New York is a Delta Air Lines hub, so Delta Air Lines typically offers several daily departures on NYC–DEN, with nonstop service where demand supports it and connections through its other hubs otherwise. The nonstop flight time is about 3h 42m.
Fare classes available: Basic Economy, Main Cabin, Comfort+, First Class / Delta One. Delta removed change fees on Main Cabin and above for travel originating in the US, Canada, Europe, Africa, and the Caribbean. You pay only the fare difference, and if the new flight is cheaper the difference is returned as an eCredit.
The lowest one-way fare we have on record for this route is $245, and $386 round-trip. Fares like that usually show up on off-peak days and for travel booked a few weeks out; an agent can check whether a similar fare is available for your dates.
Because Delta Air Lines treats New York as a hub, this pairing tends to have frequent departures throughout the day. American Airlines and Southwest Airlines also compete here, which keeps fares in check.
At 1,622 miles and about 3h 42m nonstop, this is a long domestic sector where the choice of airline matters for comfort: seat pitch, Wi-Fi, and a meal option vary more than the fare does. Overnight and first-departure flights are usually cheapest.
Winter fares out of the Northeast peak around the holidays and February school breaks; late April to early June and September to early November are usually the calmest on price.
Tuesday, Wednesday, and Saturday departures are usually the cheapest days on domestic routes; Friday and Sunday are the most expensive. Early-morning and late-evening flights are often priced below the midday departures.
For domestic travel, booking three to eight weeks ahead usually captures the best price. Inside two weeks, fares climb; more than four months out, airlines have not yet released their cheapest inventory.
The same city pair priced from each airport combination. Differences on the same day are often larger than the drive between airports.
Fares from a neighboring airport are sometimes far lower than the drive is long. Agents quote all of these on one call.
