I apologize for not giving much info. I will be coming by Emirates from India which lands at 8:30 and then I have a jetblue connecting at 13:50 to MCO. This is in July 2013 and I am pre-planner, hence I am asking now. Sorry for it.

I said 10:30 to cover up the Immigration, baggage etc.
I was planning on giving my hand luggage in storage which I saw is available in jfk.

If it is that much hassle, I would not go then.

Thanks for all the information. I thought it would be a breeze using the trains. LOL
