Aer Lingus did say would run until end of summer on 6 routes. But nothing has been put on sale from 18th July. Also was mentioned that Cardiff and East Midlands is cancelled until 27th June, so may be possible that EDI, BHX, CWL and EMA will move to BA Cityflyer, and Aer Lingus will still operate flights to MAN.
I see that Esken is looking for someone to sublease their 8 ATRs until April 2023 not sure if Emerald or BA Cityflyer would be interested in this
