But in my case I don't think my flight from DME to KUF is shorter than MUC to DME, although I am sure there are examples of what you suggest being the case. I am still reluctant to throw money, however little (and RUB is not that little), to upgrade to a product that does not offer lounge access or extra miles. Furthermore, I notice that Business Basic fares from MUC via DME to KUF are pricing at RUB40,000 and they come with they caveat of no lounge access, according to the website.
