Typically people buy their airport parking 7-14 days before they fly, the problem is that prices can be higher this way. Ok, so using a voucher code can defiantly save you some cash, but the best way to maximise savings is to book around 60 days before you fly. Prices are typically cheaper on stays that are far in advance and as the car parks fill up they have less spaces to sell so they increase the price. Buying your Liverpool airport parking too close to the departure date can mean you’re paying an increased rate. Our advice is to book as early as you can, ideally as soon as you’ve booked your flight, grab your parking as well. Remember to search around all the different Liverpool airport parking promo codes to get the cheapest price.
