1) A friend or family member drives you to the airport and picks you up.
PRO: Easy for you. Build lots of time into the arrival time. For international flights, you need to arrive two hours in advance. You need to take traffic and time to get through security into account. You could plan way in advance and pay to join the TSA quick security program. Be sure to print your boarding passes beforehand.
CON: With all your luggage, perhaps a car seat and stroller, your driver may need a large car. If you have flights at odd hours, it may be inconvenient and a lot to ask. Be sure to have your driver check with the airline website on the return to be sure your flight will be on time. They can sit in the airport cell phone lot and you call when you land. Be sure to allow time to go through baggage claim, immigration and customs on the return.
