This is a typical misinterpretion:
Customer says: Lounges are overcrowded - wants expansions of the lounges.
Mangement does: Throws some people out of the lounge, losing many customers.
What may come next:
If LH thinks that the C-Lounges are now less crowded (which i doubt, see my previous post). Than all *G members will get the allowence to visit only the C-Lounges...
The next step is that FTLs traveling only can use the Lounge when traveling on Full-Fare Y Tickets! (Like BMI!).
Then they could restrict the Lounge-Acces only when your last digit of your ticket number is odd....
What cost can you generate in an FTL-Lounge? You only get Softdrinks, Beer and Coffee. No expensive stuff!
Sorry LH.
