This is a new one for me:
We’re really sorry to inform you that due to expected industrial action by ground handlers at Oslo airport, like other airlines on 27th May, we may not be able to accept checked baggage on your flight.As negotiations remain ongoing between trade unions and the ground handler, our teams will continue to monitor and seek clarification. Rest assured we will be in touch as soon as we have an update.
Please may we ask that, if possible, you travel with hand-baggage only to avoid any disruption to your journey.
What is the protocol here? Do you check your bag at LHR and then hope for the best? It might be loaded or I guess it might come a few days later?
