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.
