I had my first experience at Blue Sky this week and it was excellent. I was running late for my flight and thought that the garage adjacent to Terminal 4 might save precious time (but cost more). I pulled into Blue Sky, parked, was immediately picked up by the shuttle and had my bag checked in at Southwest about 10 minutes later. It was unbelievably easy and smooth. It actually would have taken longer to get to the garage at Terminal 4, find a parking place and carry my luggage to the elevator and then to check in. I will never use the garage again. Blue Sky every time for me!
