Not sure where to post this, maybe a mod can move/delete as necessary.
This may be relevant to those who use ITA to price out mileage runs.
A friend of my was looking for a LAX->TPE RT flight. I recommended that he price it out on ITA, which came out to $1017 on UA (layover in NRT). The new United search did not list ANA flights, but if I search a multi city with stop in NRT I can select code share on NRT for LAX to NRT, but still UA for NRT to TPE. The price is the same.
However, on Google Flights it listed $1004 on NH (layer in NRT). This same set of flights on ITA was at $1108 or so on NH (layover in NRT).
I then checked ANA's website and the lowest fare was $1182!! ... I thought. We couldn't find the $1004 fare at first but eventually found it on Expedia - now priced and confirmed at $1003.xx booked in K from LAX to NRT and S from NRT to TPE. On ANA the lowest fare is all in L.
The key is I don't see this fare on ITA, but nor do I really know how to use it. If I a search with routing limited to K from LAX to NRT and S from NRT to TPE it may show up.
