I used Elite,
www.eliteny.com for airport transfer JFK into midtown NYC & have to say it was the best airport service I have experienced in last 10 years, especially for the $$ spent. Car was new, spotless, with on-time, courteous, good driver. Flat rate was $73 + taxes, tolls & tip. Signed up & booked on-line. Received instant booking confirmation & phone service/calls later were answered quickly, with swift resolve.
Had a few special issues:
1) both to/from were during commuter rush hours (am in, pm out) and ride was comfortable & driver knew & used alternate routes when able.
2) we had 2 passengers, both at same time but different p/u & drop off airport terminals - no problems & no extra charge.
3) left an item in car & it was found & is being returned.
All in all, very pleased with this new (to me) car service for NYC area & will definitely be using them again!
