I have just used this brand new (to Calgary) service and it was fantastic. Most affordable option. No shuttles. Help getting bags out of my car when dropped off (in my own car) right at the terminal. A warm car to pick me up when I got home. Arrived in less than 10 minutes from my phone call. Both drivers I met were super friendly and I felt completely comfortable. I was travelling as a woman alone. This service would also be amazing with my toddler in the carseat because I wouldn't have to get him in and out and figure out how to pack a car seat into a cab or haul it into a shuttle. Best parking option for flying. Period. And if I wanted to pay the extra to have the full valet experience, it would still have cost me less in total than a cab from home one way! (I live about 40 minutes from the airport).
And there's an easy to use app too.
Thanks boys. You've got a great business model. Good luck!
