UK-based airlines told to move to Europe after Brexit or lose major routes MSN/The Guardian
From Saga Magazine - Flight price changes and the EU ‘open skies’ agreement
"Regardless of the type of holiday you take, whether it’s a package or you book independently, all UK holidaymakers who fly overseas may suffer in the future if flight prices increase. And this may well happen as a result of Brexit. The UK will need to renegotiate the ‘open skies’ agreement with the EU, which has allowed all EU airlines to fly between any two points in Europe. This freedom has enabled no-frills airlines, such as EasyJet and Ryanair, to flourish, and this has forced other airlines including British Airways to cut the cost of their fares. As a result, flights around Europe are significantly lower than they were in the early 1990s. In two years’ time though, having access to cheap fares may be a distant memory. It will all depend on whether the UK government decide to introduce their own aviation laws and negotiate their own deals. New agreements will also have to be made with the US. Currently, as a EU member state, carriers from the UK can freely fly to and from the States under the EU-US open skies agreement. This is all subject to change".
