I am looking to fly from Washington DC airport to JFK terminal 8. I have to catch my Emirates flight in terminal 4 at 2220 on a wednesday. I am looking at tickets and trying to decide if I arrive via American at 1940 will I have enough time to get to Emirates and go through all the security. I will not have a checked bag on either flights, only a carry on. I don't know how often this flight arrives on schedule and welcome any advice!
