Nah, all this is adding up to the fact that ANA is simply displaying availability to ANA members (ie Japan based), whereas *A carriers are releasing availability on a originating market basis - this leads to inconsistencies.
And they're getting more noticeable by the day as they seem to be doing things differently, increasingly.
A year ago, what you saw was what you got, they SQ went funny, then married segments became a bigger issue, Scandinavia went for a walk, then LH connecting flights couldn't be bagged and tagged... anyway, it'll all be irrelevant soon enough, as we'll all be using an LH tool.
I have my suspicions that we're already being treated to that via the ICC.
