Long TSA lines this summer. The TSA is expecting long lines at their security check points during the busy summer travel season â especially when youâre traveling in the morning. The TSA recommends arriving at the airport at least 2 hours early for domestic travel and 3 hours early for international travel.
Re: How early do I need to get to JFK for International Flight. Feb 08, 2011, 8:12 PM. I would plan to arrive at the airport between 2 and 4 hours in advance of your flight, but at least 2 hours in advance. I prefer to get there as early as possible so not to rush.
