Our March trip will be our 2.5 year old daughter's first time flying. We purchased her own seat for the flight. My question--should we bring her carseat for the flight or will she be ok buckled in her own seat? We are renting a car through National and for an additional small fee we can rent a car seat. Our flight is short--only a little over 1.5 hours. If people think she will be comfortable and safe buckled in the seat--we sure would rather not drag the carseat(already bringing stroller, bags, and another child). Thank you for the info on what has worked for you.
