When wanting to compare parking providers you need to fill out all the needed information our comparison tool needs. This includes the dates that you wish to park. Meaning from the day of your flight till the day you return. Unless you are looking for park, sleep & fly options. Then you will need to factor in when you want to be at the hotel and return. It is important to have the best estimate of when you are going to arrive for all parking types, as this can change pricing. So try be as specific as you can with the times to get the most accurate price.
