UK's Foreign Office advised UK nationals to consider leaving Syria on commercial services, after it upgraded warnings about unrest there (AP, 20-Apr-2011). The Ministry stated it had changed its advice "in light of the deterioration in the security situation in Syria". Britain has not yet considered providing evacuation flights as commercial airlines are still running services as normal.

Brexit and aviation: still no clarity, even as UK government sets timeframe and broad principles
Over seven months after the UK voted in a referendum to leave the European Union, the longer term impact on aviation remains uncertain. The UK Prime Minister Theresa May will almost certainly gain parliamentary authority to trigger Article 50 by her planned deadline of the end of Mar-2017, taking the UK out of the EU by Mar-2019.
On 17-Jan-2017 Mrs May set out 12 principles which will guide the UK in its negotiations with the European Union over the terms of its exit. These principles formed the basis of a White Paper outlining the government's planned approach to the Brexit negotiations. Among other things, the UK does not plan continued membership of the EU Single Market and wishes to control immigration.
There is now a clear timeframe for the Brexit negotiations and a broad framework to guide the UK government in these talks, but still no clarity for aviation. There are obstacles to the UK's continued membership of the European Common Aviation Area, and a bilateral approach may now be more likely. The UK Transport Secretary wants the "best possible access to European aviation markets", but is not yet able to say how that can be achieved.

Europe faces a growing range of geopolitical risks and uncertainties. These range from the presidential election in France and the federal elections in Germany to the UK’s (only) likely triggering of the formal process of leaving the European Union.
