Great airline service by the staff. I highly recommend it

Needed more leg room. Leg rest and entertainment system box took up a lot of space and I'm not tall. Breakfast was good. Poor quality of the entertainment options.

Time to upgrade those planes so you can provide first class.

Aircon set too high so VERY warm and VERY uncomfortable.

Great! Flight was delayed by 30 mins but all was great. Thanks.

Arriving at Coolangatta, rows 20 forward, took the airbridge across to the terminal. It was suggested to those from rows 21 back, that we take the rear stairs and to be careful crossing the tarmac. That was all well and good. However, when we got across to the terminal we then had to climb three large flights of stairs to meet up with those coming across the airbridge. No elevator! There were people carrying babies and elderly carrying hand luggage that needed assistance from others.. There was no option to turn back.

Flew premium economy, well worth the extra. Much better seat size & space. Meals & snacks were lovely. Crew really pleasant. Internet is not great, not really useful for anything. Couldn't even send messages.

Overall, a great experience from food and crew. The only setback was that this was the Second flight from Air New Zealand within a week that was an hour late for boarding.

The air New Zealand employees who assisted us with wheelchair aid on Auckland made our transfer from flight to the next seamless. Also were amazing in helping with our luggage and customs in Brisbane.

All was good, the only thing was it didn't run on time.

The gentleman at the gate I think his name is RIE was exceptional

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

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

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

It wasn't really their fault it was the horrible winds and we just got unlucky.

I wouldn't say I liked being forced to check my small roller bag at the gate; too many people had bags and were in a higher boarding group.

715PM departure was 2.5 hours late. Received hotel & food voucher but after we already booked a room. Entire team just seemed like they were 2-3 steps behind in execution, and notifcations.

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

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.

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

One of the best Qantas business flights I've had. Quality product

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.

I have flown Qantas multiple times in the past it seemed this flight the plane had less seat room or the seats were way less comfortable than before. Everything else was about the same. Thanks

I disliked the fact that they forced people to put up their seats during meal service

Enjoyed the new possibilities of in flight entertainment. Been awhile since I've flown, and that was a nice surprise. Being able to pick from such a variety was personalized and welcomed.

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

The small flights with Valet Luggage has a poor service

Overall a good experience, however Wifi was not working on the flight.

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Human interaction. Thought there would be more service-even a smile would have been nice.

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

Delays with no explanation. It could have been handled better.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.
