[05/25/2019 @ 5:39 PM] Fare gone. Expired.
United and ANA have round-trip flights from Houston (IAH) to Bangkok (BKK) for $555-$565 with a connection. August to October. No Weekends. Departures on Monday, Tuesday, Wednesday, and Thursday.
Note: Fare allows for a stopover in Japan for +$120 more. If you’re wanting to spend a few days (or weeks) in Japan before going to Bangkok, consider doing IAH-NRT-s-BKK-IAH. Example screenshot in the full blog post.
Note: ANA tends to have better service and cabins than UA.
