Once you complete your booking, you will be issued a voucher with full instructions on how to meet your driver and where he/she will be waiting for you.
Some airports have reception desks, at other airports the driver will meet in the arrival hall, at other airports you may be requested to go to the coach bays (usually group bookings). Each supplier at each airport has a different set of instructions. These instructions are integrated clearly into your booking voucher and include all details you need to make your transfer hassle free.
You will also have 24 hour telephone contacts issued on the voucher in the event that you should still have problems finding your driver
