What does the Brexit mean for travel to the United Kingdom? Well, although the final agreement is still months or years away, the uncertainty surrounding the issue has resulted in the English Pound falling by ten percent against the US Dollar. It's probably fair to suggest that the Brexit would result in less foreign investment in the UK, and therefore a lower Pound. How far the currency will continue to fall is an open question.
I must admit, I was shocked, like the rest of the world, that the Brexit referendum was successful. Certainly, the comedian John Oliver had a strong opinion against the Brexit (see below)
Humour aside, we should recognise that the United Kingdom is a sovereign state and the will of the people should be respected. Having said that I'm not confident that a 'Full Brexit' will actually ever occur due to the economic consequences. It's the uncertainty over the final agreement, and business hate uncertainty that is driving the current financial volatility.
In conclusion, my prediction (for what it's worth) is that the English Pound should remain lower (between 10-20%) against the US Dollar until the final situation regarding the Brexit is worked out. A full Brexit would entail the UK negotiating it's cheap airline carriers access to the EU for instance, and other travel related issues like visas etc.
Until the final details are negotiated it should be relatively cheaper to travel to the United Kingdom.
