I will be traveling with my daughter, 2 1/2 yr old grandson, and 3 month old granddaughter in August. I know she is planning to gate check a stroller and car seat. She just told me that she is planning to take the tandem stroller since we will be changing planes in Chicago. I have flown a lot but never actually noticed the types of strollers that were gate checked. I'm wondering if a tandem stroller is okay to gate check. Does anyone have any experience with this? We have just about 90 minutes between flights. We are flying United if anyone has any experience with them. My concern is the tandem stroller might be too big to maneuver in the jetways and obviously we will need to use elevators. Any thoughts from some experienced parents or grandparents traveling with kids these days. My memories are from 30 years ago with kids and it was a totally different experience then. Thanks.
