How long prior to departure does ET typically sort out equipment swaps? My flights FCO-ADD and ADD-LFW-JFK both currently show 2-2-2 configurations however flightradar seems to indicate that 713 has been operated by 1-2-1 reverse herringbone configurations quite a lot lately. I have currently selected an aisle in the middle section but would obviously much prefer a window in the 1-2-1 config.

Also does anyone have very recent experience transiting in ADD? Just wondering if there is good info about covid testing requirements as there is lots of mixed info online, none of it particularly recent
