The three affected routes are Dallas to Beijing, Chicago to Beijing and Dallas to Hong Kong. All three flights, which typically fly over Russia, will be sent through Los Angeles instead, and the measure is expected to cause delays.

US President Donald Trump on Friday announced a US-led series of airstrikes against Syria, which Russian President Vladimir Putin described as an "act of aggression." The strikes were carried out by US, United Kingdom and French forces in response to Syria's latest chemical weapons attack, which killed many civilians.
