Around 20 minutes before you arrive at the airport, please call to let them know you're on your way. Once you're at London City airport, drive to the Terminal Car Park. Once there you will come to 3 barriers take the one on the extreme left and take a ticket to get in, drive through and park your car in a space. A suited driver will meet you and you will need to give them your keys and the ticket from the barrier. All you will need to do then, is take a short stroll to check-in.
