Well in that case I reckon Jet2 should drop all their canaries flights, we saw how much hassle it caused back in '77 when Las Palmas got closed and all those aircraft were diverted
Plus Jet2 fly to the canaries much more regularly, with larger aircraft, which must hugely increase the chances of large amounts of disruption in the event of bad weather
Come on... Really? If it was that bad, why would anyone fly into Funchal at all? Or any other challenging airports for that matter
