To better match up with their partners, Delta and Virgin, KLM and Air France move to Terminal 3 at Heathrow today, 24 August 2021.

KLM are showing that eligible members are able to access the No.1 Traveller Lounge (Lounge F) at T3. (Open 0430-2230 daily says KLM but the lounge web site says 0600-2100!)

The Air France web site hasn’t been updated to reflect the move.
