I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

The flight attendants were rude. Seemed like they didn’t want to be there. Except for one girl that was really nice. Seats are sooooo uncomfortable. They give you a piece of paper and a thin cushion for a pillow and blanket that does nothing. Airlines have gone way downhill, especially United international flights. Food was disguting. Definitely flying ANA next time.

Crew and customer service were excellent. This flight also had plenty of leg room and seat mounted screens for entertainment. A very pleasant flight all around!

It would have been better if the crew has supported my husband's reasons for needing to keep the space clear around his feet, rather than insisting that he put his knapsack in that space.

Subject: Formal Complaint: Discriminatory and Unprofessional Conduct – Request for Immediate Action & Compensation Dear [Airline Customer Relations Team], I am writing to file a formal complaint regarding my recent travel experience with [Airline], which was by far the worst I have ever encountered. What occurred was not only unprofessional, but in several instances discriminatory, unsafe, and unacceptable. On the first leg of my trip, I arrived only four minutes past check-in. Instead of making any attempt to resolve the matter, your representative flatly denied me boarding and made me wait while she attended to passengers who arrived after me. By the time a manager intervened, it was too late to board, costing me time, money, and unnecessary frustration. The second leg of my trip (Chicago–San Francisco) raised even more serious concerns. From the outset, it was apparent that the staff—particularly two attendants—prioritized Caucasian passengers while dismissing African American and minority passengers. • When a Caucasian passenger in the exit row refused to comply with federal safety requirements, I, as a first responder, immediately offered to switch seats and assume the responsibility. My offer was blatantly ignored, and instead, a Caucasian passenger seated further up was chosen. This was discriminatory and deeply insulting, especially as I was actively de-escalating the situation that could have delayed the flight further. • During a lengthy tarmac delay of over 90 minutes, passengers were given conflicting and unreasonable instructions that created unnecessary distress and tension. • Throughout the flight, a visibly intoxicated passenger directly in front of me was disruptive, rude to others, failed to comply with seatbelt and electronic device rules, and yet faced no enforcement from the crew. In stark contrast, I was singled out for repeated compliance checks even though I was following every rule. This unequal treatment was so obvious that multiple passengers around me spoke up in my defense. This pattern of behavior demonstrated a clear lack of professionalism, disregard for passenger safety, and discriminatory treatment. I expect far better from an airline of your stature. As a paying customer subjected to this unacceptable treatment, I am formally requesting: 1. A full investigation into the conduct of the staff on both flights. 2. A written apology acknowledging the discriminatory and unprofessional behavior I endured. 3. Appropriate compensation for the distress, inconvenience, and mishandling of my travel. If this matter is not addressed promptly and thoroughly, I will have no choice but to escalate my complaint further, including filing with the U.S. Department of Transportation and sharing my experience through other channels. I trust [Airline] will take this complaint seriously and provide a timely resolution.

Check in was quick and easy during early hours. Flight was on time, and customer services was a plus.

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.

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

It was delayed instead of departing at 9:20pm, we departed at 11pm… putting us in Columbus after 2am! It was awful. Had I known about the delay, I could have spent some time in the United Lounge… I was starving because I started my journey in Budapest… so I was exhausted and hungry. Plus I had to make new arrangements to be picked up at the airport in Columbus, instead of midnight it was 2:30 am after getting luggage and out of airport. Not feasible. I would have just stayed in Chicago for the night and gotten a morning flight.

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

My wife and I love to travel, so we fly a lot. We've already logged 381,075 miles and with practically every major airline. But this flight was very disappointing. It started off well, with no delays and a new plane. But when lunchtime approached, all that good impression was ruined. Instead of white tablecloths, we were offered small, dark placemats, which, as it turned out, were perfectly adequate for the food. All the food offered—and my wife and I only took fish, and the meat—was not just bad, it was downright disgusting and not heated enough. The same applies to the appetizers. This was the first time in many years of traveling that we've been offered such disgusting food.

Lost luggage stuck no clothes and no word after 2 days leaving on cruise no stuff or clothes

3 hour weather delay followed by 1 hour (and counting) maintenance delay. UGH!

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

After a two hour delay, my flight was CANCELLED! No pilot available. Such BS.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

I wish American Airlines would change the airline industry by loading the plane back to front instead of front to back. Planes would board so much more smoothly and quickly.

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

Elderly female flight attendant was not customer friendly. There were only about 12 people on a regional jet that had about 60 seats. There were 8 exit row seats and none of them were taken. We attempted to sit in those seats and the flight attendant gave the standard " you didn't pay for those" so she would not allow us to move. What harm would that have caused ? They assigned seats to 5 of the 12 people in 2 rows, row 20 and 21. A simple friendly customer experience gesture of allowing us to sit in exit rows would have gone a long way in me having a very favorable impression on Air Canada. After that I have very poor impression of Air Canada and will not fly with them when I can avoid it.

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

Almost everything it was a “cool” ambiance but we arrived to Toronto so that it’s ok for me

The crew was really nice. The plane seats were kinda small even for a 5’6” / 158 lbs person.

Check in agent was very helpful and polite. He helped me board the earlier flight back home instead of waiting 2 hours at the airport for the next flight

extremely cramped seating... absolutely no leg room and when person in front of me reclined... I was pinned in my seat... absolutely ridiculous

Didn’t realize I purchased a basic fare with no carry ons allowed. Not very well communicated. Also had seats switched without knowledge and had to pay for different ones.

We loved our Air Canada experience and will definitely fly them again. It just so happened than in the first leg of our trip their entertainment system was not working, and neither was their oven so cold meal & snacks only.

Short flight. Everything was fine except the flight was delayed twice for a total of an hour.

I found the boarding easy and my seat was very comfortable as I had a lot of leg room. I am not too happy that I no longer have lounge access even though I used to get it with my TD credit card.
