Well, in my case if I wasn't enjoying lounge privileges when I gotten my SL, I would probably stayed with AA and fly their metal. I don't know, 10 flights a year at average of $2000 per ticket for the last 6 years, that's $120,000 USD more CX made from me because of SL lounge benefit. And I'm sure I'm not alone in this. Say 1000 people had the same experiences I had, that's $120 million.

Taking away lounge benefit for SL would be a big mistake in my opinion.
