The BCN has operated at that time as you say but has been a turnround - last time I travelled on it (2015) from an inbound Bordeaux. But it does look like a first timer- something still to be slotted in? Can't see anything clever going on like the Belfast which seems to turnround to Malaga.
I've noticed Easy prefer to do multiple airport sectors rather than W pattern - earlier this year travelled on a flight which was part of
LTN-JER-GLA-LTN-ABZ-LTN
The crew weren't that keen on 5 sectors!
