When selecting most Business International fares using Fares/DOT RES (both IT & UK as US does not work anymore) only coach fares display. If you select First, First will display. Try NRT- JFK, or BOS-NRT or TPE- LAX, or LHR-BOS (AA, BA or CX or ALL). They all display Coach only when selecting Business.
And Fares/TVN remains semi useless if trying to display Business and First (and all coach) if the list is too long.
