The is a case of economy fares that will automatically get assigned to the next higher cabin (such as domestic F) when purchased (and the fare ules are met and a particular F fare inventory is available). They are call -UP fares and can be associated with any economy fare class, such as Y-UP, V-UP or W-UP, or .... These are not Instant Upgrade YBM fares and the -UP fares come in two forms (traditional & UPDI)
