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

When I selected my seats, it showed row 29 as the front row, so I paid extra to sit in what I thought would be the front row, but when I boarded the plane, row 29 was the second economy row. I was disappointed that I'd spent almost $100 more for no actual benefit.

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

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Everything was ok!! Just bags came up a little be late.

Tasty snacks. On-time departure and early arrival. Luggage arrived quickly at the carrousel. The only negative was a man behind us that was heavily inebriated. He was served 3 double drinks during the flight. There was no telling how much he had before the flight. He was so out of it that he spilled a drink and broke the heavy liquor glass on the floor. I don't believe he should have been served so much alcohol on a two-hour flight.

Kind staff. Snacks are small but that’s the new normal.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

The crew was very kind and always smiling. The seats were great and I was very comfortable during the flight. The only thing I didn't like was that the lavatories got really dirty at some point during the flight. Other than that my experience was great

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.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

United left one of our bags back in SFO but that’s not my real complaint. The complaint is how it all went down. So we checked in the day before online and were told we could use the quick drop for luggage. So the next day I used baggage quick drop curbside at SFO. The agent mistakenly didn't tag my bag as he put my bag on the conveyor belt untagged. We immediately alerted him he had not tagged the bag. I walked with him to the baggage service office to find my bag and tag it. We waited outside the office for 10 mins. He came out and said everything was ok and the bag was going to be tagged and on my flight. We received a text that one of our bags was on the flight but the other was not. I alerted my first class flight attendant immediately upon boarding the flight. She was helpful and said she’d get it sorted out right away. She called over the gate agent. The gate agent used my bag number and looked over information on her device. She said my bag was on the flight. The flight attendant was standing with her, looking at the device, and also said “yep it’s on the flight”. During the flight the flight attendant made reference to how reassuring it must feel knowing the bag was on the flight. Upon arriving to IAD we received a text that my bag was not on my flight. The text said my bag would arrive to my final destination LIS 24 hrs late. I understand that mistakes happen. I was totally ok with my bag mistakenly not getting tagged at the quick drop. I was fine with walking down to baggage services to tag my bag. But, what I am not ok with is that the United staff said they fixed the mistake two different times, assuring me twice that my bag would be/was on the plane…and it wasn’t. I expected better attention by the employees, for them to do what they said they were going to do. We also spent extra money to upgrade our seats to first class, including the entire return leg from Lisbon to San Francisco because we wanted a smoother and more relaxing travel experience. Our money was not well spent. We will not be using United for travel going forward.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Horrifying! And I am almost 2 million miles with United. Late by 3 1/2 hours. Worst: after two hours on the plane waiting, they decided that one of the tires had been damaged and then decided to change it. Another hour and a half to change the tire!!!!! NO EXCUSE FOR THIS. The crew didn't even offer a glass of water until we had been on the plane for FIVE hours. This is the worst airline in the world. I'm simply stuck because they fly on the only routes I need.

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

My experience was medium staff where great I dislike flying in triple 7 seats very uncomfortable and no room on jet all the rest of the flights where great

Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Sucks ! All three flights I was on this trip were delayed.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

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.

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.

AA can't control the weather. But the airplane was hot and stuffy while stuck on the runway with a broken entertainment system.

very bare bones flight no entertainment screen, download shows prior to boarding to watch on phone or tablet.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

Service in first class no longer exists on American Airlines .

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.
