Yes, in 2026, almost all major commercial airlines—including global carriers like Delta, United, and Lufthansa—allow you to check one car seat and one stroller per child free of charge. These items do not count toward your standard baggage allowance. For maximum convenience, you can choose to "gate check" them, meaning you use the stroller through the airport and hand it over at the aircraft door just before boarding. The crew will then have it waiting for you at the jet bridge upon arrival. Alternatively, you can check them at the ticket counter when you first arrive at the airport. Many 2026 travelers use protective travel bags to prevent damage during transit. It is important to note that if you wish to use a car seat on the plane, it must be FAA-approved (or the local equivalent) and you must have purchased a dedicated seat for the infant, as "lap infants" cannot use seats in the cabin.
