No. As far as I know, there is no bus, either. I cannot find any mention of one on the MTA's website (Metro Transit Authority, which is New York State's transit authority, and of which the NYCTA - New York City Transit Authority - is a subdivision).
A taxi is by far the simplest and easiest way to get between these two airports. However, some airlines may offer bus or shuttle services. Try calling your airline's customer service number.
You can also use Super Shuttle (1-800-BLUE-VAN).
No, take a cab.
LGA is closer.
JFK serves different airlines than LGA. JFK also is bigger, and there are more flights coming in per hour than LGA, as far as that goes, it is nicer.
JFK is closer.
No airlines flies direct from JFK to MKE. Try LGA and EWR.
JFK: Delta, JetBlue LGA: Frontier, United EWR: Continental, United
If you're asking how to get from LaGuarda to JFK, he best way to get to JFK from LGA is by taxi. A yellow taxi line outside all terminals at LGA is the fastest or you can call a private taxi service to pick you up. I shuttle between both airports a lot and I use Kew Garden Taxi. Just call them and they will pick you up in a matter of minutes for a flat fee. Their phone number is (718) 846-5800. Hope this helps. If you're asking if the International JFK Hotel, a hotel near JFK, offers shuttle service to LGA, you'll really just need to call them and ask.
Well the lowest price is 845 dollars per person for jfk lowest price for lga is 765 dollars your better off flying into lga but it is deltas hub so there are a lot of flights

Use a subway or a bus, or even walk to save money.
JFK recorded 2.3" while LGA picked up 3.5". Those seemed to be at the two ends of the spectrum in Queens.
In the range of 16 - 18 inches. LGA officially recorded 17.3" while JFK came in at only 10.3", but I suspect that is low.
