American Airlines has round-trip flights from Houston (HOU/IAH) to Tokyo (NRT) for $537 with a connection. Flights in November. No Weekends. Departures on Monday, Tuesday, Wednesday, and Thursday.
Note: Upgrades into “Premium Economy” are available for +$402 more. We think this may be worth it if you want to sit in the larger style seats and have an upgraded dining service.
Note: Checked bag and carry-on bag is allowed for free on JAL / American Airlines.
Note: Be sure to check both “IAH” and “HOU” for availability.
