If this was last nights flight from EZE to JFK, there were three Non-Revs in first and 2 in business and what appears to be 5 unassigned seats in Biz and 3 unassigned in first.... I don't think the accuracy of this statement is totally correct. And these FAs could have been dead heading back from their last flight. They ARE humans and should be allowed to sleep at times. OR they were flying to catch their next long haul flight and needed to sleep. The DYKWIA stigma in here is overwhelming.
