I'm not too sure because I've never used my miles with a Q miles partner. You will have to pay the taxes and charges before the ticket is confirmed so someone should contact you beforehand. Personally I would not bother using your Qmiles on a European short haul flight from the UK- the taxes are so high (especially with BMI) that it is unlikely to save you much money, especially if you get a good Easyjet or Ryanair flight in advance.
Save them for an upgrade or a long haul flight in the future
