Britain and the European Union joined China, Malaysia, Singapore, Australia and other countries in banning the 737 MAX planes, piling pressure on one of the Dow Jones Industrial Average's best performing stocks this year. Air Canada cancelled multiple scheduled flights to London after the U.K. closed its airspace to Boeing 737 Max 8s on Thursday. Boeing shares fell 6.1 per cent to $375.41 US on Tuesday, adding to a five per cent decline on Monday. Boeing shares have delivered a total return — including reinvested dividends — of nearly four times the performance of the full index since U.S. stocks began rebounding from the 2007-09 financial crisis. Boeing defended its aircraft and said it has "full confidence in the safety of the Max."
