Budget airline easyJet was the biggest laggard, down over 6percent after saying that its annual profit would fall by morethan 25 percent this year, its first drop since 2009. It citeddisruptions, security concerns and an adverse exchange rate.
Shares in rivals IAG and Ryanair both fellmore than 2 percent.
"Despite easyJet's strong margins ... and attractivestrategic positioning, we see negative EPS momentum as thedominant driver for the shares in the short term," analysts atLiberum, who have a "sell" recommendation on the stock, said ina note.
"Given the seasonality of easyJet and the airline industry,we see it as unlikely there will be a positive catalyst muchbefore summer next year."

Unicredit shares rose 2 percent. Both DeutscheBank and Unicredit have roughly halved in value this year.
