Estimating the impact of recent terrorist attacks in Western Europe The terrorist attacks in Western Europe in late-2015 and early-2016 reduced European airlines’ international passenger traffic by an estimated 1.6% in the following year compared to what would otherwise have happened. We estimate that this reduced European airlines’ 2016 revenues by around US$2.5bln. Nonetheless, by contrast to previous major shock events such as after 9/11, the impact has been only temporary. European carriers were hit the hardest Europe has since fully recovered back to its ‘pre-attacks’ The most visible impact of the terrorist attacks in trend level. Western Europe in late-2015 and early-2016 was on A negative, but temporary, impact on passenger traffic, international RPKs flown by European carriers; such revenues, and profits traffic fell below its trend level following the Paris attacks Overall, we estimate that European airlines’ international in November 2015.

All else equal, we estimate that this reduced Brussels bombing in March 2016. (See Chart 1.) European airline revenues in 2016 by around Given that European airlines’ international traffic US$2.5 billion. accounts for around 24% of industry-wide RPKs, this It is difficult to judge what impact this had at a global impact was felt at a global level too: the SA upward trend level because at least some travel would have been in industry-wide RPKs moderated during H1 2016. displaced. But in the absence of the disruption caused by Chart 1 – European airlines ‘lost’ around 1.6% of int’l terrorist attacks, industry-wide RPK growth may have RPKs in the year following the Paris attacks been up to 0.4 percentage points faster than the 7.4% Int'l RPKs flown by European airlines (billion per month, seasonally adjusted) pace registered in 2016. 150 Providing some longer-term context 140 Actual Trend (early 2009-pre-Paris) Nonetheless, as was the case during the SARS 130 Brussels pandemic in 2003 and the Icelandic ashcloud in 2010, 120 airport the impact on European international passenger traffic Paris attacks bombing (Nov 2015) (Mar 2016) has been temporary.
