I was pretty early for my flight so had a pleasurable hour in this lounge at Tegel. Located on the mezzanine level it at the opposite end of the main terminal from the BA lounge. As the A gates at TXL are located in a horseshoe shape, they are accessible from both lounges.
Access was granted on the basis of my United 1K card which gives Star Alliance Gold status. There were only a few passengers there when I arrived.
There are a large number of different seating areas in the lounge.
There is a wide selection of cold food items and breakfast included a fridge with yoghurt in around the corner from the main food options. Rolls, meat, cheese, yoghurt, fruit, cereals etc.
A selection of self-service hot and cold drinks were also available.
The departure board is visible from parts of the lounge so you can keep your eye on when you flight is going.
A perfectly good lounge with plenty of seating and the standard selection of LH snacks.
