Call the airline and find out if the Graco car seat, base and stroller are counted as baggage. Some airlines, like Delta Airlines, will not count these items as baggage. Many airlines restrict the number of bags each person is allowed to carry; find out if you will be charged extra for any of these items.
Arrive at the airport with the Graco travel system. Place your baby in the stroller and wait in the check-in line. If your arms are too full to carry the car seat separately, strap your infant in the Graco car seat, and snap the car seat into the stroller.
Check the car seat in with the rest of your luggage. If your child has her own ticket and reserved seat, you can keep the car seat with you and keep her strapped in the car seat on the plane. Some airlines require children who will fit in a rear-facing car seat to use one if placed in their own seat on board. If she doesn't have her own ticket, check the seat in. If needed, pay the fee to check in the extra baggage.
Roll your child in the stroller until you are allowed to board the plane. Before you enter the plane, take your infant out of the Graco stroller and collapse it. A flight attendant will load it on the plane for you. When the flight is over, the stroller will be waiting for you outside the door.
