Q. Is there a shuttle bus from LaGuardia, NY airport to JFK, NY airport? If so, what is the cost, and how long does it take?
A. There's the New York Airport Service which costs $13 and takes about 45 minutes. These leave every half hour and can be caught right outside the terminal, along with other ground transportation.
And if you're in a rush, you can always get a cab from the taxi dispatcher. From LaGuardia to JFK, you're looking at a fare of $25 to $29, and it should only take you about a half hour to get there.
