This is why sometimes during irrops, an agent will refuse to put you into confirmed first class. They see the Fare Class and see an Economy letter. They are wrong, of course, but based on reports, it has happened to several people.

I say buy with confidence, but also be ready to HUCA if needed (again, with confidence!)
