LAHORE - Foreseeing the expected shortage of fuel in the City, PSO authorities have asked the airlines to have their fuels from Karachi and Special Flights used in VVIP movement to have the same from the base because PSO was facing problems due to the wheel jam strike of oil tanker owners in Sindh, sources in CAA said here on Thursday. They said that as the oil tankers association have gone on strike for the last couple of weeks and earlier this strike was within Sindh province then up to Karachi while now it has been restricted to the PSO's hub and tankers cannot move here and there from that hub. The PSO authorities have advised the airlines staff to pick up fuel from Karachi instead of Lahore they have also advised all scheduled flights to take only 'sector fuel' (up to first destination) and more fuel they could have from the next destination during transit flight. PSO was discouraging to provide fuel to non-scheduled and even scheduled flights, which are touching Karachi on their arrival or departure and they were being asked to get fuel from Karachi. An official of PSO said that they have written to the Special flights operators to fuel their planes from the base from where they were going to operate. It is worth mentioning here that through special flights only VVIP figures of the country travel. To a question that how long the crisis could prolong, a PSO official said that it could be ended any time as the negotiation between Oil Tankers Owners and Logistic Department of PSO was underway in Headquarter. Hopefully we would reach to any solution in this regard, he added. When contacted, Airport Manager Allama Iqbal International Airport, Syed Aamir Mehboob said that here was no shortage of the fuel at the airport and the airlines were warned by PSO only to be on safer side as strike of Oil Tanker Owners was underway and they were asked to pick up fuel from Karachi.
