What a joke this is , On Friday August 30th we missed our flight to Orlando because of the lack of Immigration Officers . We were at the check in desk for Airtran over two hours before our flight and still missed it ! The line up was very long and there were only three booths open , then eventually six but nowhere near enough to get passengers through in a timely manner . So beware , try and be at the check in three hours before your flight . We learned the hard way.
