Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Medíocre. The food wasn't good (although not bad, bad) and the staff wasn't kind. I asked for n extra blanket, the steward never came back, serving us roughly.

Generally good. The crew is excellent. The food could be better.

Food could have been better especially the breakfast. Overall it was a good flight

I have used Air France and KLM many times it will help if they change their menu's feel like it's been the same for years!!!, Especially the breakfast. Overall the flight was good and enjoyable.

No bording was given for next trip on same carrier, food was very moderate.

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

The line at boarding was not well organized and managed

Sky priority means you get to use the KLM business Lounge.

Je n'ai pas pû incliner mon siège et une des hôtesses ne comprenait pas ce que je disais. Je devais parler fort

The crew was great and handled our unexpected detour with proactive communication.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Pretty turbulent, but not anyone’s fault. They got us there. Impressed that they carried on with a drink service.

The male air hostess was rude and didn’t even offer me a drink. Poor customer service!

Poor customer service & placement in seating row with less leg room than we paid for.

I was very fortunate it was not a full flight , so I had 3 seats to myself. Absolute bliss. Food very good. Except dinner desert was a sugar bomb. Can you provide yoghurt or some healthier dinner desert. Thankyou

No comfort, local flights chair in use on international flight, food wasn’t nice.

It was your usual flight. Nothing exemplary. Due to turbulance, the drinks were served 20 min before landing. Meh.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

On time from BWI to IAH but delayed over an hour from IAH to AUS without reason.

I'm a person with a visual disability and I felt safe traveling on United Airlines. The flight attendants were very attentive and checked in on me to make sure that i was accommodated well. I had a connecting flight in Chicago and I liked the ease of boarding on and off the plane. There was no issues at all. I'm very pleased with my flight experience.

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Well, flight times cause some wait, but there were not times available and we understood. I didn't check any luggage, because it has become too expensive. I was able to add any extra items to my co-travellers check bags. [Luckily, this trip wasn't international.] Last, I hadn't flown AA domestically for a while, but partners and coworkers had warned me in advance that not all planes have monitors at every seat. Luckily, I was mostly prepared to use the in-flight entertainment and happy I was. The great: AA staff is always kind and comfort is way better than the budget airlines that I sometimes have to fly. I know my points and vouchers all expired over the last couple of years, but I still enjoy AA when I do fly with them. I also appreciate all of the locations we can go directly from pur home airport. Since we are traveling more now, I hope to take advantage.

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.

The person next to me used my leg space up and made it an uncomfortable ride the whole time

On time flight , great service from crew , comfortable and enjoyable

Unfortunately we had turbulence because of the weather and when we were about to land in Miami, the pilot brought the aircraft quickly up because another plane was in its way. The pilot was remarkable however we weren’t told until we started our second descent. Our flight was GOOD

While it was a fully booked flight, the first class flight attendant provided those seated in first class with a beverage during boarding and quickly started service as we climbed to altitude.

The flight was uneventful, which is always good. The plane was clean and seem to have a little bit more room. They fed us every couple hours, and we had a lot of in-flight entertainment. The staff was very helpful and attentive.

The business class configuration on this plane is really contorted and tight in space. To have to climb over another’s feet to go to the restroom was less than comfortable. Also, I was served meals handing all plates and drinks in front of the random flyer facing me on the aisle. I felt it was an elevated comfort + economy cs business class. Also, the interface at Heathrow is awful. The lounge had minimal plugs to recharge devices and it was so crowded, There were few seats available in both the North and South lounges. Rarely anyone came by to clean up after the last 3-4 people who sat in that chair.

Food are bagged dry snacks in business. Entertainment did not have live tv line in other domestic flights.

I go am isle seat because it was half empty Food strike no food available

Flight was delayed 1.5 hrs due to problem with a previous flight to mine; I was informed appropriately via Text & Email, however, website did not keep up with messages sent by nearly an hour. When checking-in warm & friendly reception at check-in desk until female Air Canada Rep noticed my flight number and instantly pivoted to a condescending & sarcastic comments about getting my bag checked in since I’m running so late; then tone instantly changed again few minutes later when she muttered, “Oh, they’ve delayed it” another sign systems & worse front line staff, not fully informed or simply not reading their flight status updates. Flight crew were very friendly & did a great job trying to make up lost time due to the delay.

I didn’t fly I had to cancel as I booked the flight incorrectly, as in reverse order. I hope I wasn’t charged as I cancelled immediately.

Lovely staff for a short flight! Complimentary wine too made me happy.

Bye portaction for cancelation , when you want to change date, you have to cancel And pay 20% as cancelation. To lose as cancelation!!! Upsell airline!!!!!!!!!!!

Bad. Staff needs training on hospitality. I was on emergency flight and being s vegetarian had no food served. Air Canada should carry at least additional neutral trays of food.

It was a refreshing experience from the past few times I have travelled with Air Canada.

A delay in ETD that is not part of the flight , that could be managed.

No food on this short flight No entertainment, not even a USB to charge a phone or use a tablet.

Nanaimo to Vancouver was fine but flight from Vancouver to SFO was not so hood. Major problem besides 7 hours of weather delay was the fact they let 4 very drunk men on the plane into first class. They were awful! They should never have been allowed on.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.

The crew was very attentive and kept busy serving a variety of treats!

The boarding process was a disaster. No one respects the boarding groups—tired old aeroplane. There are no sockets to charge phones. The cushion seats are ancient and hurts back and gluts

This was an American Airlines flight. The crew were very unhappy and quite grumpy. Abrupt to the point of being rude. The food was dreadful. Indeed the breakfast was in edible. I will avoid AA at all costs in the future.

Annoying customer pushing my seat did not make this pleasant.

The flight was delayed numerous times with inconsistent updates and very ambiguous information. When it was finally cancelled the logistics of handing out vouchers and rebooking was extremely chaotic. Meal vouchers were completely inadequate for the airport restaurants, and not even accepted at some. All-in-all, it was a very disappointing experience.

The entertainment system in the plane ✈️ didn’t work in our row… makes for a MUCH longer flight.

Pre flight food options were not working and made the flight not enjoyable. Post experiences of British airways have been positive, but this is enough to stop me using British airways again

Everything was fine except my screen wasn’t working and I was unable to watch any movies or TV. Staff tried 3 times to reboot it, without success.

Too many passengers are bringing two large bags, neither fit under the seat so space is limited and the crew ask for many people to check bags
