Just flew from JFK to HKG can compare with the same flight I took in March.

- No welcome or thank you for being an Asiana Diamond. Had this in March and was proactively offered a bottle of water upon boarding.

- Meal service seemed a bit disjointed. Tray was served but the drink trolley wasn't together - if I remember correctly they used to serve the meal tray and drinks from the same trolley. Drink wasn't served until 10 mins after receiving the tray.

- Also found the crew less 'smiley' than before. Just my own perception.

- Still though I would say the overall service was high with frequent water runs throughout the flight and the quality of food was consistent.

I'm flying back to JFK again in July and will get to compare then.
