On a long east–west route like this one the two directions do not take the same time. Aircraft flying eastbound ride the mid-latitude jet stream and typically arrive earlier than the westbound leg, which flies into it. The difference is commonly 30 to 90 minutes on transatlantic and transpacific flights, and it varies by season. The estimate above does not model wind — treat it as a midpoint and check the airline's own timetable for the block time on your date.
