It was good delayed again but once on board the flight crew were very good the entertainment and wifi worked on this plane and we were offered snacks and drinks

The second half of terminal C at Hartsfield was 80 something degrees. I was sweating just sitting at the gate.

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

Friendly flight attendant Quick checking for baggage drop Quick TSA lines

It was okay. We were delayed for weather reasons, but the pilots and the flight control staff figured a way around the storm and were able to get us to Los Angeles safely. Not all the staff members were polite, but the entertainment on the flight was good.

So terrible. My flight was 4 hours delayed and we weren't notified til last second within an hour of boarding. WE had to sit on the plane for 4 hours. ridiculous.

Missed the Flight from Atlanta to Roanoke due to initial flight from Houston being 2hr. late. Now waiting 17hrs. till my first available flight.

Internet didn’t work for this leg either. The seat was fine but didn’t have seatback screen, which I knew when I booked it. The biggest letdown is Deltas new policy on beverage/snack service not being served for flights less than 350 miles. I know this is a cost cutting measure, but how much does it really cost to give a drink and a snack for inflated airfare? I really am surprised that with Delta Comfort they don’t provide beverage/snack service given these seats cost extra to purchase. Really need to reconsider this, even if it’s for the Delta Comfort and above.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

PREMIUM ECONOMY - excellent !Brilliant new plane. Excellent tv catalogue. Good food. Good communication and service from all friend Australian crew. Good communication from captain. Best travel experience in years.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

Loved the staff. The economy seats could have been bigger.

The food was terrible. And the flight attendants were very rude. One flight attendant wouldn’t help a passenger lift their carry-on. Another flight attendant wouldn’t give a man an extra blanket. And they walked by not even looking at the passengers to see if they needed a glass of water.

Delayed and missed connection, was not re-booked like other travelers so ended up being stuck for several hours due to no one handling my booking.

same as previous comments. i hate being on a plane that long. no problems w/anything else.

Much better than I expected for such a long flight.

Good - better than other airlines in terms of food and seat comfort.

Experience was great. My only advice is to have a pasta dish on the menu. Otherwise everything was excellent.

Flight LA to Sydney was first moved earlier by 2 hrs from 10:25 pm to 8:25pm roughly a week before departure. Then on actual departure date, it was delayed 2x, and needed up leaving close to 10 pm. Then entertainment for the whole flight wasn’t working for most of the seats including ours. The baby crib at the middle isle was being taped to the wall to keep it tacked in using a packing tape while passengers were walking by looking for their seats. Not projecting good confidence. After a few minutes after take off the whole crib fell off. Good the people seating next to it wast hit or got scared. At arrival at Sydney, crew handed the customs forms as we were getting out of the plane. So passengers had to scramble to find a place to fill up the forms along the corridor going to immigration. So no one is available to help from Qantas to fill up the entry forms. Not a very good experience for a flagship carrier.
