This week, UK Members of Parliament have voted overwhelmingly in favour of invoking Article 50 to leave the European Union.
It is now more than half a year since Britain voted to leave the EU but what effect has this had on what travel buyers are experiencing as a result of the decision to Brexit?
A recent study for the Business Travel Show decided to find out. It asked 178 travel buyers — 61% of whom work in the UK, "What impact will Brexit have on client confidence and buying behaviours?"
80% of buyers surveyed in the UK and 83% in continental Europe said it was "business as usual".
However, the study also found that some buyers are noticing price increases, as our chart shows.

Rosy Burnie, travel advisor and former global HQ office manager for manufacturing firm Luvata: "Currently, it's business as usual. The world is bigger than Brexit. However, the uncertainty means that future investment projects go on hold."
The percentage of buyers saying they have experienced increased prices is perhaps lower than might be expected given the state of sterling. The chart below shows how the pound has fared against both the euro and US dollar over the past year. The Brexit cliff in June 2016 is clearly visible and the pound is now trading 10 to 11% lower against the two currencies year-on-year.

With many aspects of travel linked to the dollar and much business travel spending in the dollar and euro zones, sterling's fall will feed through sooner or later.
