Club Aspire Lounge – Gatwick South

Club Aspire is a quieter PP alternative to No1, but closes around 1pm. Morning departures only. Solid food, staffed bar, views of the BA apron.
BA Club Lounge – Gatwick South
A bright, well-designed business lounge that outperforms its Heathrow equivalent on light and calm. Reliable buffet, full bar, Kids Zone. Sapphire and J class.
BA First Lounge — Gatwick South
The best lounge at Gatwick South for status holders. Quieter than the Club next door, good natural light, and a solid airline buffet. Gold and Emerald only.
American Airlines Admirals Club Lounge — T3, Heathrow

Functional and dated, but early-opening and reliably clean. The weakest oneworld lounge at T3 — use the Cathay or Qantas lounges instead if your status allows.
ANA Lounge T2, Heathrow

No dedicated ANA lounge. Business passengers and Star Alliance Gold use the SilverKris Business Lounge (preferred) or United Club depending on opening hours.
Air Canada Maple Leaf Lounge T2, Heathrow

Star Alliance Gold on AC flights. Buffet, staffed bar, complimentary showers. Consistently outperforms expectations; Canadian whisky bar is a differentiator.
