I woke up this morning to a pleasant surprise. An automated email saying we saw you looked at booking X, want to go back and buy? It was sent from the generic
British Airways Executive Club <[email protected]> address. However, at the bottom, with my Avios balance and status, I noticed BA have 'upgraded' me to GL and they had added the branding next to my account.

I looked at the past few emails that they've sent and the the latest edition of the Club email, also listed me as GL. Emails before Feb 6th all just (correctly) show me as gold. Obviously, I logged into my BA account and nothing has changed there (disappointing) although it may change soon (when I actually earn the last few TPs).
So, my question, has anyone else noticed a non-upgrade to GL in emails? Has BA just added this iconography for all Gold customers to reduce design work? Am I just guessing incorrectly that this is the GGL branding? Does BA have a plan to make me GGL for fun (I'm stretching now)?
