[08/10/2019 @ 01:08 PM CT] Fare gone.
United has round-trip flights from Dallas (DFW) to Singapore (SIN) for $578 with a connection. Flights August, September, October, November, and January. No Saturday departures.
Note: Fare allows for a stopover in Japan for about +$130 more. If you’re wanting to visit both counties on the same ticket, you’ll want to do something like DFW-HND-(stop)-SIN-DFW. Example screenshot in the full blog post.
