the legal req. for breaks is 3.5 hours, we normally get more depends on how long the first service takes, the second service doesnt req. all crew so normally the the first crew do the service and the second clear, then everyone is up for the last service, however for a dxb-jfk the main meal service is in the middle so you have to have all crew up, there are 14 crew, 6y 4j 4f
