KARACHI (PR) - Pakistan Airline Pilots Association (PALPA) has again resorted to unlawful go-slow policy in an effort to disrupt the flight schedule of PIA to pressurise and dictate the airline management to accommodate their unjust requests, PIA spokesman said here on Tuesday. Palpa has a long history of pressurising the PIA managements in the past as well. But for the first time the national flag carrier is being managed by the professional management of PIA veteran pilots not crumbling under Palpa pressure by maintaining the flight schedule to avoid discomfort to the passengers. However, some flights were delayed due to last minute refusal of Palpa activist pilots to perform their roster duty, decided in advance on monthly basis. Since last Saturday, 35 Captains and First Officers under Palpa pressure have avoided operating flights at the last minute.
