Because our cars belong to real people, they're parked where real people park. This means we don't have any cars at airports.
However, we do have cars within a few kilometres of the airports in all the cities in which we operate. You might like to book one of these for your holiday and get to it by taxi, Uber or public transport.
Cars need to be picked up and returned to the same place, so you can't drive to the airport and leave the car there. You would need to return the car to its homezone and travel from there to the airport.
