If we do not have the correct flight arrival number we cannot track your flight.  It is a common occurrence for flights to be delayed, early and sometimes diverted or cancelled.    When these events occur, we adjust your pickup time automatically so you do not have to worry about a driver being there for you.  However, if we only have a time to show up and no flight number to check, additional wait time charges will apply after 45 minutes and after waiting too long the driver will be released from the call.  This can be avoided if we have the correct flight arrival number and the correct passenger cell phone number.  Please ensure this information is on your reservation confirmations.
