Dense smog engulfed the Lahore airport on Monday night, forcing the authorities to completely suspend the flight operation.

Visibility at the airport reduced to zero at around 9:30pm on Monday night. A spokesman for the PIA said that due to smog prevailing in the country some of PIA flights operating on Tuesday and Wednesday had been rescheduled and some cancelled. He said that some flights have been revised for Tuesday 7 November due to weather conditions, including PK 582, PK 583 Karachi-Rahim Yar Khan-Karachi, PK 390, PK391 Karachi-Sukkur-Islamabad-Sukkur-Karachi, PK 588, PK589 for the sectors Karachi-Bahawalpur-Karachi, have been cancelled.

Meanwhile, following flights have been revised for Wednesday 8 November due to expected adverse weather conditions: PK 582, PK 583 Karachi-Rahim Yar Khan-Lahore-Rahim Yar Khan-Karachi will now be operated as Karachi-Lahore-Karachi.

The PIA spokesman said that weather conditions are expected to prevail for the next few days and are beyond the control of the airline. The PIA has to adjust timings of its flights due to such weather conditions, as the airline cannot operate flights with poor visibility keeping in view the safety requirements. This results in either cancellation of flights or flights operated with delays.

The passengers are being informed by PIA Call Centre. However, the passengers can also confirm the revised timings of their flights before reaching airports from PIA call centre at 111-786-786. PIA regrets the inconvenience caused to its passengers, the PIA spokesman concluded.
