Thank you all, that's good news! I'd read the following on LATAM's website https://www.latamairlines.com/gb/en/...irport-lounges Signature Lounge

Access this lounge if you are a Black or Black Signature LATAM Pass program member, or if you are traveling in LATAM Premium Business* cabin.

You can also access this lounge if you are a Diamond or Platinum Delta Air Lines loyalty program member, or if you are traveling in the Delta One* cabin.

Premium Lounge

Access this lounge if you are a Platinum LATAM Pass program member, or if you are traveling in LATAM Premium Economy cabin.

You can also access this lounge if you are a Gold Delta loyalty program member**, or an Emerald or Sapphire Qantas, Japan Airlines, and Iberia member when traveling with LATAM.

WorldMember Lounge

Access this lounge if you are a WorldMember or WorldMember Limited Santander customer when traveling with LATAM.

*Customers must present their boarding pass or a flight confirmation for Premium Business or Delta One cabin on an international flight operated by LATAM or Delta on the day they access the lounge.

**Customers must present a valid proof of Gold category in the SkyMiles program and a boarding pass or a flight confirmation for an international flight operated by LATAM or Delta on the day they access the lounge.

So thought we wouldn't have access to their lounges. The reviews of the Pacific something looked pretty dire and not worth the bother. So I'm very happy to hear we can access one or other of the LATAM lounges.
