Although JFK airport and LaGuardia airport are only 16 km apart if you need to make a transfer between the two, it can add a big chunk of time to your journey. Unfortunately, there is no train that runs from LaGuardia to JFK, so you will need to keep in mind the levels of traffic when travelling.
There are 3 different transport options from JFK to LGA; a taxi, a private shuttle or a bus. Taking a JFK Airport taxi or shuttle or a LaGuardia Airport taxi or shuttle is the quickest but the most expensive option. Taking the New York Express bus is another direct option, which is cheaper than a taxi or private shuttle service, but takes considerably longer.
Welcome Pickups offers meet and greet services and a friendly introduction to New York at the same price as a regular taxi. Click here to see the cost.
