It now appears there is now a slight increase in flights and consistency. On Friday (13th march) Etihad realised seven days of planned flights on their website. Previously they had only been giving two or three days worth. The two legs I want to fly are now included in this list. I'm now monitoring these flights for reliability and logging the data.
Daily flights from MAN re-started yesterday (SAT 14th March). This is EY 78 which departs at 05:05 which is over three hours earlier than before the conflict started. The weird thing is that the inbound flight to MAN (EY77) arrives AFTER the outbound flight from MAN. This means there is an Etihad plane parked overnight at MAN. It's probably also the reason EY77/EY78 have used bus gates for passengers so far.
Please see the screenshot of a document I created regarding parked aircraft at MAN:
A= Arrival, D=Departure.
