The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

The check in was horrible. I stood in line for 1 hour to check in with an Air France ticket. Then I was told I had to go to Delta counter onstead to check in instead. It made no sense.

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

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 .

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

They charge me for luggage which is was included on the ticket

Boarding was smooth and on time. The seat was comfortable and the entertainment worked. Staff were gracious.

Good aorcraft 777 but Worst food ever Breakfast was a bû’with matonnaise… Staff was nice but invisible most of the flight

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

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.

Two flights,both poor. No entertainment. Cramped and uncomfortable seats, little space, the rest was OK. Staff were acceptable good.

check-in luggage charge when they send email for free check-in luggage

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

One of the best flying experiences I’ve ever had.

Both flights were fine. I wish there was a little more legroom, but we got to where we needed to be on time, the crew did their job, and that’s really all that matters. We’ll fly United again.

I like the united App ,easy to check in and baggage.

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

The weather caused a delayed but I was impressed how United did everything they could to try to get us out which included bussing us to the plane doing a Hardstand and bringing us to the plane since the fog was too thick to tow the plane from the overnight stay in the cargo area.

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.

Ridiculous delays with weak excuses. United needs to do their job and troubleshoot. The rate they charge demands no less. Planes are way too full and seats are cramped. Charging for seats and luggage adds insult to injury.

Plane took off without me, my stepdad and a dozen other passengers. It went from an hour delay to boarding in 15 montures without notifying anyone. Names were not called overhead. Now I’m missing a day of work and stuck in Charolette overnight paying for a hotel and Ubers out of pocket

Overall the flights pretty good. The snacks we’re good and they were plenty of them. Both boarding and deplaning went quickly.

Overall it was good. The plane was small and the flight attendants on the Clt to gso route were not that friendly

Poor availability of food. Cold cabin temperature. Extremely long waiting time for a flight attendant to respond to a call button signal.

Terrible Ticketing and Check in process. I learned that AA unilaterally cancelled my premium seating from PHL to CLT and from CLT to JAN. They did, however, refund my money, but my seating was subsequently severely downgraded. They didn’t have a seat for my unless I paid for it! Not cool! Consequently, Check-in took 45 min. AA is usually great, but this was my worst experience with AA ever. Appalling they they arbitrarily cancel my seats threatening loss of flight if I didn’t pay for a seat!!!! -John

We liked quick boarding and on time departure. Seats were very uncomfortable.

Mas información, nos quedamos parado en el avión media hora

While going to Porto Portugal my luggage was delayed for 3 days . While coming back My flight was delayed and missed my connecting flight . No compensation for delayed luggage. Not a happy experience .

In-flight Wi-Fi didn’t work and the flight was 25 minutes late. The Embraer plane I was on was pretty old and the tray table was broken.

Had to rush between flights due to first leg being late, then pulled for additional security screening and attendants were in no hurry, took other people at same time as my husband and I further delaying us and causing additional stress.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

It was great, love the experience and will definitely recommend 👌. Communication was great

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.

It was fine. The seating was tight. My husband is 6' 2", so we were glad to get seats with no one in front of him. I was glad that the plane wasn't packed so I could spread out.

Airport staff super friendly. Even put us on an earlier flight because we arrived early.

My bag didn’t follow me as it was supposed to leaving me without my bag for the first 12 hours of my 3 day trip. My bag got broken during this time.

I really didn't flight from Toronto to Sydney Because my flight was cancelled for the snow But you guys help me lot and put me in the flight from Toronto to Halifax I give you at 10/10 because was really good Just I had to drive 4 hours to be home

Good flight. Comfortable seating, Nice crew. Lots of selection of entertainment.

The agents lied and said flight was completely full, (wasn’t even have full) then proceeded to take everyone’s roller bags even though there was plenty room to accommodate them on the flight.

Tout était bien, comme pour la plupart des compagnies aériennes, le seul bémol était leurs système de divertissement qui a cessé de fonctionner en plein milieu du vol. Un peu décevant surtout quand il reste encore 2h de vol.

As usual with Air Canada, being on schedule would be nice. Tv kept shutting off and having to reset it by staff every time. Irritating.
