Greetings all. I'd appreciate some informed clarification. I've had a non-trivial amount of miles in my Executive Club account but haven't had occasion to fly BA in a couple of years. After a recent Hilton hotel stay, I successfully credited some miles last week to my Executive Club account. The BA website, however, still reflects the same original dates for "Membership Year ends:" and "Card Expiry Date" that were listed prior to my newly-posted miles from Hilton.

Are my EC miles still at risk to expire in February despite my recent hotel-partner activity? Or is mileage expiry a separate matter from "Card Expiry"? Should I just wait a bit longer for the online systems to sort themselves out and reflect an updated expiry date?

Many thanks in advance for your insights. Have a great holiday season.

EDIT: NB - Alas, I'm now longer EC Silver, as my profile suggests. Barely clinging to Blue.
