Are we seeing evidence of another stealth change with -UP fares no longer earning the 150% MQM bonus for G A P type fares, but only earning based on the underlying H-UP or whatever fare code? This would be rotten as the underlying fare code isn't displayed when you purchase tickets on delta.dumb; you must click through into the fare rules to see the fare code and often the system responds very slowly or even says that the fare rules can't be found. I don't know how to retrieve this information on delta.dumb after purchase on delta.dumb, although it might be on the receipt if you know that you must look for it.
