Amongst the social media complaints is one claiming 15 or so STN-bound pax were denied boarding in Malaga after being late to the gate because of a long queue at check-in. Online check-in is not offered on STN routes.
On the the plus side, the flight was apparently very full. On the downside, this sounds like something totally within the airline’s control and more bad publicity that could easily be avoided.
What is the situation with compensation in this scenario, assuming the pax did genuinely arrive at check-in with good time which I have no reason to doubt?
