Some car parks sell out much more quickly than others, particularly on-site parks close to the airport terminal. These are usually the most expensive and they generally only become more expensive the longer you wait to make your booking. If you reserve your space several weeks, or ideally several months in advance, you'll probably notice a discount on the cost of car parking. Plus, you can often take advantage of additional discounts offered by parking operators. On top of that, when you book in advance that's one more thing ticked off the list, and one less thing to pay for as your holiday draws near.
As for how to book car parking, you can go direct to the airport and book online via their website, or you can use a third party operator. Off-site car parks are generally all managed by third party operators, but you can also use these companies to book on-site parking too. For instance, if you need car parking at Manchester Airport, you can book this through Thomas Cook Extras. Thomas Cook is one of the best-known and most trusted names in travel, so when you book with them you can expect a straightforward booking process, quality parking and a high level of security. They also offer a price promise, so you can expect the best value too.
However and wherever you book, make sure you do it as soon as possible and well in advance of your departure date. It's one less thing to think about, so all you have to do is jet off and enjoy your time away.
