As soon as your plans are fairly definite, just give us a call or send us an email to set up your reservation. We always suggest as much notice as possible, several days for airport service and at least two weeks for most hourly charters. Seasonal, off-hour and special events may dictate more notice, sometimes even a few months, so try to plan accordingly. That said, just contact us whenever you are ready and need service, same day, same week, or even within the hour.
