I loved everything, I was just a little confused on my bag allowance. When I checked in it said I was allowed 2 check in bags, but when I got there they said I was only allowed 1 so I had to pay an additional 200 dollars! Other then that everything was great! I would love to use your Airlines again when I fly out to Manila again in late May, however I want to be able to have 2 bags included this time lol 😆

Need to have space for Cary on when traveler boarding any zone

everything was fine, would have liked better food but it was warm, great choices for movies

the water for tea could have been hot, entertainment was awful, lots of old movies and TV shows

The carry on baggage was collected before boarding without further information where the passengers can collect them . When the flight arrived at Tan son Nhat airport, it was very complicate to find the luggage

I like it when the plane have waited for passengers like us who are trying to catch the plane. Detroit was my mom's port of entry we spent too much time looking for our luggages at baggage claim which no problem. But then the problem occur after the immigration when the homeland security agents forgot to give us our passports which it took so long to find them and I was very anxious because we might not be able to catch our flights but luckily the plane to knoxville still sitting there and waiting for us. Praise the Lord for everything.

I took several flights that day, this was the only flight that was absolutely freezing!! It was so cold.

They changed aircrafts and they moved my seats that were already prepaid. I did not get the seats I paid for, so I got expensive seats that I didn't want

The flight was at least 3 hours late with not much of an explanation other than connecting flight was late

Good. Obviously there is a slightly condescending attitude of all American workers towards their customers but other than that all good.

We took business class, It was comfortable and I was able to sleep.

Everything was perfect. A flight attendant even brought me snacks after I declined food due to my desire to force myself to follow the destination time zone.

For the most part, it was an enjoyable experience. It's the 2nd half of the journey was a bit uncomfortable. It was on a noticable smaller plane compared to the previous one.

Only process that my luggage didn’t make it to my destination because of short connection but I understand

This has been the worst experience I've ever had. We arrived to Ho Chi Minh Airport and were supposed to get our Asiana ticket from the transfer counter as we came with a different airline. However, the staff at the transfer counter were not helpful and kept giving us different information. We were first told by Asiana airlines staff we had to wait 2 hours so they could print out and give us our tickets, then someone else told us we had to wait 3hrs, someone told us "I don't know, just go sit and wait and we will tell you later." This was at a place in the Ho Chi Minh airport that had no coffee or food shops, nothing, just immigration (to enter Vietnam with a Vietnam Visa) and security (to transfer into the gates) but we needed our printed boarding pass to go through. It wasn't until we demanded to speak to a supervisor as our flight time was 1hr away because they kept telling us "there's alot of time left for your international flight, we will get your tickets later" we still had to wait around 20minutes for the "Supervisor" to give us our tickets. I would NOT recommend Asiana Airlines, especially if going thru Ho Chi Minh Airport as they are not helpful. (We almost missed our flight, due to their lazyness and incompetence of printing our tickets) I would suggest Asiana Airlines to have a Machine in the transfer area so passengers can easily print out their boarding passes themselves and save some money by not hiring incompetent staff that can't do a simple task such as printing a boarding pass.

Great service. They could offer vegetarian food and do more to reduce waste.

I like the food, the crew and everything.!!! Except for the delay in our flight.

Great service and comfortable seats. The first meal was excellent but the second meal was only satisfactory

Typical Asian airline - flight attendants like robots - start food orders at first row and get to the last row right aisle last - no food selections left. 30 minutes before landing demanding everyone put seats back into upright position, window shades open and God forbid you might have to use the restroom a full 30 minutes left into a 1 hour 45 minute flight. At least the flight was cheap - but that’s the best I can say about it.

Check in agent very rude, no greeting “Hi” or “ Thank you. Doesn’t direct where to go for gate info. In flight crew staff not friendly. Very disappointed ☹️

Well, this is my second flight from THE first one that I took and this one was from Manila to Guam. The flight was comfortable. I did end up in first class. However, I had to fight for it a little bit, but when I went to Guam, I had to stay an extra night there, which was accommodated by united Which I'm pleased for that. The only thing that I have to say is when a situation happens with a cancelation. And you got first class guests very important that you accommodate and make sure that they have their flights before everybody else does, because we pay big money for the service and it is not cheap also. Take note There are things that we have planned as well. So this kind of damaged the tail end of my vacation, which I lost out in $2500 worth of car rentals hotel fair in Honolulu, Hawaii. I'm really hoping that I can be reimbursed at least that money from the insurance that I have on the trip through united. I will be submitting that in as well. When I'm back in the United States, because I'm currently in Guam. Staying good night. I'm waiting for my next flight out. For tomorrow morning..

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Very modern plane. Good seat spacing. Meals were good. Screens had tons of movies and worked

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Beijing PEK to SFO. I had an economy seat on this flight. The seat comfort was acceptable. My main complaint is with the FA’s lack of personality and absence from servicing the plane, specifically restroom care (I wish I could share a pic of the restroom that I captured) and care of travelers—drink cart/availability of drinks. I'm amazed at the level of service on other International travel where a passenger is most often appreciated.

the pilot that landed this flight in Philadelphia did an amazing job, the weather was absolutely terrible and we landed safely.

rushed onto the plane by inpatient staff just to sit on the taxiway just want to add, the flight out of Philadelphia and into Fort Worth Texas was terrible. canceled twice because of non-existent weather, and delayed.

I blame kayak for my last trip to dca. Kayak cancelled my direct flight and put on a one stop flight and made lost whole day from my vacation and had not even refunded my ticket.

late again! but its my only option to not take 9 hours to get to Memphis

Per usual, flight status, staff courtesy and professionalism were excellent

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

My flight was cancelled and I was left to figure out where to find a hotel, something to eat and how to get a new flight at 11:30pm. Wasted a day. Thanks, Air Canada!

flight was delayed 6 hours for weather, then cancelled because of the crash in toronto, but none of the links to cancel or rebook my flights are working

They kept changing the gate (6 times in 30 minutes) and then left us on the plane for 4 hours before departure. Likely was the storm, which is understandable, but the lack of communication and the e constant running between gates at opposite ends of the airport really threw me and my friend for a loop.

Legitimately everything about this flight was awful, was also so delayed I never want to use air Canada again

Terrible all around. Flight was late and airplane was very uncomfortable. The crew were unhelpful and hid in the back. Did zero work. No entertainment.

Because I am quite tall a bit more leg room would have been more comfortable. Out of three seats I had the middle one, unfortunately.

I like the free beer and wine but not the delays to the departure time.

Never again flying economy on Rouge!!! Literally like sardines!!! Will try to change to better seats 3 seat arrangement only so so if traveling with family. Who wants to squished to stranger!!😖 Can’t say enough bad about this!!!

I booked and paid extra for exit door seats also pre paid for my luggage air Canada changed plains and I never got what I paid for and they made me pay for luggage again they also did this to my wife. They are the most unorganized company I have ever dealt with. I am sure I will never see the extra money I paid for the seats or the recharge for the luggage. They are subsidized by the taxpayers and don’t give a dam just a horrible way to do business

Overall the experience was excellent. Plane was clean but more importantly quiet. Recently, I’ve noticed that Airbus planes seem quieter than their Boeing counterparts. I definitely prefer flying in an Airbus plane.
