Passengers travelling via international hub airports, and who remain in the transit area, typically need only need to meet the red tape requirements for their final destination. But KLM has a policy on documentation that means many UK travellers could inadvertently be denied travel via Amsterdam.
Standard practice for big Continental hubs such as Frankfurt, Paris CDG and Copenhagen is that passengers making connections between “non-Schengen” nations – such as UK to US or India to Canada – do not need documentation entitling them to go through passport control into the EU.
