Standard strollers, folding wagons, and car seats can be used to get to your gate and then checked for free. They'll be returned to you on arrival. Collapsible strollers can be stored in-cabin. Car seats can be used onboard your flight too.

3.Why use a wagon instead of a stroller?

Comfort of the Kiddos

One of the top arguments in favor of stroller wagons is that kids can self-board it. It's true for some because they might have a zip-door or folding entryway, I'm yet to see any toddler having issues self-boarding a regular stroller as well.

What Ages Are Wagons Good For? Wagons offer little ones less support than traditional strollers (even ones with five-point harnesses and seat belts for added security), so they're often recommended for toddlers older than 18 months who can sit upright unassisted, even over minor bumps in the road.
