Sorry Tobias, I edited my post to add the Wigan kebab comment before I saw that you had mentioned it.
On a more FT note, I got a message from Amex Plat today saying that
As part of your Platinum Card membership you have access to 4 complimentary lounge pre-book entitlements to use in 2025, and another 8 complimentary pre-book entitlements to use per calendar year between 1 January 2026 and 31 December 2027.1
Obviously nothing for T3 but the Manchester T1 & T2 Aspire lounges are in there
