Argh, this is after we booked Xmas 2019- or we'd have considered this for this year. And too early to book my next "return" which would be to LAS for after April 2020... Lets hope for decent prices then, as I could easily go for Upper to anywhere west-coast at £1500pp.
Still, we managed to (in case others want to try same) snag ARN -> BKK for 3 weeks over xmas on Qatar, in J on the new A350 planes for the second leg (with the 777 for leg 1), for ~ £1500pp (how I wished VS flew here, given BA put the bad planes on this route direct, so I was "avoiding" direct routings)... Now just need to get to Stockholm - at moment however pricing on BA to ARN is ridiculous for Christmas, so may end up using £35 avois tickets.
However, we have booked (on hilton points I'd add) the Koh Samui Conrad for the Christmas period. Cash price ... £800 a night, 350k on points. Not that we'd pay the cash price, but easily best "value" of any points we've received.
