This offer is back on the Swiss website, for departures from United Kingdom.

For example, Singapore/Hong Kong/Bangkok for GBP199 each way. Book by end of August, for travel from 28th October to 31st March. Not available over Christmas, but otherwise the availability is pretty good from what I have seen.

The downside is you can be put on any LH group flight, whereas when travelling as a couple I would much prefer to select flights with 2x4x2 seating, and opposed to 3x4x3 (or 3x3x3). However for one way travel it's an absolute bargain!
