 Staff there apparently proved quite adaptable and they went all old fashioned and started writing out boarding passes with a pen and handing them out to passengers when they couldn't print them. I do want to give particular mention to Wizz Air. They say they're facing extreme technical challenges. I should explain. Wizz Air famously has one of the worst punctuality rates in Europe. It's regularly slated. So I think it's possible that Wizz Air passengers won't actually notice today's disruption. They'll probably think it's just another regular day.
