Loganair sent out messages to would-be passengers this afternoon (Friday May 10th)  warning of "HIAL Industrial Action: Stornoway Flight Cancellations" on Monday and Tuesday 13th/14th May. 

They say that "due to ongoing industrial action by HIAL air traffic control, we regret to advise that the following flights to and from Stornoway have been cancelled on 13th and 14th May."

A spokesperson for Highlands and Islands Airports said: “There will be times when tactical closures at airports are required in order to comply with regulatory requirements governing controller working hours.

"We apologise for any inconvenience that the added restrictions of the work-to-rule place on customers at this time.”

These cancellations are in additions to ones expected the following week on the day of the all-out air traffic control strike, Thursday May 23.  They are for staffing reasons relating to the current work-to-rule – there are Air Traffic Control shifts that would normally have been filled through overtime or shift swaps, which are precluded by the work-to rule.  The timing of the missing shifts is such that subsequent flights would have to run late – outside normal operating hours – which is not allowed by the work-to-rule, so none of the flights can operate.

Loganair added that other services to and from Stornoway on Monday and Tuesday may be subject to delays dependent on circumstances prevailing on the day.

Flights cancelled are:

Monday 13 May
• LM478 Glasgow-Stornoway,
• LM479 Stornoway-Glasgow.

Tuesday 14 May
• LM341 Edinburgh-Stornoway,
• LM342 Stornoway-Edinburgh,
• LM478 Glasgow-Stornoway,
• LM479 Stornoway-Glasgow.

"Customers on impacted flights may elect to travel earlier on Sunday 12th May or postpone travel until Sunday 19th May (subject to seat availability). There will be no charge payable (i.e. the usual change fees plus any difference in fare will be waived for all ticket types).

"If your journey involves a connection with another airline, we, unfortunately, cannot guarantee that other airlines will offer the same flexibility to change tickets.

"We recommend that customers check with the second airline around their onward travel.

"Alternatively, if you elect not to travel, you can request a refund may be taken for any journey or part of a journey not used.

"Loganair can only ask for customers' understanding that the situation is entirely beyond our control and we regret the inconvenience that this will undoubtedly cause to our customers."
