Do I have to provide my flight number?

Correct timing on an arrival transfer depends entirely on flight information; without your flight number we direct the driver according to the time on the booking, with no way to adjust for a delay or early landing. That risks waiting for you and mistiming for the driver. On the return leg from a hotel to the airport, the flight number is optional — sharing it still helps, since we can alert you if the flight is cancelled or rescheduled. You can also send your flight number to us via WhatsApp later.
