Go to the airport kiosk to get a claim check for each checked bag. A claim check is like a receipt. Keep each one until you reclaim all your bags at your last stop.

It's unlikely your bags will be lost during travel. But there are 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.
