The crew and the food were excellent. The plane was kept quite clean.

Crew were not engaging. Only engaged if requested. Food taste was mediocre

I booked wheel chair for my mother but she was told to walk by herself in the middle of her way to the gate. She had to board a connecting flight under a time crunch and this was unfair to leave her to walk. Other than that they had no complains about anything else.

More tasty food particularly ethnic food. Staff didn’t respond to calls some of the time in premium economy.

My seat had many issues. First the chair was broken where reclining was difficult. My usb plug was also broken so charging was impossible.

The flight from Hong Kong to Hyderabad didn’t have any power points to charge my mobile. Given we are no longer allowed to use power banks, giving customers the ability to charge even on short flights is critical part of the overall experience.

The experience was very good. A little disappointed for the delays and the screen. The touch screen was annoying for being so irresponsive. Not a lot of good movie choices for me. The service is great. Food could have more choices though.

the crew was rude - there were no smiles when serving. they always had the look of why did you call me?

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.
