Fair Fare

What a trip should cost by taxi, Uber or Lyft. Distance and time by road between two places, the licensed taxi meter fare with the extras that apply at that hour, any airport flat fare, typical Uber and Lyft prices in New York, airport pickup rules, a pre-booked transfer option for airport trips, and links that open Uber, Lyft or public transport directions with the trip filled in.

Was I overcharged? Check a fare that was paid. Compares what was paid with the official meter tariff, the airport flat fare or New York's typical Uber and Lyft prices for the same trip and hour, gives a verdict (fair, high or overcharged), the next steps for that company or city regulator, and a short message to send asking for a refund.
