I must repeat my question as of before..
Is it true or false that BA no longer follow the two cockpit policy?
You can repeat your question as often as you want but no professional aviator with any sense will give you answers to questions involving security measures - being blunt there is a principle called "need to know" and in this case you don't "need to know".
If you insist on conflating this with the elderly pax: severe credibility probs with the media reports, done to death elsewhere on Pprune.
