If you're flying from the South Terminal, the Long Stay South Terminal car park is usually the best fit. It's the official airport facility, conveniently located close to the terminal buildings, and handles stays from a few days to several weeks.
On arrival you pass through a barrier that automatically reads your number plate, then park in one of the many available bays. From there, a free shuttle bus runs you into the South Terminal — every 10 to 15 minutes, day and night, with a journey time of around 5–10 minutes. Buses are wheelchair and pushchair friendly.
Security measures across all on-airport car parks include CCTV, regular patrols and perimeter fencing. Booking ahead almost always beats the turn-up rate.
