This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Nothing special. The crew never went out of their way for anything.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

I believe that a four-hour trip should have a meal. Delta had none.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

Armrest controller on my seat 35D and nextbooennseat 35E did not work right. Hard to press buttons to recognize and 35D had constantnpressure either upmost down somit was nearly impossible to make selections. .

I flew with my dog and had already purchased my dog’s ticket. Even that morning I had called costumer service to insure that my husband and I had seats together since the website was giving me an error when choosing our seats and the representative mentioned our dog. I showed up early to the airport and when I got to the gate and we started boarding I was help back and told that I was supposed to have a yellow tag and that I should have checked in at the counter for them to give me that tag. I was not aware of this, the representative on the phone did not say anything. Nor did I see it anywhere in the checking process online, so if you travel with a pet and are not checking in luggage, just know that you still have to go to the check in counter when arriving at the airport unless you want to be the last one to board and not have room for your carry on in the overhead bins. Other than that, I had a great experience.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

We had a layover from YVR to Denver. We bought 4 bottles of Absolut Vodka at the YVR Duty Free for $116.20, after going through security and American Customs Pre Clearance at YVR, Vancouver. When we landed in Denver, United put us behind the American Customs as well as TSA again for some reason. We were forced to go through American Customs and TSA again. TSA confiscated our rightfully owned Duty Free Absolut Vodka bottles. Because United incorrectly forced our flight behind American border and TSA again, we missed the connecting flight. After United put us on a later flight, we eventually arrived in Chicago very late, with hardly any sleep. I am looking for compensation from United for our incorrectly confiscated Absolut Vodka bottles worth $116.20, as well as compensation for incorrectly putting us behind American Customs and TSA again, causing us to miss our connecting flight, making us arrive extremely late in Chicago.

From the first moment you interact with United Airlines, you can expect nothing less but extreme frustration. The baggage handler at the bag drop seems completely unbothered by the presence of customers waiting in line. No help was extended to load the baggage whatsoever. And if any of your bags is overweight by 0.01 pound they will make you re-distribute everything in your suitcase just to play power trip. When it was time to board no help was extended to customers to locate their seats. Moreover. It was a chaotic mess at the gate when it was unclear who should board first and everyone just bunched up, trying to get on the plane. I am sure the crew was doing their best to perform their jobs while being paid their wages however it shouldn’t be that hard to smile once or twice when you’re in the business if serving customers. It is a shame for the United States of America to have a flagship carrier of such low caliber. Our flight was also delayed by about an hour and a half due to further delays prior to our inbound flight. Being someone who has travelled for both business and leisure in Asia, Europe, and South America I have never experienced such poor quality of service.

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

The flight was canceled 3 hours after original take off time

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

The AA staff person who checked our bags was curt and almost rude. The FA also seemed unhappy doing her job. Overall it was like riding the school bus back in grade school.

Internet was a bit expensive and did not work ask that week otherwise a good flight

Ring in first class for an overnight flight, there was no blankets nor pillows for first class customers.

My Internet did not work for Outlook email or basically anything. I paid for one hour of in-flight usage and it was terrible. I spent a lot of time on different sites and browsers with no luck and a lot of frustration. Other than that, the flight was on time, crew was nice, service was fine. Seat was OK even though I paid for the extra 6 inches. I cannot imagine how tight the seats in the back must be.

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

Any flight to ORD after about 2pm this summer has been challenging. Flight was delayed getting in (coming from ORD) and that led to it not leaving before a ground stop due to lightening before they could fuel the plane, and so forth. They made up some time but we were still late in arriving at ORD, and that led to missed connections.

Food was ok, but not as good as I have had before on AA.

No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.

The flight was great; I don't see any area of improvement.

The crew were not very personable. The crew did not serve tea or coffee. The bathroom was not kept clean. Two out of the 5 toilets in the cabin weren't working.

Delayed first flight Geneva Madrid.. We didn’t miss our 2nd flight only because the 2nd flight Madrid Dallas was 1h delayed. However we did end up missing the 3rd leg Dallas Austin. Luggage didn’t show up in Dallas. So we re missing 2 suit cases. Customer service sent us to a hotel in Dallas. Only one room booked for 5!! Pretty bad experience overall. I won’t book a flight on Iberia in the future

Crew was excellent, great customer service, checked luggage took 1 hour and a half to come out at the baggage claim, the only negative thing about the flight.

Horrible experience airline crew was unprofessional. Flight was delayed. Suit cases did not arrive. Never flying iberia again

Iberia lost my bag, said they found it in another country, said they sent it to me, but never did. Went my whole trip without my stuff, but expecting it to show up because that’s what they said would happen. Their communication sucks, their website sucks, and to top it all off, their seats are small and uncomfortable. They’re bad at their jobs and they should feel bad about themselves. Do not even get me started on the flight home. AVOID!

The flight was delayed over 4 hours. Business class is just slightly upgraded economy.

Delayed and missed connections on leaving the states and returning Planes were old and small- very uncomfortable. Meals were good but very infrequent service for even water/drinks. No explanations for 3+ hour delay

Boarding on the buses isn’t efficient. Overall, it was great.

BEWARE!!! Iberia changes your seats at random. I paid for a window seat and they changed it to one in the middle aisle resting against the bathroom- can’t lean back + hear every flush. This on a 11 hour flight.. There were families that were broken up with separate seats all over the plane. Lots of upset passengers showing their seat confirmation to the besieged and helpless airline steward. Also, the gluten free meal was tasteless.

Boarding was efficient and quick, crew was very attentive, seats were comfortable.

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours

Very caring crew on board. Didn’t have dinner as I was sleeping. Was seating in the emergency row so I had comfortable leg room

Had a nice little suite although I couldn’t close the door (but I didn’t ask anyone to help). 5K is a nice seat and very private (you look in on first class). Enjoyable flight and nice crew.

There was a slight delay. Otherwise, everything else was satisfactory.

Although the crew were great and the good nice, I might as well have been on Ryanair for the amount of space I had. Not good enough BA. I’d rather pay more and not feel like a human sardine.

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

Love the A380 - loads of room. Headphone socket on my seat didn’t work. Sounds like a trivial issue? Well when flying long-haul the in-flight entertainment is what keeps you going so when it doesn’t work it’s a disaster. Pay attention to the details please BA. Spoiled what was otherwise an excellent flight with the usual brilliant crew.

Crew were fantastic can’t fault them at all. Couldn’t do enough for us

Crying baby the ENTIRE flight. Not your fault, but I paid 2700 for a premium economy ticket and it wasn't worth it. should have just stuck with coach. flight attendants very mediocre - minimal effort. Plane didn't seem very clean. Didn't have any cleansing wipes - most airlines give you this when you board. Flat screen scrolling didn't work. Toiletry case a joke - why bother at all?
