<p>i work near airtrain/subway in queens. 2 large suitcases from airtrain to subway really is one heck of an undertaking. Not familiar with bus to Grand Central- but as I am sure gomestar is correct-- His advise makes the most sense.
-direct bus to Grand central and then Campus bus by Cornell Club.</p>
<p>if timing does’t work then take a taxi to Port Authority from Grand Central and take Shortline/coach bus to Ithaca. Coach bus goes directly to campus. Greyhound takes you to bus terminal in Ithaca not directly to campus. (at least that was how it was a few years back).
Trust me- I am familiar with air train terminal in Jamaica. It’s a real schlep (NY expression) to get from Jamaica to Manhattan via subway with alot of luggage.</p>
