I'm skeptical that air taxis could ever meaningfully reduce traffic congestion to / from JFK. Compared to cars, these would seem to require a significantly larger landing pad and passenger unloading space and need much more safety margin in-between drop offs. Maybe this is competitive vs the private helicopter market?

I wonder what % of traffic is to/from JFK. The subway decently connects much of the city to the JFK air train, but it's a fairly inconvenient journey. Toronto's UP express has made travel to YYZ significantly easier, but I doubt it's possible to construct something similar in NYC.

I love aviation, but I also don't see air travel as being a scalable/affordable solution to this problem. Then again, it's only meant to alleviate traffic burden for a certain segment of the population.

the problem with train it stops ... on every train stop. New york specifically, there are several networks(new jersey, mta, there are lines that are 100+ years old.

In general if you have an affordable enough option you'd never walk into subway, with your several luggages, to travel longer. Train is a decent plan b.

I'm moderately wealthy and lived in New York for a decade. I take the train between JFK and Manhattan. (Specifically, the LIRR.) It's faster, more reliable and–for me–more comfortable than taking a car. (It's also safer.) If I have my cat with me or I feel like having fun, I'll take a Blade, but that's realistically only shaving like 20 minutes off the travel time.

LIRR is not a dirty MTA train :) Noisy shaky helicopter is not an electric taxi with 6+ motors that gives you more stability with way less noise that flies after take of using wings.

Cars for sure are less convenient.

I've also taken the A from Harlem to JFK once. It was fine. Tougher to read a book, like I can on the LIRR, mostly because the frequency of stops means having to constantly be aware of your belongings.

And agree on helicopters. We already have helicopters. Switching them to eVTOLs is a move forward.

if your air taxi is pilotless and electric, why it can't be scalable.

How many people do you think enter/exit JFK arrivals and departures every hour? Where are you going to land all those air vehicles? Is this a shuttle service with many seats? How do you plan for the air traffic for that many people?

[Dylan16807]

About 7000 on average, but let's say 10000 since demand varies. And let's consider doing 10% of them with helicopters. If we average 3 people per helicopter, that's 170 groups in and 170 groups out. If each landing needs 5 minutes of pad time, that's 14 pads. Make it 20 to handle variation.

Wow, that makes it sound significantly more feasible than I would have guessed.

[Archonical]

Where do you put those 20 pads in the city?

[Dylan16807]

I'm not sure but there's a whole lot of city available. That half of the problem is easy on a technical level.

[fragmede]

Those are all reasonable questions, but if some entity would be able to answer them, of all things, I think JFK, an airport, would be well equipped to handle them.

JFK airtrain carries about 30K passengers per weekday in 2025. how many landing pads would be needed to carry a meaningful % of that traffic alone?

[maxdo]

travel time is 5-10 mins with 40 mins to 2hours.

Yes, it is better compared to helicopter. cheaper, less noise. e.g. you can place it more applications, for less money.

[tqi]

Well it's 5-10 minutes once you get to the west 30th st heliport, which can easily take 20 minutes within Manhattan. Plus getting loaded in, cleared for takeoff, and potential for backups at the landing pads, I suspect the gains are much less in practice.

How long does it take to get from a helipad to the terminals at JFK?
