and just to give an update on the situation for economy class passengers i encountered the following:
Booked HAM-DXB-ADD-DXB-HAM (the flight has a 9 hour layover in DXB) - upon requesting the stpc I was told that since this ticket was booked in V (how would I know) this ticket would not be valid for accomodation.
They said that only B?? and true Y class tickets would be honored with a free hotel in Dubai, however if i upgraded using miles I would get the full business class deal with hotel and limo.
Btw was told that the fare difference between V and B??? was only 200 EUR.
