Not very comfortable seated in the back plane due to turbulence

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

Ford not that great the seat not to big for leg room like other airline

On time and flight crew are always so happy to help and always smiling unlike other airlines.

It was ok. Not good and not a bad experience

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Stewardess are nice. Food could have been better and should have a better dessert. They do not offer scotch or beer. You have to ask for it. I also was not happy that you do not serve ginger ale and or cranberry juice. This is my first time that an international flight do not have this. I go home overseas every year and when I travel through ANA, Delta, Qatar, JAL, Asiana Air, United Air. they all serve this two very famous drink. You do not have a great snack tray.

Not accommodating ground staff On board slow service Crew members not very friendly

lunch was good; breakfast was kinda meh cabin temprature was way too high new entertainment system but somewhat limited content

We had an awesome flight attendant who came by and made sure we were okay. Checked on us often and even shared some snacks that she had brought on, like edamame with chili and garlic seasoning. Yummy!

Flight was comfortable. The attendants did a great job. I’ve flown on several flights with Hawaiian. No complaints. Suggestion: The egg salad sandwiches seem to be a standard on most flights. I see a lot of them being returned or refused. Seems like a waste. I think Ham & Cheese would be more acceptable.

Overall good experience. I'm just over 6ft with long legs and legroom could be better, but is on par with other airlines. Only real negative was turbulence but that's not the airlines fault.

We were not given the seats we reserved. But helpful attendant at gate gave us very nice seats.

Having movies helps past time I wish going Vegas had something

First flight got cancelled. Got booked for another flight departing 3.5 hours later which ended up being 1hr delayed... The flight was good when we finally ended up flying.

Very friendly und helpful crew. Looking forward for some more flights in

My husband and I had to split seats and I did not like to seat at the window.

The flight was very smooth and comfortable. The entire flight crew was very professional and provided excellent service. Thank you.

Very smooth flight, great landing- entertainment didn’t work so well

There was nothing I didn’t like, prices a little lower would help

BA Airbus A380 BC upstairs had 2 3 2 layout. The seat was comfy but access for those in middle or window seats had to climb over others fest to get to ailse when seats in bed mode. The layout was not nearly as private as other layouts. The staff was amazing as well as the food. Most airline food is average but this was restaurant quality.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Qantas are unable to service and unfit for purpose, they cannot transport Australians on time to overseas destinations. On top of the inflated ticketing, the Sydney flight to Santiago was impacted because the plane was delayed arriving and then further bungling by Qantas admitting the ground new ground crew in charge of cleaning were not trained. The impact on passengers with connecting flights was tremendous and long ques of frustrated passengers waiting for rescheduling. **Qantas has become the Australian Spirit of disappointment**

I was pleasantly surprised with my flight to LA with Qantas. Although seats were not the roomies, service was excellent.

The service and smooth landing. Food was delicious and the staff was friendly. We arrived earlier than scheduled.

Wonderful crew, good food. Absolutely loved the wine spritz and wish I could buy it!

Don’t like last minute airline change. Not able to choose seat earlier.

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.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

The check in from Panama to Houston was good. From Houston to Toronto was definitely an experience. The Pilot from Houston to Toronto was exceptional. He probably saved our lives by noticing a dent in the fuselage. Everyone was taken off the plane and we boarded a new plane

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

We enjoyed that we boarded and took off on time. We didn’t like that our connection flight was a twenty minute walk through the airport with only one hour in between flights.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board

The terminal this flight boarded from was so far away, poorly temperature controlled, and generally uncomfortable. The plane was small but the flight was short, so it wasn't so bad.

Seriously need to improve the time schedule and the plans

Great TV, easy boarding, wonderful ground crew and flight crew.

Pretty good service and US Migratory officers providing services in Canada was awesome, because the arrival was quick and smooth

Rude Customer Service at checkin, 90 minute limit in flight check in is too strict. I was in line for 30 minutes because of slow/insufficient workers. Somewhere I got to the the counter of course the employee warned me about the 90 minutes. People were cutting the lines. No one did anything.

Rouge needs to offer seats with better pitch in economy. Many sick people on a full flight.

Overall, I would have to say my experience with Air Canada was mediocre their DC tens. Need to be updated not comfortable at all. Only one out of my four flights was decent. The staffing was very nice. Going through customs in Montreal was quick and easy. Air Canada has room for improvement with their facilities.

Everything was great. I really like how they had their safety film set up showing you the beauty of the country.

My experience was pretty frustrating because the first leg of my flight on United (though booked through Air Canada) was delayed causing me to miss my connecting flight on Air Canada. This could have been an easy solve as there was a direct flight later that morning via Air Canada that they easily could have put me on which would have only gotten me to my destination 2 1/2 hours later but because United and Air Canada don’t seem to have good communication they gave me the run around both telling me to talk with the other which I did three times to no avail. I ended up taking the delayed flight and getting on a new connecting flight which ended up getting me to my destination 6 hours later and I missed the event I was planning to go to this evening.

I liked the early check in. Flight was a bit bumpy due yo weather. Overall, everything went well.
