Longhaul Lounge
- AY Longhaul J
- Oneworld Emerald and AY Gold (Shouldn't make any difference if on AY or BA - I would raise hell if it does)

Gateway Fresh Lounge
- Shorthaul non-Schengen J/C on pretty much every carrier incl AY
- Oneworld Sapphire and AY Silver

As far as I can tell, both have similar selection of not so premium drinks. Fresh now has food at least in the evening - meatballs, potato salad, yoghurt, breads. It was much better than before.

Schengen (not sure if this is accurate)

AY Golden Gate (very restricted opening times)
- OW Emerald+Sapphire

AY Silver Wings
- OW Sapphire+AY Silver

Gateway Tower Lounge
- Shorthaul J/C with no status on a bunch of airlines, KLM, AF and the likes with status cards

Does anybody know if Silver Wings is accessible as Sapphire on a domestic AY flight?
