Hi
MarkUK. Welcome to FT ^
Even though your question is o/t on this thread, as it is a specific question rather than a pooling of info on upgrading on *A, I'll go ahead and answer it.

The latter.
If I don't manage to get an upgrade to business (none available) I assume I will be better off on UA in econ+ than on LH in regular economy?
Yes.
I'd suggest that in the future, you start a thread when you have a specific question not totally related to that of the thread
. Again, welcome to FT.
