Have been stuck in NYC for a while due to the hurricane, latest snag was many car services either didnt have cars available or wouldnt take reservations due to gas shortage. Uber is even charging "surge" pricing. Went down the list, elite, limores, dial7, ended up with carmel. Carmel has mixed to bad reviews on here and on yelp, so booked them a little early in case I had to scramble for another car. Driver was prompt and didnt drive crazy, unlike most mid/low end car services here. They probably have their share of bad drivers, but this trip to JFK was fine.
Bonus - they give a few AA or Delta miles.
