[QUOTE - Assuming that the airport one frequents most would have a lounge ,what would one get for 10 USD?
+ A glass of water at the bar, but out of courtesy, one would tip a minimum of 1 USD for a glass of tap water with ice! OK, one would order several glasses of wine or beer, right?

Using your economic formula, it is WELL worth it for me. I prefer to arrive early rather than rush at the airport. This translates into a few drinks ($11 for a large draft at Jet Rocks/PHL), vs. $1-2 at the Club. No brainer not even mentioning the comfort issue....[plus 5K PQM which is roughly a trans-con]......JMHO
