Don't use them for an airport shuttle, PERIOD. Not sure about their other services, but if you are counting on someone to get you to the airport on time, I'd steer clear. At 5pm the day of my flight, I called for 7pm reservation to pick me up for a 9:50pm plane departure. No problem, they said, just be waiting down at the shuttle pickup area at 7pm. I went down as directed, and they still weren't there at 7:15 so I called. Oh, they didn't have anyone on the list for my hotel for a 7:00 pickup. And they won't have anyone available to send by so that I can make my flight. Thanks A NOT! Bad business. Don't trust what they tell you! I ended up taking a different company, they went direct to the airport and I made my flight. Thank you "NOT EXECUTIVE" shuttle company, you are GREAT (but you didn't even have to try hard to out-do Executive).
