In 2014, British Airways replaced three 777 flights between London and Los Angeles with two A380 per day. Emirates' Tim Clark saw a large potential for Asian A380-users, and criticised Airbus' marketing efforts. As many business travellers prefer more choices offered by greater flight frequency achieved by flying any given route multiple times on smaller aircraft, rather than fewer flights on larger planes, United Airlines observed the A380 "just doesn't really work for us".--> It employs Boeing 787s operating at a lower trip cost.
