Price gouged right at checkout

Price gouged right at checkout. Refreshed the price when moved to the checkout screen from $750 to $1000+. 25% increase is ridiculous, especially for a not-in-demand flight. Disappointing, especially considering they are not great in terms of customer satisfaction on flight either.

Extremely unprofessional customer service

Arrived at IAH with plenty of time, checked in through the premium line as a Star Alliance Gold member, and found the lounge closed with only a QR code for help. The first agent mocked me by telling me to “ask Delta if they’ll let you in” and then cut me off. The second agent, Danielle, told me I had “no right” to ask about alternatives, called me "greedy", “entitled,” "just looking to get something for free" and was openly rude and unprofessional. She even claimed she had no manager when I asked to escalate.The closed lounge wasn’t the problem—the way I was treated was. No notice, no alternatives, just two agents who were dismissive and insulting. United needs to address how their customer-facing staff are speaking to people. Secondary issue: people are loyal to star alliance so they can use the lounges. If yours is closed, provide an alternative (or at least professionalism about it).

Total disappointment with United Airlines – do not trust their promises

My United Airlines flight was delayed, which caused me to miss my connection. At the assistance desk, the United representative himself offered us two options: wait for an alternative flight only in the following days or take a train, assuring us we would receive a full refund.We chose the train, trusting their word.After weeks of waiting and several follow-ups, instead of the promised refund we received a $100 voucher to be used only on their website, valid for 12 months.This is unacceptable, especially considering that according to EU Regulation 261/2004 rules, in the case of a significant delay or cancellation passengers are entitled to a monetary refund, not a travel credit — unless they explicitly agree to it, which we never did.We lost time, money, and trust.Terrible experience, nonexistent customer service, and a complete lack of respect for passengers.Do not trust their promises: if something goes wrong, do not expect them to keep their word.We are still waiting for their response.

Waiting for a refund

I asked for a refund because the flight changed six (SIX) hours. After 55 days and 7 times by chat I hadn't had any refund still.

Our flight was on September 10th

Our flight was on September 10th. During the flight, we appreciated the service provided by the flight attendants.However, we had several complications with our booking. Due to bad weather, we missed our original flight (tokyo to new chitose). We checked with other airlines, but there was no other way to get to our destination, Chitose Airport. Thankfully, United informed us by email and on their app that they had rebooked us on a new flight (3 days later).When we arrived at the airport on September 14th, we were told we weren’t registered on any flight. We showed the staff the confirmation email and the booking shown in the United app, but they said we still didn’t appear in their system. After some discussion, they eventually let us go through and wait on standby for the day.It was a terrible experience, and we’re not sure if we can trust United in the future.

✈️ United Airlines failure when it matters most

✈️ United Airlines – A Failure When It Mattered Most ✈️This weekend was one of the most important milestones in our lives—taking our daughter to college for her freshman year. We trusted United Airlines, even flying First Class as a Premier Silver cardmember, expecting reliability and care.Instead, out of four checked bags, only one arrived. My husband was stuck at the airport late into the night trying to get answers, while our daughter began this new chapter of her life without her belongings.This wasn’t just an inconvenience—it was heartbreaking and unnecessary stress during a moment that should have been joyful.United, families deserve better. Your loyal customers deserve better. Do better.#UnitedAirlines #CustomerServiceFail #DoBetterUnited

Stranded by United Airlines

Stranded by United Airlines — and They Couldn't Care Less 💬We arrived late into Denver due to a United delay, leaving just minutes to catch our connection. We sprinted down the concourse — exhausted but hopeful — only to find the gate still occupied and the plane still there. No attendant in sight.When one finally appeared, we said, “We’re here!”Her response? “We waited long enough. The door is closed.”And that was it. No effort. No empathy. Just a generic card and “call customer service.”Then things got worse.🛄 At baggage claim — no bags. Turns out United managed to get our luggage on the flight, even though they refused to let us board.No more flights that night. We were left stranded in Denver with:No bagsNo supportAnd no way to reach our destinationWe paid out of pocket for hotel, meals, and essentials.When we contacted United’s Customer Service to request reimbursement for these unexpected expenses?Their response: “It was a weather delay. We owe you nothing.”Even though they shut us out, sent our luggage without us, and abandoned us with no recourse.🛑 This isn’t just about a missed flight — it’s about a total lack of accountability and basic human decency. United had every opportunity to make things right — and chose not to.Passengers deserve better.

Frustrating Experience with United Airlines Flight Cancellation and Poor Customer Support

We had a direct flight booked from Dulles to Heathrow that was delayed several times for weather-related reasons. While I understand and respect the importance of safety, the flight was ultimately canceled in the middle of the night—not due to weather, but because there was no available pilot.What followed was a disorganized and incredibly frustrating experience. There was almost no communication from United staff, and those who were present were largely unresponsive and unhelpful. We waited in a line for hours that barely moved, with no clear direction on how or when we would be rebooked.To make matters worse, the United app was extremely laggy and failed to show all the available rebooking options. It was only after being on hold for two hours that we finally reached someone by phone who was able to offer us better rebooking choices than what the app had shown. If United expects customers to manage rebookings on their own, they need to provide the infrastructure to do so—starting with a functional app and timely, accurate information.Unexpected issues happen, but the lack of support and communication made an already stressful situation far worse. United needs to significantly improve how it handles flight disruptions and how it supports passengers when things go wrong.

I have never had a more shit experience the with united. I had to get book a ticket and it said on the ticket and the app that it left for that day at 1 a clock so I got through security and wait for the boarding to start and only as I scand my ticket did they say somehow they booked me a already booked seat and they couldn't let me on the flit. so I was destraught because they couldn't get me to Missouri for 18 hours which meant I had to miss all of the preperation of my brothers wedding so I'm crying so they say "we can get you confertable in are top launge and we will pay you back" it as been 2 weeks I spent 300 because they said they pay me back and I got nothing. I'm never flying united again and bless the souls of the people who do.

Inexcusable Treatment of terminally ill passenger on Flight UA 96 – July 16, 2025

My father is terminally ill with pancreatic cancer. We had just completed a critical medical procedure in California and were returning home to Australia under extremely fragile circumstances. My elderly parents had thoughtfully and generously purchased a business class upgrade for me to help me recover and better support them throughout the long-haul flight. I was issued a boarding pass for Seat 9A, boarded the aircraft, and was seated.To my shock, I was abruptly asked to disembark the aircraft due to what was described as a “payment issue.” I complied immediately, assuming this would be resolved quickly and respectfully. Instead, I was made to wait outside the plane for over ten minutes, during which time my frail, cancer-stricken father and elderly mother were left standing outside the aircraft, confused and distressed.A rude and dismissive United supervisor at the gate then informed me that I had to return to my original seat in premium economy, despite having paid for the upgrade and already been seated in business class. When I calmly explained that the upgrade had been paid for and confirmed, I was met with hostility, no explanation, and no effort to resolve the issue.Meanwhile, my parents were explicitly threatened with being removed from the flight entirely if they continued to advocate for me or question what was happening. This behavior was not only unnecessary — it was cruel. They were already under immense emotional and physical stress. To threaten two elderly passengers, one of them gravely ill and visibly unwell, is shocking and utterly indefensible.When I was finally permitted to re-board, I witnessed the devastating emotional toll this experience had taken on my parents. My father was physically shaking, and my mother was so horrified and traumatized by the way we were spoken to that she refused to eat for the entire flight.To add insult to injury, it was clear that my paid seat had been given away to a man who boarded after takeoff and did not pay for the upgrade. The way this was handled was not only unprofessional but inhumane.This entire episode was deeply humiliating, emotionally harmful, and completely unacceptable, particularly given the extreme medical and emotional stress we were already under. The lack of empathy, decency, and professionalism from your staff is something I will never forget.
