Not quite as empty as you might think, felt a bit like Dec 26th.

AerClub/Business check in was closed, appeared to be a single desk open at the customer service desk end
Fast track is open
T2 is sufficient to cover all EI mainline departures, no south gates and no 30x
Lounge remains closed as "non essential service", but you still must navigate through the loop which is fully staffed and open. Very confused
Boarding strictly by row number from the back
Usual hassle on arrival with people jumping up to grab bags and making a run for the front of the plane (its last on first off)

Loads
EI330 July 21, 75 checked in, 74 onboard which isn't bad, I've seen a lot worse
