I know ya'll are really talking about FBO type of "lounges" but you should see what the DAL pilots have at JFK. It is sooooo incredibly awsome words defy description. We have our own zoo... Occasionally it is in a rain forest environment... If you like spelunking (actually called caving), you can do that there too. If you fly long flights, the humidity level is precisely controlled for your comfort and recovery.
Thank you.. I'll be here all day...
