Thats interesting I didn't know it was only a benefit of being a DM member... oh well at least passengers in F know how to tell the difference between who's actually paying to be in the lounge and who's there as a benefit - while they're walking to the plane they'll see us DM's in our buggy's.,.. hehe...
If you're buying F tickets I don't think you should be cribbing about the HK$40 (US$5) buggy...
