The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Beijing PEK to SFO. I had an economy seat on this flight. The seat comfort was acceptable. My main complaint is with the FA’s lack of personality and absence from servicing the plane, specifically restroom care (I wish I could share a pic of the restroom that I captured) and care of travelers—drink cart/availability of drinks. I'm amazed at the level of service on other International travel where a passenger is most often appreciated.

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

I feel bad, but Swiss airlines is not an airlines I will ever fly again. Their cabins are basic, seats are extremely uncomfortable, crew is a hit or a miss with service. What's worse is how they make you feel they are there to make money and not make your travel needs be met or make your travel a pleasure. They charge for 2nd bags, seat selection and felt like a budget arinines frontier/spirit airline attitude and approach. Their business class is from the early 2000s, basic. Additionally, planes going to India, are old, falling apart and not maintained. Even the crew mentioned this is typical of the airline having older planes going to India. Panels detached and loose or stuck with duct tape, seats scruffed up and dirty, seatbelts roughed up. The scariest thing was when I saw a window panel next to where I was sitting loose and dangling. The crew mentioned it's only cosmetic and assured the integrity of the plane was inspected by the maintenance crew. This is where they confessed about planes going to India being old. I UNFORTUNATELY would NOT recommend Swiss airlines to anyone and will NEVER fly with them again!

The ANA crew and their members were all extremely nice and caring. Shout out to the crews for working on Christmas and New Years. Y'all the real MVP

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Boarding always seems a bit chaotic. Seat spacing could leave more for leg room.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗
