This is on the same, upper level, that you enter once through security. Turn right out of security and it is near the escalators.
I showed my gold status card and my boarding card. My business class ticket with Thai airways allowed me entrance to the business lounge and the status card to the Senator lounge. From reception you first enter the business lounge.
This was much lighter and bigger the the Plaza lounge. Again more crowded than I have encountered on previous visits but there were still places to sit and relax.
At the end of the business lounge is a door opened by waving a piece of paper with a QR code under a reader. You can then enter the Senator Lounge.
As before this seemed more crowded than the business section. As far as I understand it this lounge is for first class ticket holders and premium status holders. Although I am one of the latter I wonder how I would feel if I were a first class ticket holder. Perhaps Lufthansa needs to reconsider their admission policy.
The Senator lounge is smaller in area and feels as if it has more seats per unit area than the business area. There is certainly less free circulation space.
The food selection was similar although a little more extensive than Plaza. Again there were a couple of hot selections and cold foods. The beverages were serve yourself in both areas with any of the soft drinks and mixers, Coke, soda water or tonic water etc provided via a dispenser rather than cans. I presume this reduces waste.
The food and drink selection seemed very similar in both areas so again I can see no benefits of the Senator Lounge over the Business Lounge.
The toilets were clean and modern and had a pleasant air freshener smell.
As my departure time approached I made my way to the satellite part of terminal 2.
