If it prices then nothing I've seen suggests you can't trust that *price*. So it's a useful way to get input on likely taxes & surcharges for a given routing. This info likely takes days to get otherwise and is then still awkward to get for multiple similar routings which is what you need to get a sense of what changes hit taxes and surcharges non trivially.

I suspect the ticketing carrier matters on occasion too but there seems no easy way to find info on this. Maybe this recent sharing trend will lead to that. I very much welcome people sharing pricing info so we get a better sense of *ticketed* costs in various situations. Plus it may spark routing ideas. Please don't anyone be discouraged!

It would be nice to have more of it one currency mind, usd seems the obvious one. And yes, I would also strongly encourage people to consider the aa rtw desk to be their default for actual ticketing unless they really know what they are doing. The ease difference is generally enormous.
