I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

great experience, excelent aircraft, crew, services onboard a dream come true

The check in women was very nasty attitude to the passengers from Lihue airport flight 68

First time in a long time and look forward to many more

We are a family of three, bought two economic tickets for me and my teenager daughter, a business ticket for my elderly mum who doesn’t speak much ENGLISH. During the flight my teenager walked up the plane wanting to chat with her grandma, stayed a bit and my mum consequently wanted to exercise so she walked down to our cabin too. My mum sat with me and chatted for about fifteen minutes then i went to business to check on my daughter only to find out she was not there. I was met with this extremely rude Hawaii Air flight attendant, after i told her my daughter is missing she couldn’t care less, she told me we can’t swap seats and insisted that i immediately return to the economy cabin. But then my daughter was still no where to be found! i explained and hoped that they could at least suggest some way to find her such as announcement or something, but the following words came out of her filthy mouth: “ Go back to your seat immediately! this is the last warning!” WTF?! i can’t believe this is the way Hawaii airline is treating their passengers and we paid business class fees! Very insufficient and incapable flight services as well by the whole crew. Overall extremely unpleasant flight experience! i will definitely spread words about this to ALL my family and friends and colleagues you name it. Never fly Hawaii Air ever again! Never!

Allowing passengers to move to empty seats if flight isn't full.

Enjoyed every stage of travel and really loved the free WiFi on the international flight. I would only make one recommendation. There was a lot of young children under 2 on the flight. Loud crying screaming and just playing. Constant poopie diapers. These families were spread through out the plane. Some of the passengers with no patience actually yelled at these parents unfortunately. I would recommend keeping all the families with young children in the same part of the plane if possible that way the passengers that complain can be relocated. In this situation there was no part of the plane that didn't have a noisy child. Any ways I will be flying Hawaiian airlines again because the service was just that good!

It was a 48 min flt......so no real comments can. E made

The food wasn’t very good but everyone on the plane was great.

Friendly crew, flight left on time and arrived early. Had problems with using in flight entertainment on my iPhone, could not get it to work, with WiFi available. Liked being able to charge my phone. Overall a good experience!

The plane was nearly empty. My wife and I were seated behind a family with 3 sreaming kids. The parents refused to control their kids. When we tried to move to a quieter section of the near-empty plane, the flight attendant said please return to your seat. When we tried to explain, he stared at us coldly and simply repeated please return to your seat. When I asked if we could move after take-off he simply start and repeated please return to your seats. About as far from friendly and helpful as you can imagine.

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

It was very nice. I will try to fly with Qantas whenever I can.

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

Much better than I expected for such a long flight.

Flight was cancelled about 1.5 hours before departure. Replacement flight provided scheduled 1 hour later. Late boarding, late departure and arrived Melbourne nearly 2 hours after originally scheduled.

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

It’s a very long flight and there are so many people on board. Perhaps a warm washcloth now and then to freshen up

The crew was very helpful to my family, especially when my daughter became sick during the flight. Will fly with them again.

Too many passengers are bringing on too many large items as part of carry on baggage where it should be checked in. This is not the fault of Qantas but the stupid mindset passengers have now about trying to bring anything and everything on as carry on luggage where it should be checked in.

Better than expected, normally I don't use this airline because they are too expensive for me, but if you can afford it, good on you, you won't regret it. Regards.

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Had a crying baby and a toddler behind me so it was difficult to get comfortable. Searing was tight even for a relatively small person like myself (5’8” 155). Fast flight but arrived so early the gate assigned was still occupied by another plane so we had to wait for about 20-25 minutes to get reassigned to a new gate and get over there.

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

Seats are smaller and harder than other airlines we have travels with. Food was edible but no good. The sandwich was the only thing I would eat again. They did have a lot of movies to watch.

boarding was uneventful. Snack was pathetic. A tiny fruit bar. Entertainment was limited to just select movies on your own tablet or phone. No live TV. I recently flew Jetblue and they had unlimited snacks and live satellite TV the entire flight. My seat was an exit seat, 20A. It was super uncomfortable. It felt cramped and the middle seat was taken up by a large woman who pushed into my shoulder and arm. Horrible flight.

I liked that the flight to Kosice was on time, the service was excellent and we arrived to Vienna early. The only thing I did not like, is that I had to pay for my suitcase $75. Bummer

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

This flight was a lot more comfortable with more room than the Air Canada Rouge!!! We will never go rouge again! A yes to this one!!! It was so nice to have inflight entertainment! Also the carts came around twice for drinks or a snack!! Great experience all around!

AC flight attendants aren't overly friendly. Otherwise flight was fine.

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

I’m handicapped and the staff and crew were so kind and helped me board and made sure I was fine during the flight.
