Understaffed airports have increased the incidents of lost bags, but if you can’t travel with just carry-ons, at least you can know where your bags are located! Apple Air Tags are both affordable and reliable. These devices are very compact and can fit and hide almost anywhere. They are always “on” once you activate them and the battery lasts a very long time with standard replacement batteries readily available. The tags work by “pinging” any Apple device they see via Bluetooth. This includes airline workers and other travelers. It will register your bag’s location anonymously. There can be some issues with accuracy until someone with a modern iPhone goes and looks for your bag. But there is no subscription required like some of the more expensive trackers that use both GPS, Bluetooth, and cellphone towers. They also come with some other useful features like alerting you when you leave something behind – which is not what you want with luggage, but might work with your carry-on!
