It's unlikely your bags will be lost during travel. But there are a few steps you can take to help reduce this risk:
- Before going to the airport, remove all old bag tags.
- If you're checking a bag, make sure you get to the airport early.
- Keep your bag tag receipt. You should also take a picture of your bag and bag tag receipt together for your records.
- Place your phone number or email on a luggage tag or inside the front pocket of your bag so if your bag tag is lost, we can contact you to confirm where to send it.
- Use our bag tracker or a device like an AirTag to keep an eye on your bag.
- Place medication, valuables and other essentials, like keys and your wallet, in the bag you plan to bring on the plane with you.
- Pack all liquids in a resealable bag. Liquids more than 3.4 oz (100 ml) should be packed in your checked bag.
