BKK-DOH J to F in 2 weeks again pricing as THB 45,579 (c.USD 1,320). No absurdly high avios option available currently though (133,000 a couple of weeks ago).

Incidentally, the THB 45k is more than the fare difference J to F for a one way on that flight currently, and also doesn't include the extra luggage, qpoints, avios and AS access (if you needed it) that reticketing in F at the lower price would. It's hard to fathom the logic....
