What are the Requirements for Traveling with Smart Luggage?

If you are carrying smart luggage as carry on, you will need to ensure that it meets the standard carry on measurement requirements. Please note that the lithium battery may not exceed 100 watt hours. Also, be sure that all transmitting capabilities are turned off during flight. If you plan to check in your smart luggage, you must remove the lithium battery and carry it with you in the cabin storage of the aircraft. 

Is There an Advantage to Paying for my Bags in Advance?

You will definitely want to pay for your bags in advance! You can prepay for both carry-on and checked luggage when you purchase your airline tickets. Other benefits to pre-paid services include adding bags, reserving seats, and upgrading to priority access. You will only be able to arrange for these savings and services if you do so before you check in or print your boarding pass. 

Is there a charge to bring a stroller or wheelchair?

All medical and assisted devices, including wheelchairs, canes, walkers, and strollers are free of charge. They will be checked in and delivered to the gate upon arrival.
