Few sites are exposed to the elements with such regularity, yet almost all find it hard to compete with Oslo's record on punctuality.
Around 40 percent of flights were cancelled at Paris Charles de Gaulle and Orly airports on just one day in January this year.
Frankfurt meanwhile was forced to close operations, leading to the cancellation of some 500 flights in the process.
By comparison Oslo has only ever had to cease operations because of heavy snow twice since opening its doors in 1998.
On both occasions operations were up and running again after a matter of hours -- although Oslo Airport is considerably smaller than those in London, Paris and Frankfurt.
"I think it's fair to say that after fourteen years we are in the position where we have a very solid and very good operation," says Nilsen.
"We are well prepared, know how to handle the situation and we also have a policy of standardizing the fleet of vehicles so maintenance and renewal is much more easy.
"(But) we know that one winter will always play different from the previous ones so we (will always) learn something new," he added.
