    Ice cream sundae
    Sam O.

    Denver to Honolulu was great! Old 777-200 so old first class seats but they were clean and comfortable. Airplane was like a freezer at first but gradually warmed up. United's really improved catering. Had the preorder Denver special bison meatloaf. Decent portion and filling! Love the ice cream sundae for dessert! Didn't try the pre-arrival meal, but it was a Kalua pork sandwich, pasta, or a green goddess chicken salad. Our flight attendant, Peri, was amazing!! So attentive, always refilling drinks, etc. and super kind!

    I had a great experience flying with United Airlines coming from LAX to Denver airport. I also have a return flight to LAX and hope it doesn't get cancelled due or delay due to the coming storm. The United terminal here at Denver airport is big, I think it's one of their hub. It's also more updated because the Gate sign on the ceiling also shows the destination city on it. The plane was fine to me and the entertainment system seem to be upgraded because it supports Bluetooth so I was able to use my Samsung Galaxy buds earphone. The only issue I had was that it took forever to get my carry on bag at the carousel and I couldn't prepay for my checked bag in advance through the mobile app so I had to use a computer.

    I used to flight United 2 decades ago for years...out of Seattle and they were wonderful. Denver team are nice and friendly. Since I only do carry on..can't say much on their new policy. Seats are definitely smaller (or I'm getting wider). Foods are okey, I tended to skip it most of the time. Only take it if sounds interesting. But for some reason for 4 flights from/to US to Euro, the flight attendants are lack of friendliness with fake smiles. But over all, not bad.

    20 minutes sitting at the gate to find someone who can open the door

    I'm generally sympathetic w United, but when you can't open the doors, it is time to use the emergency exit... 30 minutes waiting for someone to open the door is inexcusable

    Layover between Ontario, California and Colorado Springs, Colorado in Denver... Even though the flight was at 5am and I had to be at the airport at 3am, I was alright. I got to my destinations on time; my luggage wasn't lost; and the personnel were courteous and efficient! My seats were assigned to me, and they were satisfactory. The flights were short enough to not need to use the restroom. The only downside was that I would be charged for a carry-on bag. I stuffed everything into my check-in luggage before I got to the airport. I still had to pay $40 for my check-in bag - which I paid online since United Airlines texted me a few times to check-in for the flight. I also received texts to update me on the gate change and that the flight was on time. Overall, it was an uneventful experience. I didn't get to select my seat, but I'm glad that the seats are assigned!

    Denver is one or the United hubs and a fairly frequent stop and grudging layover for me. Who like connections anyway! The travel gods were kind to me on this trip and the flights were all on time. I find their service consistent and good.

Yesterday, April 4, 2026 I originally had a flight to Houston at 11:30AM. Houston was the layover to my final destination of Atlanta. At 10AM I was told that the first flight was delayed an hour which was going to cause me to miss the second flight. Myself and two other people approached the gate to resolve the issue and was told that the only option is a direct flight to Atlanta that doesn't leave until 10PM. I was immediately irritated because I had been there since 8AM and 10PM is a long time to wait. I respectfully asked if they could ask the flight in Houston to just hold off since we would be getting there late by 2 minutes. The very rude woman at the desk replied "if it was more of you but it's just 3 of you." So the three of us don't matter? Obviously what I'm asking can be done, but because it's 3 of us we don't have the option to try to make our flight that was inconvenienced because of your company! Truly disgusting. I was told my other option was to take the flight and "see if they can help you." While I understand that things happen out of employee's control, the attitude and the lack of empathy is what made the situation worse. However, that was not even the worst of it all. I sat in the airport a total of 12 hours just to get banned from boarding my flight. I came with a backpack that I always take with me, that fits under the seat, a personal item. I did not have a purse or anything else. The backpack was all I had, but being at the airport so long I had purchased a charger, water and food so I was carrying that plastic bag with my personal item as we were boarding. I was told to step aside to speak to someone about my bag. Not at the counter, or outside of the boarding area, I was standing at the entrance of the boarding area. After standing there several minutes and no one approached me I thought maybe she wasn't talking to me. After all, I have never had a problem with this bag. I start walking towards the ramp and a lady asked me to come back. I explained to her what I just explained to you and she said that my plastic bag of food counts as my personal item so I have to pay $99 for my backpack. I'm flustered because I fly allllll the time and everytime I'm in the airport I get water and snacks and take them with me. Not one person on 100s of trips have ever approached me about that bag! The lady already told me I had to pay, but continues to make me weigh it. As I'm weighing it, it now doesn't fit because I put the bag of snacks there. After she yelled for the 10th time "it's $99!" I said, fine, here is my card!! After I said that she says, "you're being loud and disrespectful so I'm not letting you on!" I never once raised my voice or was rude. She thought I didn't have any money and when I did she created another problem. I pleaded with her to let me on because I had been at the airport 12 hours and I needed to get home to my children! She wouldn't even look up from her phone. I pulled out my phone to text my babysitter that I might not be coming home and she goes "I was about to let you on but you're secretly recording me!" I picked up my phone IMMEDIATELY to show her my text thread and she continued to tell them to close the door.

I understand stuff happens but come on.. everytime i fly in and out to Denver there's something. Since they changed their business model and became like the other main airlines...like no more free bags or open seating, their service has gone downhill. Almost every gate agent now asks for voluntary checked bags as they claim overhead bins are full. As I had a layover iMCO I was like ok I'll do it. I thought I was doing a good thing. I even asked the gate agent is there anything I need to do because I have a layover? No he says... it will meet you at BWI. The one time I dont put my apple tag is when they lose my luggage!! I arrive at BWI... it's 1 am. And everyone else got their bag except me.... They track my bag it's at MCO. My bag tag apparently fell off. The airport code tag fell off. Not cool. It took a day and a half to be reunited with my bag. However SW customer service agents over the phone were great. My bag was placed on the next flight out and they used like a courier company to deliver my bag to my house I did have the option to pick it u at the airport but it's too far. I 100% place blame on the baggage handlers at DEN. If you are voluntary doing a checked bag make sure you take pictures of your luggage, make sure the tags are secured and throw in an air tag. SW should limit the amount of carry-ons if they constantly need people to have their bag checked or lower their prices. SW did look out for me and issue a voucher for the inconvenience.

    For decades, Southwest Airlines stood out as one of America's best-run airlines. Its success was…read morebuilt on a simple formula: low fares, friendly service, operational excellence, and a genuine focus on the customer. This strategy created remarkable loyalty and made Southwest one of the most admired and fun airlines in the industry. Today, the company appears to be moving in a very different direction. Following pressure from activist investors and changes in leadership with the CFO being promoted to the CEO, Southwest has embraced a more revenue-driven strategy focused on increasing shareholder returns. The introduction of checked-bag fees, paid seat selection, and other ancillary charges marks a significant departure from the business model that differentiated the airline for more than 50 years. Today, checking a bag can cost around $90 on some fares, and passengers often have to pay extra to secure a desirable seat. Without doing so, many will end up in a middle seat toward the back of the aircraft. I did on all my flights to SLC via Denver and Los Angeles. These initiatives may improve short-term cash flow and earnings, but they also risk weakening the customer loyalty that was once Southwest's greatest competitive advantage. In my case, i will avoid Southwest like the plague and i really fly a great deal. Over the past couple of years flights are systematically delayed, luggages are lost , agents at the gate have little authority to change things as the focus has shifted away from customers and operations. Profitability and shareholder value are essential goals for any public company. However, the strongest businesses create long-term shareholder value by first creating exceptional value for their customers. Time will tell whether Southwest's new strategy proves successful, but from a passenger's perspective, the airline has lost much of what once made it special.

Had gotten there extra early, even though the TSA website indicated short wait times at DIA. Boarding was easy. Sank into my seat and ordered tonic water to stave off leg cramps. The ONLY annoying aspect of this trip was the constant interruption of announcements, perhaps ten before takeoff. Flight attendant was masked. I read lips. I didn't note my lack of perfect hearing on my account, because I don't like people shouting at me. The mask made things slightly more difficult, but we communicated by her pointing at things and me speaking. It was fine. Lunch--cold salmon salad--was delicious. The wine was a generous pour, and I was able to sleep. Which was the desired outcome. I was exhausted. Entertainment selection, again, was okay. I didn't find any movies that I wanted to see, so watched SVU instead. The flight took off on time, and landed on time, too.

I arrived at Heathrow hours early as I shared a cab with a coworker and his flight was much earlier. I could not check in on the app or on the website in the day prior, so I stood in line for close to an hour at the American window where they told me I was actually flying BA (my travel record showed American) and I needed to go to another terminal. I got to that terminal and tried to get in line to check in but BA employee said I needed to use the kiosk. I explained I was unable to check in on apps or online and needed an agent. They insisted I try the kiosk first. Unsurprisingly.. it didn't work. I was allowed to get in the check in line with an agent where I stood for the next almost 2 hours. Yes, 2 hours standing on a concrete floor. My back was screaming (old people problems, I know). I finally got up to an agent who said I wasn't able to check in because I needed to show my visa. I pulled up my British electronic visa and she said "no love, your American visa".. while holding my American passport in her hand. I explained I don't need a visa because I am an American returning to my home country. She looked confused but decided she needed to call someone to help. I stood while she was on hold and transferred around to different places who eventually told her it was an issue in the system today and they would remove the error. She then told me I had no seat on the flight because it was oversold and they couldn't guarantee I would get on, so they may have to book my on the next flight which was the next day or would need to look at another airline for me. She gave me a boarding pass that was or standby and said to hurry to the gate to try and get a seat. I got in the security line and about 15 minutes later, I was up.. I scanned my boarding pass and it errored out, not letting me through. An employee told me I had to get in a different line to see what was wrong with my boarding pass. I stood in anther line for a good 40 minutes. Once I got help, they told me I couldn't get through because I don't have a seat and would have to fly standby. I explained, yes.. that's why I have a standby boarding pass. It says standby on it. She said it wasn't standby in the system and it needed to be fixed, so she had to call someone to assist. Another 15 minutes later and they couldn't get it to work and I was going to miss the flight, she said she would take me through a different security line so I could get to the gate. She did that and I had to take a train to get to the gate, which wasn't working for about 5 minutes because it was having a "security sweep" with officers and dogs going through it. I finally got on the train, got off at the right place, ran all the way to the gate as they were boarding. Asked if they had a seat for me, and they huffily said they did but I almost didn't because I waited so long to get to the gate. Are you kidding me? I got on the plane and will be happy to never fly British Airlines again. I guess all the great luck I've had traveling was made up for on this trip. Just terrible.
