, an Embraer E175LR, has averaged at least five flights a day.

It's a smaller type of jet, which seats 76 passengers and has a maximum range of 2,500 miles.

Béteille's AirTag won't be going transatlantic, especially given that Alaska Airlines only flies to North America, but it's still an interesting insight into the carrier's operations — and the frequency of one jet's flights.

In a similar incident last year, travel news site View From The Wing reported an American Airlines passenger watched his AirTag fly to 35 different cities — after he put it in his wallet and accidentally left it in the cabin.
