KLM is the Dutch national carrier and one of Europe's most Brompton-friendly full-service airlines. Based at Amsterdam Schiphol — a city that lives on two wheels — KLM handles folding bikes with efficiency that reflects the Netherlands' cycling culture. The bike travels as sports equipment for a fee of approximately €30–50 depending on the route. Schiphol is one of the best airports in Europe to arrive on a folding bike — exit the terminal and you are on dedicated cycling infrastructure within minutes. Amsterdam to virtually anywhere in Europe on KLM with a Brompton is a genuinely great travel option.
