Delta has round-trip flights from Houston (IAH) to Hong Kong (HKG) for $716-$722 with a connection. Flights August, September, October, and December. No Weekends. Departures on Monday, Tuesday, Wednesday, and Thursday. Origin/Destination reversible. No Christmas dates available.
This will either have a 5-hour or 14-hour outbound overnight connection in LAX. The return leg of the trip is has a 2-hour connection.
I think this is worth it for the 14-hour connection, and booking a airport hotel for the outbound flight at this price.
