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.

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.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

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.

A three (3) hour flight should have meal service in First Class, not just potato chips!

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

Seats suck. Only one drink service in three hours with the flight attendants being more attendant to their phones than the customer. Painful in the extreme.

Extremely uncomfortable seats. Experience was like a Frontier Airlines flight. Would not fly it again.

Booked Economy but it translated to economy light for Lufthansa so now we are stuck paying an extra $75 per person both ways for our checked bags. If I had known that, I would have never booked these tickets because it came out to be more than other options. The booking in the kayak side clearly says Economy and has a link to the inormation for Lufthansa which states Economy included a checked bag. Super annoyed about that.

Flight was a little late. The crew was courteous, food ok

Very nice. Crew was excellent and our seats had great legroom which we paid extra for so I highly recommend this option when flying internationally.

Check in was great. Boarding seemed less organized. Flight was good.

They canceled our flight last minute and we had to get another flight with twice the cost

My flight was canceled. New flight is 40 hours later and I still didn’t get the flight from Frankfurt to Zagreb.

Meals were nice are abundant, the staff on both flights were personable and well trained

Budget airline feeling. Bad food, no drinks stingy to give even water

There was lengthy delay out of Pittsburgh but we still made it to Toronto with an hour until the connecting flight left. However, we sat on the tarmac for so long -with no explanation from the captain - that we had to run to make the next flight (a long distance). Luckily we made it, but it was only after we boarded that we got word that the flight was delayed due to the number of passengers who were delayed. If we had been told that information as we sat on the tarmac, it would have made a lot of upset and stressed out passengers feel so much better.
