Clarification:
No, the car seat we had was not a booster seat. It was a car seat. In no way would I mistake a booster seat for a car seat. It was a car seat, just like the baby had at home. I agree, a baby could not use a booster seat. When we booked Tiffany, we requested a car seat for the baby, and there was no problem. It was in the Van when we were picked up at the airport.
A BIG problem, though, was that US Air broke the stroller, and the Van driver waited patiently while my daughter was filling out the claims forms and getting reimbursed! Great Company, Tiffany!
