I have been travelling to ADB (Izmir) on a regular basis the last year, and used the CIP lounge there as late as in November. Now I find that this lounge is no longer listed on LH's site (nor at M&M). Does this mean that LH has terminated the contract? Is there any way to find out apart from showing up at the airport and seeing for myself next week?

It was admittedly a sub-standard lounge, especially the last months when they didn't even repair the fridge so that the beer and sodas were warm, but it was better than nothing.
