The Brexit negotiations are encountering all kinds of stumbling blocks despite an already tight timeframe. In fact, the negotiations on the details of the Brexit deal haven’t even begun. This is a concern for the tourism industry because it has to be aware of the terms of that deal to be able to plan for the 2019 summer season. Negotiations on key issues have to commence soon, especially the complex issue of aviation. This is predominantly in the interest of countries in the south of the European Union which are highly dependent on British tourists. Almost one in four holidaymakers in Spain comes from the United Kingdom.
