I think all BA A321 mid haul routes are being hit at the moment with substitutions to A321neos. On my flight back from DME last week, the CC commented on a TLV being operated by a neo and no ability to serve a hot meal in Y. A few BA237/236 rotations have also been absent from the timetable with a few BA233/232 & BA235/234 rotations being operated by A321neos of late.
According to the BA source, MEDF went into Madrid Mx on 31/01/2020 and doesn’t look as if it’s back in service yet.
It’s been mentioned before on here but the mid haul fleet is very stretched. It would have been a good opportunity to replace the old fleet mid hauls with A321neo aircraft (except with proper galley and toilets at the back).
