I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

The ROOM was great. We would love to have it on all of our flights. LOL

I would prefer to fly with Japanese airlines over American ones. They have better food and service overall

United Airlines crew members do not know how to deal with emergency situation that caused our flight delay. For example, they should have asked the maintenance or seat belt repair personnel to come and fix the seat belt while they were looking for a volunteer to book another flight.

I always take ANA because of the great service and overall experience.

Entertainment and food is best. I love to use ana for a lots japanese movies…. Food was best

First trip from Tulsa to Houston by air. It went by quickly. I watched half a movie and continued the rest on the next flight. Staff was considerate and helpful.

The crew was incredible. The pilots were so fantastic. The smoothest landing I’ve ever experienced.

The flight attendants are always fantastic. My only issue – and it was on my Haneda to Vancouver flight – same as my Vancouver to Osaka flight – I had a confirmed special meal and they had no record of it on board. I tried to confirm it with the gate agent in Fukuoka, where I initiated the day, because of the mess up a month ago, and she said that they can't confirm special meals. I'd have to see when I got on board.

Great transfer of luggage from my flight with Osaka to Tokyo then Tokyo to final destination in Chicago

Better screens, it would have been nice to have more comfortable seats.

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

It was great, but my bag was not loaded onto the connecting flight. I'm currently getting it resolved. If this isn't a problem, everything else was excellent.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

Love flying Asiana. Been using it for over a decade now.

I had a bad experience coming from America to Thailand. On my connecting flight my check in suitcase was not put on the departing aircraft, I received my suitcase 24 hours after arriving in Bangkok and when I open my luggage my hand swelled up. The next morning when I put on an outfit from my suitcase my face swelled up and became numb. My entire vacation was ruined it seems that some kind of chemical was sprayed into suitcase and ruined my clothes and got me sick. The staff at my hotel called the airline and spoke to someone and they told me to file a complaint and gave my a website to do so. I did not file a complaint I felt like it would have fell on death ears. I had to throw away my brand new vacation clothes and suitcase and I had the worst vacation ever due to this happening to me.

The staff was courteous and the flight was very smooth. It was so nice to see the captain greeting the passengers at the end of the flights.

The beefsteak on the lunch menu was excellent! I usually do not eat airplane food. I loved it.

I like them since I live in Alaska and I don't have much choice

The flight attendants were nice, but the cabin and seats were uncomfortable.

Food was terrible, noisy plane & would never pay to fly first class again. Seats in regular price are too small, no leg room & center aisle much too, too small. Seats in 1st class larger but not comfortable.

Overall, once we took off, our flight was good. Flight departure was significantly delayed due to mechanical issues. Upon arrival, it took wayyy too long to retrieve checked bags.

The ticket I purchased through Kayak did not show up in my Alaska Airlines app, and neither of the codes given to me worked for online check in. I've never had to show up to the airport at 6am wondering if I've been scammed. Cheap flight fare or whatever does not play well with airlines and I will be wary of using Kayak in the future.

Crew was rude and passive aggressive when i told them I didnt want to check my duffel bag. Then a crew member slammed my bag to the side when organizing the overhead compartment. The plane had worn leather seats with no infotainment. Plane landing was noticeably rough (this is the one year ive flown multiple times and out of american and delta this was the worst). The only redeeming quality is that we were noticeably earlier than we should have been.

The plane was delayed which was annoying. No seat back screens is a bummer. Staff if great

I got my seat changed last minute so a parent coumd sit with their child wich i found out was a teenager

I wish you would have just canceled the Saturday flight from sea to rdd on Dec 13. the diversion cost me more time and money than if I had just rebooked to Sacramento. It was a huge headache and cost.

There was no food or entertainment so quit asking about that! Everything else was fine.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Late delayed flight delays boarding and delays leaving and delays on arrival too. Cramped plane no room no food.

DTW line is too long. The flights from DTW to BWI are always delayed for unknown reasons.

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

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

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

Flight was delayed several times. At one point, they "pulled back" 15 minutes from the delayed boarding and sent a text saying we would board sooner than previously advised. The flight then was delayed again. And when we boarded, there was an unspecified technical issue which had us waiting in the plane for about an hour.

Delta is a good airline. I've never had an issue with Delta. I'll continue to fly with them until they show me that I shouldn't.

The only thing nice I can say is the flight crew was really nice and apologetic about the situation. They shared as much information as they had and advised us on what we could do about missing connecting flights. The boarding process was so slow. The gate agent was working by herself and should have had someone working with her. It took almost an hour to board because she was trying to board a full flight of people and provide customer service to everyone who was flying standby and/or had questions. It was really chaotic. This didn't help the fact that we were delayed and folks were missing connections the longer it took.

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

Going to Tokyo was not so good. Back to Detroit was excellent.

I’m so sorry, I can’t remember her name, I believe it was Dimpti. She was stellar, also a mature Asian flight attendant, lots of flowers in her hair, just as amazing! But literally the crew was AWESOME . Only downside is there weren’t any charging outlets. Maybe I needed to ask a flight attendant , but it would’ve been nice to have one easily accessible.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Everything was absolutely wonderful from check in to baggage claim. Staff was very professional and sweet. Will definitely recommend United to family and friends.

Aircraft was noisy, old and never dimmed the lights on a night flight even on business class! I flew 17 times on United and probably another 40 on other airlines United USA /Europe flights were the worst to include luggage delayed once going to europe and once coming back

Check how old the airframe is, some older ones have inoperable seat back entertainment or power.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.
