Welcome on board, Kiki!
This is great news - the EY 77Ws have a considerably higher capacity (416, vs. approx. 270 on the A332s), so that's quite a lift.
The 77Ws will only operate on the morning flight, i.e. arriving at c.6.40 and departing at 9am. The afternoon flight will still be A332 operated, now 4 weekly.
