Need help deciding on which carseat to order specifically for traveling. We will use this carseat for at least 3 flights in upcoming months, ranging from 5-13 hr flights.

Comfort is important and some reviews of the Scenera make it sound rather uncomfortable for LO to sit in long periods or time or fall asleep in. Some reviews of the ComfortSport have issues with the straps.

Trying to see if any Bees here have good/bad experiences with either?
