DELAY ZY




As for 'Z CODES' I haven't the foggiest for ZY. The Z codes break down delays by department, and are further sub divided with three letter codes. However for reference;

ZA - ATC

ZC - CARGO

ZD - SECURITY

ZE - ENGINEERING

ZF - FLIGHT CREW

ZJ - INFORMATION MANAGEMENT (IT)

ZK - CABIN CREW

ZL - GROUND FLEET SERVICES

ZM - CATERING

ZO - OPERATIONS

ZP - PASSENGER SERVICES

ZR - RAMP

ZT - AIRPORT CENTRE (think load control/load sheets etc)

ZW - WEATHER (Micheal Fish gets his very own hurricane/not hurricane code)

ZZ - AIRPORT AND AUTHORITIES.


As for the actual delay on the flight, that was down to ATC with a TSAT or start up delay.
