You'd have to do it on separate tickets. No airline is crazy enough to sell a 1/1.5 hour D-I LGA-JFK transfer.

Like any close connection, the real question to ask is, how bad is it if you miss it? If there's a later flight the same day then it's probably not worth worrying too much about (unless you are in J/F and are worried that you will be reaccomodated in a lower class of service)

If it's a big problem if you miss it then push them to reschedule you. It's not uncommon to have your first flight be delayed by 20-30 min, and then not unheard of have to wait another 30-40 min for checked bags.

I think he's talking door to door as in terminal to terminal. 1.5 is about the time it took me - perhaps even less.

which bus to which subway station and which line?

ok, I found my old notes in this thread:

https://www.flyertalk.com/forum/new-...jfk-lga-3.html

Took a little over an hour door to door.

Q70 bus (it's now free) from LGA to Roosevelt Avenue/Jackson Heights subway station. Jamaica-Center-bound "E" train from there to Sutphin/Archer/JFK Station, for connection to the JFK AirTrain.

Caution: During the weekday evening rush hour, a few Jamaica-bound "E" trains do not go to Jamaica Center, but go to 179th Street/Hillside Avenue instead. The 179th Street-bound "E" trains do not serve the Sutphin/Archer/JFK station. You can download an "E" train schedule here:

One caution on this: if you have a ton of luggage, this could be a pain. If you have one rollalong bag (either carry on or check) and a backpack or hand bag, this is very doable.

LGA TO JFK connection - enough time?
 

I need to travel last minute and with what options that were left, I will be flying DTW - LGA on AA arriving at 11.55am and connecting to ATH from JFK on AA at 5.30pm (midweek).
Im looking for some reassurance that 5 1/2 hours will be sufficient time to get from one airport to the other (assuming on time flights) as I am stressing out about it. I will have checked baggage and am planning on taking a cab from LGA arrivals to JFK departures.
Thanks in advance!

That should be more than enough time.

If both flights are on a single PNR, then AA is obligated to protect you in the event that IROPS causes you to misconnect at JFK.

The flights are on a single ticket, and I have a hotel booking in ATH so really hoping that 5.5hrs is sufficient time for connection. Thanks for your reply!

You will be traveling in between rush hours, so you should have plenty of time. I’ve made it LGA to EWR in an Uber during rush hour in far less.

The taxi ride from LGA to JFK will probably take 30-60 minutes, so even if you do not collect your baggage at LGA until 1:00 pm, you'll still have plenty of time to make your connection.

They are 10 miles apart. That’s way more than enough time. Take the Q70 bus to Roosevelt Avenue, take the E train from there to the JFK subway stop and take the Airtrain the rest of the way. Or take a Lyft/Uber.

Thanks - Im feeling better now about it!

Q70 -> E train (Kew Garden stop) -> Q10 -> Airtrain
Be even more adventurous, and save money in the process. the above routing will only cost $2.75
