When booking flights from Belgium (Brussels), Iberia redirects to its Belgian website. There you have to make a language selection and you can choose between French or English. French is indeed spoken by about 40% of the Belgians, English is not an official language in Belgium. There is no possibility to select Dutch as language although Dutch is the official language of 60% of the Belgians (Flemish part of Belgium). The Dutch language can be chosen though if one goes to the Iberia website of The Netherlands (flights from Amsterdam). Is it unique and limited to Belgium for Iberia not to communicate in the major language of a country?
