Flight was delayed 14 hours! We missed an entire day of our vacation and had to pay for hotel that we didn’t use

Glad they offer free meal, & I got a complimentary drink I’d like coffee,tea, or water offered 3/4 into trip

Could not check in online. Called airline twice, thinking Hawaiian Airlines could check me in during phone call. NO. In 2nd phone call, Customer Service explained that due to “transition period” of Hawaiian Airlines/Alaska Airlines merger, I could only check in at the airport. In addition, flight to Kahului was late at arrival gate; I made connection to Lihue but my bag did not, so I had to return to Lihue airport a couple hours after my arrival to retrieve the bag.

The boarding was confusing because the PA system at PDX was so quiet you couldn’t hear anything being said . The seats were uncomfortable. The food was pretty bad and I normally don’t mind airplane food. The flight attendants were not friendly. I learned upon check in that Hawaiian airlines had reassigned our seats of the second leg of the trip. I had confirmed and paid for special seats but they put me and my companion on standard seats in different rows. Hawaiian also did the same on my return flight after the flight times had changed. I happened to go online to check my reservation and saw the flight had changed. I gad received no notice. I saw that my confirmed seats that I had paid extra were gone. After much back and forth with the airlines they refused to correct their error. I showed them confirmation documents of my seat reservation and receipt of payment but they refused to correct the seat change or reimburse me. I had to pay $200 again to reserve the original seats. Shameful and manipulative. They basically held me hostage. If I wanted to be in that flight I had to pay up.

I liked that internet connection while in flight was available.👍

My experience from Lihue Airport was the “Flight Experience from Hell!” First, I was pulled aside by the Lihue TSA and searched thoroughly! Not once, but twice I was molested by 5 different TSA agents using some sort of smear cloth testing to see if I had been exposed to something dangerous! I can’t tell you what because they never gave me an explanation by the end of a near delaying incident of boarding my plane. More importantly, I was generously provided an airport wheel chair and personal porter because of my health condition. TSA even took your wheelchair apart! What’s up with that? I’m near 75, caucasian, never been arrested for anything, don’t do drugs or alcohol, and patiently and politely abided to their instructions for a full damn 20 minutes! Awful and humiliating experience especially when two different agents literally groped my testicles and crack of my butt! Then they lost the cap to my inhaler. When I got to my destination, a whole bottle of prescribed pills were emptied because of them not tightening the cap back on! Total BS and unprofessional by the lot of them! The short flight to my connecting flight to the mainland on Maui fortunately was uneventful. However the Hawaiian aircraft to San Jose was one of the worst flights I’ve ever experienced without crashing. I believe it was a 330 Neo. May I ask, why did you put three more rows of seats in the damn plane since I last flew on a Hawaiian aircraft? I had absolutely NO legroom compared to the last time I flew with you. And I’ve done a few Hawaii/mainland trips, even a RT to New Zealand before. Then, the icing on the cake was a couple with a one year old baby that literally cried and screamed for all but 15 minutes of the 5 hour flight to San Jose! Further, I couldn’t move my seat back even a millimeter because a car seat was placed from their window seat to the back of my seat! My Hawaiian flight was a freaking nightmare and fortunately will be flying back to Lihue direct with Alaska!

The pilot performed the smoothest landing I’ve ever experienced. What a light touch. And I’m an avid traveler!

Mid flight we were bothered by a bee. Kind of odd, but a bee allergy made it a bit stressful. Attendants passed by our aisle during service multiple times. Otherwise, it was fine.

Terrible. Would never fly again. Took them several hours to prepare the plane and and reached my destination 4 hours late.

Our boarding was delayed due to two flat tires, but I appreciate the focus on safety. I also appreciated the additional offerings for drinks which never happened before except on Hawaiian Airlines. The hospitality is fantastic! Glad I upgraded to premium seats for the extra leg room as I was getting frustrated when the person in front of me was very restless and kept shifting. Otherwise, it was a fantastic experience.

After boarding the plane in Chicago, the passengers were told that there was a technical problem with the plane. Passengers remained on the plane as they tried to fix the problem. After what was probably an hour passengers were told that there was a need to change planes as the problem was not solved. Passengers disembarked and boarded another plane. After taxing to the runway and waiting for takeoff, passengers were told that owing to the thunderstorm the flight was unable to take off but would try and reroute. After some time passengers were told there wasn't enough fuel for the new route and the plane had to return to the gate for additional fuel. after another log delay the flight got underway. On the plane there was food, drinks, ice or entertainment. We were a glass of water, which appeared rationed. Flight arrived about 5 hours late. The pilot was fantastic and communicated with the passengers throughout the ordeal.

The flight attendants were great, I joked with one I can’t remember her name, a blond, really sweet. I thought it was run well very professional. This was great i survived Spirit, I know for which I speak.

My husband and I recently had an unfortunate experience with Lufthansa. At the Philadelphia International airport, the ground staff refused to board us because we didn’t have a current visa stamped on our passports for Frankfurt. We completely understand that this was our mistake. we should have double-checked the visa requirements before our trip. However, the issue that upset us most was how the situation was handled by the staff. They told us they would mark it as “boarding denied due to visa issue”, but instead they recorded it as “no show”. Because of that incorrect entry, our return flight was automatically cancelled as well, which caused additional stress and expense. Mistakes can happen, but we expected more transparency and accuracy from a reputed airline like Lufthansa. It would have made a big difference if the staff had been more careful and considerate in documenting the situation correctly.

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

The worst landing I have ever had on a domestic flight. Thought we would lose the landing gear on landing in Newark. Then we spent 40 minutes trying to position the plane in the right place to be able to get the jet way to the plane. The plane arrived stopped. The announcer was that we were there. Everybody got up, then we were told to sit back down because they had to have us towed to a different position. We got towed and then everyone stood up and they told us we were in the wrong position to sit back down again, and then we got towed to a different position This did not happen immediately. It was 30 minutes while we wandered around a small section of the tarmac in Newark close to the gate, but apparently not close enough. Horrifying experience The CAB should be investigating that flight

Boarding was organized. Plane seats comfortable and service was attentive. Food options were good.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Excellent - explanations were clear staff was nice and flight was comfortable

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

Did not get the seat I selected and paid for.

Plane was delayed for 6 hours, at first by weather, which is understandable, but was further delayed with NO given reason for 2 1/2 hours more. We had no clue when we were going to depart actually until they opened the ramp. VERY POOR to ZERO COMMUNICATION!!!

Flight was delayed and after being in the airport for like seven hours, it was canceled.

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.

Overall very good, only complaint I have is the crew from CLT to SAT could have collected trash sooner.

Above and beyond effort from this crew in a tough situation. So helpful and understanding. Thank you!
