Very disappointing...
I was a little anxious about getting to the airport on Christmas eve. I didn't want to ask a family member or call a cab, I trusted it to the professionals. Unfortunately Manhattan Livery Service are not the professional. I called one week before the flight, I provide a credit card number to book the car service. No one showed up at the agreed upon time on Christmas eve, when I called to follow up I was told I didn't have a booking and there was no car available to get me to the airport.
