I don't know why UA just doesn't give up on this pretense of having first class service and just sell all premium international cabins as business and be done with it. For flights with the old F suites, just hold them back for sale or a few hundred dollars unless full fare C or GS. The catering is almost identical and they can save on the soup and few extra starters. The wine and booze haven't been anything to write home about for many years, and now they are being shared between the cabins, so why bother?
