Apologies to rehash the question, but am currently scheduled to depart from T3 (per the BA website) to AUS in July. The flight currently departs from T5 so am wondering if the T3 listing on the website is indicative that they make the switch back to T3 in due course?

I assume I am in the minority, but I actually prefer T3 departures for the excellent lounges.

Thank you for any prognostications!
