Factor rental-car return time into your schedule

If you need to be at the airport two hours before a flight and you’re returning a car, get to the agency 45 minutes to an hour before you must be at the terminal. Better yet, phone the rental agency (the actual local office, not the national tollfree number), and ask exactly how far they are from the terminal, how often shuttles run, and how early they suggest you pick up or drop off your car to make your flight.
