Anyways it's not a big loss. In these past years, you could already feel the times were hard for Spanair. The lounge in BCN had some crackers and few drinks at best...not even free internet last time I was there. Was almost alone in the lounge, with a couple who had obviously regretted to pay their way in, and a very enthusiastic crew talking loudly.
Plus the terminal from which LH flights take off is modern and very comfortable. So really, nothing to cry about! (moreover as saviox mentioned it seems LH will be providing other partners lounges, which can only be better than the Spanair ones!!!)
