Walking from on-airport parking
On-airport parking is the only option where you walk from your car straight to the terminal. At T1, the walk is around five minutes from the nearest bays. At T2 and T3, it is closer — often two minutes. This is the main reason travellers pick on-airport parking for short trips, and the reason to think twice about it if you are moving several suitcases or travelling with small children.
Covered sections are closer to the terminal entrances at both precincts, but they fill first. Open-air bays are further back and usually cheaper. If rain or mobility matters, the covered section is worth the difference.
Off-site shuttles run from the Mascot car parks to the terminal forecourts, typically every 10 to 20 minutes. The journey takes 8 to 15 minutes depending on traffic. On return, you call the operator or wait at the designated pickup point. Shuttle hours vary, so if your flight lands late, confirm the overnight arrangement before you book the bay.
