The data for a Flight (The transaction entity) will contain at least the following: Plane ID (Tail number) Number of Pilots (flights over 8 hours require 2 pilots and 2 co-pilots) Number of Cabin Crew (flights over 8 hours require double the minimum) List of Pilot IDs List of Cabin Crew IDs Start Date/Time (in GMT) End Date/Time (in GMT) Starting Airport code (3 letters)
