Advance reservations are required and must be secured by a Visa or MasterCard. You are,of course, not charged for flights canceled because of inclement weather. Should you fail to show up at the scheduled meeting time, or cancel less than 48 hours in advance of our meeting time, the full flight fare will be due. Cancellations or reservation changes of less than 48 hours prior to the meeting time are not permitted. I prefer a much greater notice, as I am informing customers that dates are filling up a week in advance. I do keep a list of stand-by customers, and will make every attempt to fill your spot so you will not be charged.
