Seems something might be wonky with CI's A350's or the pilots are having issues with ONT's windy conditions since CI again cancelled its night flight out of safety to today @3:50p. The aircraft that was going to be used last night was B-18909. Seems they're going to be using today's TPE arrival B-18902 for the return flight to TPE. Tonight's flight is still on @10:50p with B-18909.
