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.

They wanted to close counter although they did not provide the wheelchair requested which ended by going alone to transit security and lost long time and they did not want to wait .

Everything went smoothly with Air France. There was a delay in departure which seemed to relate to the immigration services being short staffed.

worst experience ever i choose my seat in advance and also have my seat selected in my boarding and the they told me that my seat has been changed without notify me

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 birding 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

Lost luggage, 2 bags were badly damaged and one of the bags came open.

their gluten free lactose meal is the best, I have never been satisfied with my flight meals. I definitely enjoyed my flight and the chair is very spacious for economy. I'm so glad Delta is my flight way back to NY.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

Your app is impossible to use. I couldn't load it. Then i couldn't open it. When i finally got both those things done -with much help -then i couldn't open the app to install a credit card. The upshot was 4 flights without access to food or drink. When i first tried to download united app some company called starlier opened instead and i would up signing up for some 49 dollar a month music service which i still have not been able to cancel.

Other than the two hour delay, it was fine. Of course they were very professional and kept us informed throughout the whole delay..

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

The original seat on the flight Toronto Newark had the floor flooded with coffee spilled, so they changed our seat to premium economy. For the flight from Newark to San Salvador we were i the last row, no reclinable seats and beside the toilet. I asked for headsets to the waitress and she gave it to.me test of all the passengers, while she was staying right behind me..

United requires seat selection in order for those booking together to stay together.

Did not like the seat spacing. The seat was very narrow and tight.

Delays!!! Maintain your planes so your customers don’t have to sit on their assess for over an hour on the tarmac!! Also, United app is buggy. Videos did not load. Overall a miserable experience. Flight crew was awesome though.

Crew was wonderful and attentive. Chris (I think that was his name as I was seated in the back in 52F) was amazing and funny. The captain was informative and did everything to get us to Denver as close to on time as possible. Bags came quickly at baggage claim. Online check in would not allow me to change my seat 24 hours ahead of time with dozens of seats showing open and I really do not enjoy being in the back of the plane for long international flights.

We were told our seats were switched which put us in row 1 instead of 12. We were not able to keep our personal items with us. This caused us not to be able to have our gum to pop our ears and we weren’t able to get our iPads out due to the seat belt sign never turning off.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

Late arrival due to gate being blocked by stalled truck

Delayed flights and lost bags. It was a terrible experience this time.

Considering the weather issues. It was great. Over all the 13 flights changes

Help was available but timing was bad in my case

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 flight from Guadalajara to Dallas had mechanical issues, and was delayed every half hour for 4 hours until we were told to rebook. As it was during the busy holiday break, most flights were fully booked and travel that day was unavailable. The only saving grace for American Airlines was their ticketing staff that maintained their composure and did their best to accommodate all the disappointed and frustrated passengers.

It was Christmas and the crew was awesome. And the passengers were patient.

Horrible trip. I won't fly AA again Boarding was a nightmare because they squeezed people into the waiting like sardines. My connection was 30 minutes and the run to the gate was horrible. Then the flight was canceled AFTER boarding. The Flight attendants did not know what to do and gave out the wrong instructions. They finally sent us to a different gate. Again, the waiting was like a sardine tin. The flight was okay and my baggage arrived fine.

The flight got canceled multiple times and we had to drive their to reach midnight for our next morning interview. Poor and unriable experience. Now have to ask for a refund since we didn't need their rescheduled flight three days later.

Seating is comfortable, boarding is well organized. Toilets are very small. Even though I’m petite, still find no room to move around. Toilet paper holder hanging loosely, eventually they fell on the floor. The small sink is too shallow that causes water splashing on the floor. It doesn’t look pleasant. I didn’t purchase food or watch the entertainment, so no comments.

The boarding was done smoothly. This flight from Puerto Rico to Toronto, a light meal should be offered to the travelers.

Not happy with Air Canada . Flight was cancelled got the run around trying to get another flight that was direct none to be found ended up going to Denver then onto Austin adding 7 hours to our trip. Was travelling with some one who had walking issues that’s why we were happy to have a direct flight then it didn’t happen adding more stress on her

It has space for legs. Comfortable seats Punctual Some snacks should be served

I really find they have good service but need to serve meals on flights longer than 5 hours. Very cheap of them as I am a large stock holder and find they can afford it. Really like tracking my bag and the updating of flight info etc on my text and emails.

Mostly crew good and the flight was safe and comfortable but service was lacking. For an overnight flight of 8hrs 50 it took some two hours to get served a drink and dinner after take off. I asked for Laurent Perrier champagne and was brought Perrier water, which I queried and asked where was the champagne. No response. The issue came up again an hour later when dinner was starting to be served and I was asked whether I wanted another drink, when I reminded I was still waiting for my first champagne! Apologies ensued but dinner service was quite slow. For breakfast I never did get served the hot course! So - no complaints and compliments on the safety of the flight but service underwhelming (and I brought them candies!)

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

Food in Air Canada can always be better. Processed packaged foods are so 80s.

My flight has been canceled and I had to cancel entire trip.

Check in was horrendous! Economy took 2 hours before seeing an agent. Business class was 0.5 - 1 hour.

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

Check in process was unfamiliar. While receiving assistance the employees supervisor berated him for not walking the area. Lucky for us, he ignored her and helped us check in. Did not know about the baggage fees with economy basic and spent 450 GBP (nearly$600) just on bags for a total of less than 2 hours flying time (50 minutes one way) on a round trip lasting less than 3 days. Astronomically high price for bags. Our first experience flying British Airways and very disappointed. Completely overpriced for the service we received.

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.

It said that there was wifi. During the flight there was no wifi and while waiting at the gate the phone services already got cut off so I wasn’t able to say I am taxiing from the gate to my husband. This left me with an uncomfortable feeling. So I was waiting on the WiFi connection during flight and that never happened.

Asked for a wheelchair multiple times. Got denied the wheelchair in London layover.

No entertainment available on flight. Seating too cramped fir an average adult.

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

Staff , Comfort and Food were excellent. My individual lamp did not work so I could not read, neither my novel nor the menu.
