I do think some of the Dreamliners will go to OS, but probably not 10.
LH has been a bit difficult about even giving Austrian anything, but since OS long fleet is in need of renewal I see them only giving them 6-8 Dreamliners to replace the entire long haul fleet even if it means cutting down routes or frequencies.

...now CA. 🙈

Details of the split are coming out... it looks like OS, LX and LH will get some B789 love:

Omg as someone living in Vienna and preferring OS service over LH, this is great!

what are the chances of a nicer new business class in OS yet still keeping a 1-2-1 layout and not 2-2-2 like LH has�?

They should be getting the new C, but then OS would be ahead of the mothership who are taking the Hainan white tails with that specific c seat. Why not, if LX is getting the new W seat first?

Doubt that they will keep the Norwegian seats.

For now it's just a rumour, although the four planes for OS would makes sense to replace the 767s. I imagine 6 of the later 789 deliveries will then replace the 777s, which would make the split complete. (10 OS & 15 LH)

I'm still convinced and hoping LX will get A350s.
Would be quite surprising if LX got 789s with a different layout (with F) anf go against LH oh so holy synergies and standardisation program :P
They will get the new cabin and seats, which should be 1-2-1 or similar, but with LH new Business you never really know... Could be 1-2-1 and 1-1-1 staggered so much it might feel like a 2-3-2... I'm not sure if they will get the new LH C cabin or if LH will just install their temporary new C they will get on their first five 789s and just use that on all 789s...

The Hainan one don't have a cabin installed afaik and should get a LH specific seat/interiors, including a new C seat. Hoping for a Thompson Vantage XL myself :P

Some new info seems to be available to EAF which suggests LH will take up to 21(?) B789s, 9 of which are white tails to be delivered in 2021 and 2022 using the semi-new Business Class.
B789s from 2023 will then get the new Business Class.
This would somewhat fit in with my theory that the 789s will be split between LH and OS as LH can replace their aging 343s and 333s in FRA with them and OS will get them to replace their remaining 767s.

I can see OS going all B787 very quickly and also the B772's disapearing within next 2 years or so.

For LX's future I am optimistic that they will receive as of 2025 A359's to replace the 5 A343's followed by WK replacing their A343's as well. Shoud LX require grow it's long haul fleet again following the withdrawal of 5 A333's I can see them receiving up to 5 more between 2026 -2029 after which they will start to replace their remaining 9 A333's. Who knows as of 2035 we will see A35X to replace the B77W's at LX

I think it might even be an option that LX A333s will be replaced earlier and moved to either LH, SN or *shiver* 4Y.
I too would see the A35X as an option for LX, more so before the pandemic than now. It would fit Lx's 8F layout and feature enough space to accommodate a healthy growth as well as the new Y+ without cannibalising C or Y in comparison to the A343s and A333s.

Ultimately I believe we might end up with a mix of A359s and A35X or even the rumoured A350-950 for Qantas project sunrise.
ZRH-SYD/AKL? One can dream...

I am hoping LH will keep the 346s around a bit longer ... else LH F will become completely elusive
