I use this parking company all the time and travel 3 - 4 times a year. I know, however, that I have to add a good 30 minutes to my travel time because it will easily take you 20+ minutes to get to the airport from the moment you park you car. I've seen many a panicked person, late for a check-in or flight, on these shuttles. I used to be that person and it took me 2 or 3 panic sessions to learn. If you don't have the extra time I recommend you use Uber or Lyft, instead. I have learned to adjust and make the decision based on available time. If you have the time, they are a reliable company. There are multiple shuttles (I've seen two, for sure) between the parking lot and the airport. I've only had to call for shuttle twice as they are typically onsite at the airport, or drive up faster than I can call (maybe just my good luck). I downloaded their app so I can schedule my parking time and pay for it, too. I can use the app to check in and see my history. Very handy!
