Mentioned in the JER-LHR thread that apparently BA have stopped paying for the lounge there?
This used to be a proper Terraces lounge but has since been refurbished. However it is still unmistakeably BA branded and the staff wear the uniform (the handling agent who operate the lounge deal almost exclusively with BA in JER).
I hope just a temporary thing to see them through the dark times... But I'll not hold my breath.
