Did you follow up with Delta as to why no extra MQMs? According to the Lounge Attendant, my new fare basis was in K, which according to Delta's charts, is 150% MQM. I'm still waiting for my trip to post.
Well, I think DL was supposed to charge me 199GBP (vice USD); I figured I was not going to dicker over the MQMs if I'd paid far less. It was only a week or so after VS started flying the flight and DL agents helping with ticketing.
