We have had very good experiences of true BA lounges when we have had admission linked to passenger status. This time we paid extra for admission to a BA lounge when traveling traveller plus. it is nowhere near the standard of a true BA lounge -or even the lounges of other airlines when we have paid extra for admission. True, it is quiet compared with other waiting areas but it was still crowded. There are no toilets. One has to leave the lounge and re-enter. The food was reasonable but there was little variety. It was very expensive in relation to the admission charge. We wouldn't want to go there again..
