So let me see if I understand this correctly: Some carriers are charging you thousands $$ for a business lite product that does not include the lounge, but at the same time are selling lounge access to economy passengers and to anyone who wants to purchase one? And this is logical how?
This reminds me of BA charging you thousands for a J ticket and still demands that you pay for seat selection. I for one wouldn't be doing it...
I guess if you can do it and people are still willing to pay - good for the airline.
