If you live in Europe, I believe you fall into the SPP program. Self Pre Positioning or something like that.
That means they will pay for an equivalent cost of a ticket from STN to the initial start of your pattern since there is no flying out of STN and all interim travel on that pattern. If that is STN to FRA as a DH, your going to get the cost equivalence of what a Ryan Air or any other budget carrier to FRA from STN. That is what the charge is before the weight and other add ons that they do. If you live in Europe, it is a little tough to start a trip in another part of Europe under that. If your pattern starts in someplace outside of Europe, like DXB, then your doing OK with a business class ticket there or DH on company A/C.
