As talk of redrawing maps and shifting currencies escalates, uncertainty in the travel industry is a given. What happens to border control rules for business and leisure travelers? Visas for expatriate workers? Will United Kingdom-based airlines remain subject to EU regulations? Will U.K. citizens maintain EU passenger rights protections? Will Open Skies agreements with the United States be extended to the United Kingdom? How will new trade agreements affect business travel demand overall? All of these questions have to be answered as Britain negotiates its exit terms. EU officials said they are ready to start unwinding the United Kingdom from its membership, invoking Article 50 of the Treaty of Lisbon, which lays out a two-year timeline for separation. For the moment, however, travel process and route access changes are not imminent, according to government officials. "There will be no initial change in the way our people can travel, in the way our goods can move or the way our services can be sold," Cameron reassured the British public immediately following the referendum results. That's the message travel management companies are driving home to their clients, as well. American Express GBT issued the following statement this morning: "Following the UK's decision to exit the European Union, it is important for the business travel community to remember that nothing is going to change overnight. The EU, the UK and our sector are now facing a period of uncertainty. There will be a prolonged period of negotiating the UK's exit from the EU, during which time we expect conditions for travelers to remain the same."
