It comes just weeks after an Easy Jet plane due to land in Bristol had to be diverted after smoke was reported in the cockpit.
Flight EZY6238, from Berlin to Bristol, had to land at Amsterdam Schiphol Airport after the incident.

Passenger Ellen Braksator wrote on Twitter: “We”re all okay, there was a strong smell of smoke on flightdeck and emergency landed in Schiphol.
