Reserve parking online to not only secure a spot in the lot but also to get discounted pricing. It was so easy to do ahead of time and then when at the airport parking lot you scan the QR code received via email both upon entering and exiting the lot. If you chose extended parking, you can use the people movers in the airport to get to the airline booths quicker. The walk is reasonable and the pricing is reasonable.
Would give 0 stars if I could. Customer service was extremely unhelpful and hung up on me while I was lost. Save yourself the trouble and just use a parking garage.
