New York Denver
United, Delta, JetBlue, Frontier, and Spirit all fly New York to Denver nonstop. About four and a half hours. Departures run from all three New York airports throughout the day.
If you are going skiing, read the rest of this page before booking. Denver is two hours from most ski resorts by car, and that drive through the mountains in winter is not casual. Aspen has its own airport (ASE) with nonstop service from JFK on American and United, but ASE sits in a valley and weather cancellations are common. Eagle County (EGE) serves Vail and Beaver Creek with a shorter, less dramatic approach. Both mountain airports cost more than Denver but save you the drive.
If Denver itself is your destination — or if you are renting a car and driving to the mountains on your own schedule — fly into DEN on United for the most options or Frontier for the lowest fares. JetBlue from JFK puts an A321neo on the route with a better cabin than Frontier or Spirit. From Newark, United dominates. From LaGuardia, Delta and Frontier split the traffic.
Denver airport is 25 miles northeast of downtown. The A Line commuter train runs from the airport to Union Station in 37 minutes for around $10. Uber works but can surge during ski season weekends.

Connecting through New York from a domestic flight
Denver as a western US hub. United runs a massive hub at DEN connecting to every mountain west city. If your final destination is Salt Lake City, Boise, Albuquerque, or smaller Colorado cities, Denver is the natural connecting point from New York.
Direct to ski resorts. American and United fly JFK nonstop to Aspen (ASE) and Eagle/Vail (EGE) seasonally. These flights are more expensive and weather-risky but eliminate the mountain drive. Book refundable if possible — ASE cancellations are common.
New York & Denver Airport Profiles
Each airport has a personality. Terminal quality, transit access, lounge scene, and crowd levels vary dramatically — sometimes more than the flight itself.
New York Metro
JFK spreads across four active passenger terminals connected by the AirTrain, and walking between them is not an option. Terminal 1 is the old international building. Terminal 4 is the largest, handling most international carriers. Terminal 5 is the former TWA terminal, now JetBlue's home, with the mid-century curves still intact. Terminal 8 belongs to American and British Airways.
The terminal you depart from depends entirely on your airline. Security wait times vary between them. Terminal 4 tends to be the slowest during evening international departures. Terminal 8 has improved since the co-location of its two main carriers. The TWA Hotel sits adjacent to Terminal 5 if you need to sleep before an early departure or after a late arrival.
JFK feels enormous because it is. Budget extra time for the AirTrain if you are connecting between terminals or arriving by subway. The AirTrain loop takes 10 to 15 minutes end to end.
LaGuardia is the New York airport that does not pretend to be anything more than a domestic terminal. No international flights, no customs hall, no transatlantic gates competing for security lane capacity. The result is a faster, simpler airport experience than JFK or Newark for any flight that stays in the country. Eight miles from midtown Manhattan, it is also the closest major airport to the city center.
The rebuilt Terminal B replaced what was widely considered the worst major terminal in the country. The new building is bright and open, with real restaurants instead of the food court that used to define LaGuardia dining. Gates connect via an elevated pedestrian bridge with a clear sightline to the Manhattan skyline. Terminal C is equally compact. Neither terminal is large, and gate-to-gate walks stay under ten minutes.
Newark Liberty has three terminals, and Terminal A opened as a full rebuild in 2023. The old Terminal A was demolished and replaced, and the difference is dramatic. Terminal C is United's hub, massive and busy, with most international flights departing from here. Terminal B handles most other carriers.
The AirTrain connects all three terminals and the NJ Transit / Amtrak rail station. Unlike JFK, the terminals are closer together and the AirTrain loop is faster. Security at Terminal C can back up during afternoon and evening international departures.
The airport sits in New Jersey, around 10 miles from Manhattan. That proximity is deceptive because the drive crosses the Hudson via the Newark Bay or Lincoln Tunnel, and both can be brutal during peak hours. NJ Transit from Penn Station is the more reliable option.
Denver Metro
Denver International Airport (DEN). 350 weekly nonstop flights from New York.
Which Airlines Fly Which Pairs
United Airlines serve both EWR and LGA to DEN — airport flexibility on the New York side.
Not all planes are the same size. The aircraft type below each checkmark tells you whether you are getting a widebody (777, 787, A350) with wider seats and a quieter ride, or a narrowbody (737, A321) with a single aisle. On flights over five hours, the difference is significant.
