Having been severely burned on two occasions by taxis booked for a flight, which didn't show up, and the dispatcher not caring at all and telling me another car would come in "45-60 minutes", by which time I would no longer need to go to the airport as my flight would have left without me... Well, I would trust pretty much any other option before I would ever try to use a traditional cab for an early morning airport trip again.
