One small catch: Six NYC hotels are offering free helicopter airport transfers into the city.

The congestion pricing plan in New York has been indefinitely postponed, resulting in gridlocked traffic into Manhattan this summer.

Some luxury hotels in the city offer the option to avoid highways for travelers.

From July 1 to Sept. 2, Marriott International Luxury Group is offering free helicopter transfers from John F. Kennedy International Airport and Newark Liberty International Airport.

Reducing transportation time from airports to Manhattan to as little as five minutes is possible through transfers.

Guests staying at least two nights in one of the six Manhattan hotels can take advantage of the flights operated by Blade, the urban air mobility company.

1. The St. Regis New York
2. JW Marriott Essex House New York
3. W New York - Union Square
4. The New York EDITION
5. The Ritz-Carlton New York, NoMad
6. The Luxury Collection Hotel Manhattan Midtown

In Manhattan, there are two helipads where helicopters can land: Blade Lounge East on East 34th Street and Blade Lounge West on West 30th Street, both of which have a car service ready to transport guests to their hotels.

The catch

In order to take advantage of this benefit, guests must book a specific type of suite at those hotels.

The cost of hotel rooms in New York is currently at an all-time high due to the housing of migrants and the prohibition of Airbnb short-term rentals. As a result, Marriott's five-star luxury hotels will be quite expensive.

The "Liberty Suite" at The Ritz-Carlton NoMad usually goes for around $3,500 per night, according to a Marriott representative who spoke to CNBC.

The cost of a round-trip transfer on a Blade helicopter between JFK or Newark Liberty and Manhattan is $390 for the basic fare and $500 for the "Maximum Flexibility Fare." Additionally, ground transportation to and from Blade "lounges," or helipad locations, costs an extra $180, he stated.

Marriott's summer-time perk includes both services, according to the representative.

Guests staying in rooms, rather than suites, in one of the six named hotels can still take advantage of discounts on Blade's services this summer, the representative stated.

In 2019, Blade launched on-demand helicopter services to New York-area airports, preceding Uber Copter's launch by several months. Both services enable travelers to book rides through apps. At the time, a single seat on a Blade transport service cost $195.

Uber Copter ceased operating in 2020.
