bmi diamond club - BA T3 Flounge Access with BD Gold Card

Travelling to LCA during the first week of June, and BA flies this route from T3.

Will my BD Gold Card get me into the Flounge? I've dropped from BA Gold to silver, so as a fallback I can get into the Club lounge.

If it get's you into GF at T5 no reason why it shouldn't at T3.

Assuming you are on BA to LCA should be no problem. Will you be status matching your BD G to upgrade your BA S?

A BMI gold card got me into the T3 F lounge when I was still BA silver.
