I rarely travel by air, but since all the airport lounges went smoke free, I have little use for them.
Went I stopped in such lounges, I kept in mind not to drink so much than I would fall asleep and miss my flight, or worse yet, need to rush to the gate and board my plane in that condition. This was pre-TSA. The menus were usually good, albeit overpriced to their captive customers.
I did a three week trip to Australia about six years ago...all business class. The plus-up I thought...would be the airport lounge (Frankfurt, Dubai, Sydney, Melbourne and Brisbane). With the exception of Dubai...the lounge business was a joke....mostly overcrowded, and marginally stocked.
