Unless ‘O’ is fully sold out, you can only select Lite/Basic/Flex in the ‘O’ bucket.

Lite/Basic/Flex work similarly to Finnair’s concepts: they are fare options offered under most of the fare booking codes.

Once ‘O’ sells out, they will then offer ‘Q’(I think?) until that sells out, then ‘N’, ‘S’ and so on, regardless of the Lite/Basic/Flex option selected.

To book outside of ‘O’ (unless ‘O’ sells out), you need a travel agent or a MH telephone agent.
