My son’s suitcase was left behind at SFO and did not make the flight.

My son’s suitcase was left behind at SFO and did not make the flight.

Seats were not bad enough and uncomfortable good legroom in the emergency exit row we were in, but we were forbidden to hold my grandson on my lap for a little while, and the stewardess passed us saying it was against regulations which makes little or no sense when you’re 36,000 feet. The food snacks were really bad. Tasteless tasted like wallpaper, but we’re supposed to be protein bars, and the announcements were all completely incoherent because of the noise of the airplane and the lowness and crackly nature of the PA system.. this was disgraceful. No one in our party could understand a word of what the captain or the flight attendant were saying —not a word! The landing was a little hairy in a pretty stiff crosswind -we bounced before the plane stabilized on the runway

Chaotic boarding at these gates, multiple gates squeezed in at the very end of a concourse, behind a restaurant. Agents gave up on boarding by individual zones. Flight itself was uneventful, which is all we hope for any more.

Unprepared to rebook a flight of people. Uncommunicative. When I received updates in the app it was well after the announcement in the hold room. Offered a single $12 meal voucher, not enough for a sandwich at DEN, for a 17 hour delay. No one was able to explain their meal or hotel reimbursement policy for this cancellation, just handed a card to call the Help desk. My previous flight went through several delays and was finally cancelled, without explanation. The customer help desk closed while there was a long line. I then waited in line for a gate agent almost an hour while simultaneously on hold and trying to text with a remote Delta agent. Communicating with the text agent was almost impossible; they could not find any flights that got me back to my original city before the following evening. Kept offering itineraries that did not get me back to my origin airport or involved additional layovers. In 50 minutes on hold, never got through to an agent by phone. Finally spoke to one of the gate agents who was able to rebook on a red eye that had only one stop and got me back in the afternoon the next day, rather than late evening. Later by email, Delta offered 10,000 loyalty points for the inconvenience of the cancellation. The crew on the red eye flight were delightful. I don’t remember any food or entertainment on that flight.

Flight team was great and we even arrived ahead of plan!

It was good delayed again but once on board the flight crew were very good the entertainment and wifi worked on this plane and we were offered snacks and drinks

The boarding agent guy in Lexington on 7/23 that boarded the flights to Atlanta is very rude for working in customer service. I know there were delays but he was dismissive rude and arrogant. Most native Kentucky residents are nice and very cordial he needs to eat a big ole piece of humble pie. I watched him be rude to several people and as much as he could of filled up a delayed flight to save you money and he was so rude to people it was ridiculous. Next no water or snacks on short flights is awful 1st you delay a flight then do not even offer water on the flight.. No thanks I like delta better but I travel ever week and to be treated like this might as well fly American at least they offer water and have better rewards.

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

Gluten free snack options and meals that offer both gluten free and dairy free.

The pilot was late so we didn’t take off til almost 2 hours late.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

The international portion was good. Food and beverage options were good. The sustainable wooden eatery was less than desirable. Your Star Alliance partner ANA provided real silverware. I'm 6'3" & 198 lbs and felt cramped in the exit row. How can that be? Flight attendant all had a pleasant disposition which is always good.

The male air hostess was rude and didn’t provide good customer service. Didn’t even offer me a drink

This trip was a Christmas gift to our family. We were flying from Lexington to Palm Springs. When we were checking in the ticket agent said one bags was over weight by 4 LBS. We were flying first class which has baggage weight of 70 LBS per bag, one bag was 54LBS. We then had to take items from one bag to another. The agent also saw we had a dog with us. Once on the plane we were seated with the dog in the carrier. The United ticket agent came in the plane with two other people, I believe one was TSA and the other some security officer. The United agent said we had not paid for the dog ticket. We had paid for the ticket when we purchased our tickets. She did not give me time to find the email receipt. She then threatened all three of us with either I come with her or she would have all three of physically removed from the plane. I left the plane to pay for another ticket. She had to take my credit back to where we checked in. She acted as if it needed to be done immediately. She said we had 3 minutes. We then sat at the gate for approximately another 45 minutes. This was so embarrassing…to be threatened to be removed from a plane that we paid for all tickets including the dog. The flight attendance on the next leg of our trip were not very attentive to the passengers. On the plus side all the flights were on time. All in all, this was a miserable way to start a holiday vacation. United Airlines showed no compassion towards the whole incident. I feel we were purposely neglected.

Patrons with larger bags were asked to check the bags when boarding. Seems like the most effective, and least costly way, way to successfully use the cramped space.

Better perks for corporate employees whom travel often and spend a lot of money with the airlines. Snacks were terrible chips crackers are ideas. Flight and crew were great comfort was fine entertainment not so great so so called status members means nothing

Flight had mechanical issues and it was delayed 30 mins - some of us boarded and then had to deplane.

Delayed flight. Missed connection, AA put us on a later connecting flight. The connection flight was delayed 4 times and we had to deplane. Didnt get home until 3am, when I was supposed to be home at 8:30p. Zero compensation offered from American. I would not fly them again.

Better snacks but flight and crew were amazing on this flight

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.

Cabin was roomy enough to easily slide my carry on under the seat in front of me!

They needed to de-ice the plane. Apparently airlines have a problem keeping their de-icing vehicles in good repair. After we backed away from the gate we sat and didn't move for nearly an hour. Nearly an HOUR with minimal communication from the flight crew. Eventually the sun took care of what American Airlines could not and melted the minimal ice. We finally took of a hour late which, in turn, jacked up our connection in Chicago.

We were delayed in Charlotte for almost 2 hours because American Airlines didn't have flight attendants for our flight.

The crew could deploy more customer focus and not frown when asked a question. I’m speaking of one lady in particular who raised a hand in my face for me to wait whe I tried to ask a question and never came back to me. Very unprofessional and rude.

They set someone on our assigned seats and we ended up finding seats for ourselves to ensure the family sits together.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Aircraft had fairly roomy seats on economy. Food was good (beef dinner).

Broken seat did not recline fully, broken footrest, no air vents, no electricity for charging devices, outlets for headphones or isb did not work. Rude crew. Horrible experience. Would never fly Lufthansa again

The Discover flight from TPA to FRA was exceptionally unprofessional and incompetent in organization. First the entertainment system was completely nonfunctional for the entire plane and no competent IT support to fix. Than they could not serve any coffee or tea because they ran out of water - reflecting the exceptionally incompetent management at Discovery and most embarrassing for Lufthansa and a German airline, more like a third world country. The food was mediocre at best and minimalistic for Discover, particularly with the much higher standards at Lufthansa.

Lufthansa's Miami International counter folks are very strict on carry-on weight. Can't be greater than 8 kg otherwise they force you to check it for a fee. Bags came out at baggage claim as soon as we arrived to that location (it is a far walk from arrival gate to bag pickup). We do travel with Lufthansa domestically and enjoy every trip.

It was okay. Mothers with rowdy children should be invited to sit in front of them.

It started well but flight was cancelled and they created a nightmare rebooking. It is two days later and we still haven’t reached our destination. I am in Amsterdam waiting on transfer desk to open (later than other airlines) to hopefully get a boarding pass. Once that problem is solved we will just pray this flight isn’t cancelled too.

The flight was cancelled, so why are you asking me how the flight was?

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.

They gave away my business class seat. No explanation and no apology. Told me I had to take the downgrade if I wanted to get to India. Then no WiFi for 10 hours. Just ridiculous. We should not work with this company at Deloitte. They don’t know how to run a business.

ok. It's a short flight and it was delayed, hence the ok rating.

Would like to see clean bathrooms, especially the bathroom by the end of the crew flight the cleanest not the bestest thank you

Wonderful. It seemed so quick and the view of Mt Hood was really good.

Work being done at DIA made it difficult to find BA desk.

The airplane was refreshingly silent in flight than Airbuses, landing was very soft and secure. Food was also warm and light , not a big fan of curry though. Staff was polite, discrete, professional and helpful.

I was booked in Premium Economy and never given a chance to choose to purchase my own seat. Ended up with a middle seat, which was very difficult for me. The airline then left my bag in London so when I arrived in Instanbul it was not there. They delivered it to me the next day but many valuable items had been stolen. I've been flying with BA for years and this was the first time I had such a bizarre and bad experience with them.

Flight got cancelled and we did not get an email till the last minute. They rebooked us on British Airways for 6 hours later and did not inform us. We drove all the way to the airport for the AA desk attended to take a while to figure out our flights were cancelled and rebooked. British airway attendants did not show up till 4 hours later! Really poor customer service

Meh. Lived the seat. The entertainment unit did not work and had to be reset 3 times. Service was SLOW taking over 90 min to be served. Crew forgot about my meal. Chicken was dry and almost inedible.
