The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

Korean Air had great service and the Bibimbap dish was the best airplane food I’ve ever had. It was a long flight so in between the two meals they served customers could get Shin ramen. The flight attendants let my children use a pair of nice headphones for the flight and had earbuds and slippers for all the adults. The flight was long but the time passed by relatively quickly because they have many great shows in their entertainment TV. I watched the BTS Love Yourself and Speak Yourself concerts 💜

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. :-(

You did not put me on a Korean Air flight! so I do not have nothing to say

My flight was diverted to Atlanta and I was not given enough time. I paid my travel on April 23, 2023. It was originally Delta from Norfolk to NY, then Korean Air from NY all the way Philippines which is my final stop. Instead from Atlanta to Korea I flew Delta which is okay. Then Korea to Philippines, I flew Asiana Airlines. What I did not like, Ieagle did not sent me an email that my flight was change and so when I went to check in Wednesday the 10th, at 4:30 a.m they told me my flight was delayed at 6;00 p.m and diverted in Atlanta and I am flying Asiana from Korea to Philippines. I do not appreciate that Kayak or Ieagle chenge our flights 5 times and then last minute change again during my day of flight. I hope that you will not make any changes of my flight o Feb 15th because it has to be the same flight with my husband. That is the reason why we made the arrangements early on.

Wonderful cabin crew!!!!! Food was poor, in flight entertainment was just ok. They need to serve more water on a 15 hour flight--we were dehydrated and kept asking for water.

Going through security a third time to get on the next flight was again utterly ridiculous and unnecessary. We were in a International secure area once again and as far as I'm concerned should not have been put through the gears for absolutely no reason. The United States can get all the information they need from the travel itinerary, there was no need to be forced out of a secure area to personally interview everyone on a connecting flight to find out their US immigration status.

Flight arrived early, fantastic, since it is short flight, no food being served

My experience with Scoot is very good. Will have no issue flying with Scoot again.

All in all the flight was good. Love the fact that for airline food it was piping hot

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

It was a great flight Food was great Crew was spectacular

In general good, but the machine seems to be long in operation and some functions were restricted as e. g. Adjusting of seats.

It seems paying premium economy does not make difference with economy. No priority boarding, not worthy paying extra$$$ for premium economy.

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

Flight was delayed 2.5 hours - a big deal on an overnight when you plan to sleep.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

First time flying Air Canada and the trip was very pleasant! They did a great job getting us out of Toronto and into Rome (early!) For an international flight it was very enjoyable.

This is not a Business Class equipped airplane and even the crew apologize before take over BUT BUT Air Canada charged full business class fare

All was good, except our baggage was lost for most of a day. We are thankful that it was found quickly and delivered to our hotel. Rouge was fine outside of that problem.

You do not have a space for flight cancelled. BUT!!! Air Canada handled it great. Was booked on another airline for the next day. The original flight was booked solid. But he precheck by the maintenance found a mechanical problem and the plane was not safe to fly. It was an inconvenience to have to wait until next day but I would rather arrive safely.

Very good other than we have to wait for one crew and we’re delayed and the pilot and his co- pilot has to make a difference to be right on time arrival. Disappointed about no food service also.

I had written all my complaints on my trip from Grand Junction to Denver so I will repeat it here! I was absolutely appalled that I had to pay for a regular seat that I choose 24 hrs before boarding! Also I checked my large bag which I had to pay for as well, and by the time I boarded all the room in the bins were gone so also had to check that one. I noticed people pulling out oversized suitcases, bigger than the measurements stated for carry on, and also large pack packs stuffed full! So these people were taking up 2 or 3 spaces that the rest of us should have been able to use but couldn’t! NoTV on the flight! Thankfully I had downloaded the United Airlines app and was able to watch movies on my phone. Don’t remember the last time I flew in a plane with no movie screens!

I was appalled to have to pay for just a regular seat when I went to book 24 hrs before my flight! Because it was only an hour flight I didn’t choose a seat from Grand Junction to Denver, but I did for Toronto and had to pay just to choose a regular available seat! In my 60+ years of flying this was the first time I have heard of this. Also, allowing people to bring on “huge “ suitcases, not carry on size, but much bigger, and then a large pack pack stuffed. So they take up all the room in the overhead bins and if we are later boarding, there is no room so we have to check our small carry on. I have already paid for and checked in one bag! I certainly will not choose to fly with United again unless it is the “only” airline available!

Easy boarding, roomy seats, plenty of good food, very helpful snd friendly staff. Very smooth flight! Only thing that could have been better was to have cranberry juice. Women like this as it helps avoid UTI’s and not as sweet as other juices.

The crew was friendly, the seats are too small. Air travel is barely tolerable anymore.

Food was icecold or frozen including breakfast. Hopeless service. Rude crew.
