Schedules change, so the search shows the airlines and connections available for your dates.
Nonstop or one stop
The nonstop flight saves hours but tends to cost more. A connection in Tokyo, Hong Kong or Seoul can be cheaper and breaks up the journey.
Sleep matters most
On an ultra-long-haul flight, a fully flat bed with direct aisle access makes the biggest difference. Check the seat layout before you book.
Flexibility pays
With few nonstop flights a day, moving your dates by a day or two can change the fare more than switching airlines.
