Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

It was great. All the crew were professional and nice.

The flight I was supposed to be on was supposed to take off at 1:50 from State College. It was delayed over and over and over again until somehow I had to rebook on a flight that was supposed to have left State College at 8 am that morning but didn't end up taking off until almost 6 pm. Not only was this completely unacceptable, the "token from United" was a 15 dollar meal voucher that has to be used by today. I would personally like some miles added to my account for this inconvenience. I was in transit for 8 hours from the time I arrive at State College Aiport to when I got home. I was supposed to be home at 3 pm and I returned at 8 pm. Unacceptable. I have not been on an on Time united flight in nearly 5 years.

newer aircraft, ability to connect my headset via blue tooth for entertainment.

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

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.

Everything was good, except the seats in economy were so close together, you could barely get out when the seat in front of your was reclined. If the airlines keep jamming in more and more seats, it will become intolerable. I will look for another airline that considers customer comfort and does not keep adding more rows of seats for more profit.

Flight attendant moved my bag without notifying me and was rude to me when I asked him about it. There was no reason to move it.

Flight was on time, crew were excellent. For some reason our originally selected seats were changed. We had to re-choose our seats when we checked in online and options were limited. One of our two checked bags we placed on the wrong carousel. It was only be shear luck that I saw it. That cost us 20 minutes of wasted time. So much for the “priority” tags. They are meaningless, and have been ever since they were implemented. I wish you would do the save some money and stop using them.
