Question - moving between terminals at JFK
 

Is the airtrain the only means for moving between terminals at JKF? I have to get from terminal 4 to terminal 7 to make a connection. Thanks.

Basically, yes.

You can always walk! Just curious, why would it matter?

It's a long walk between Terminal 4 and Terminal 7. If you don't want to walk or take the Airtrain (really, it's easy, quick and convenient) your only other option is to take a taxi but that will cost you money you don't have to spend.

Seriously, take the Airtrain!!!
