We're taking our son for his 1st flight today and we connect in IAH but we have to gate check the stroller and car seat. It's a 757-200 and we're in 1st class, but I have no idea how long we have to wait. Our connection is only 51 minutes so we're going to have to be on time as it is, but if it is a long wait for the gate-checked items, we're in trouble. I can't say I ever noticed anyone else's gate checked strollers on the bigger planes before- does it take long?
