The simple answer is yes. Airport parking does tend to get more expensive closer to the time, so we always recommend booking in advance (the earlier the better) to save yourself from unnecessary price jumps. At Gatwick for example, 1 weeks parking at Purple Parking Park and Ride, when booked in advance, can cost as little as £4.25 p/d, however when booked closer to the time of your departure date, it can cost around £14 p/d.
