Pros: the flight attendant on board was lively in making announcements!
Cons: Flight was first brought forward by 30 mins. Arrived on time at the gate, but actually it's delayed by 15 mins from the original time. So in total delayed about 50 mins from brought forward time. NO ground staff at the gate bothers to inform us. Flight status screen shows "Callng", when approached, ground staff just replied "not yet" in a bad manner. Terrible ground service.
