Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

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.

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.

It was a late flight; crew was invisible. Zero air flow - the tiny plane was a sauna; the left the lights on for 1/2 of the flight; there was no water. Never again.

What an amazing plane! We flew a 787 to Miami. Although the Internet was not functioning, it was a wonderful flight.

Plane was in good shape, multiple passes from the drink cart, and one of the smoothest flights I've had in a while.

After lack of help in Philadelpha made us late to board our flight to akansas City, our flight to Kansas City was very good. And the flight attendants were also very good. The only thing that sucked was problems with assistance in Philadelphia caused our bags not to arrive.

Legroom was decent, but the seat comfort was horrible; I believe the seat cushions have lost their cushion. I was uncomfortable and had back pain throughout the nearly five-hour flight. WiFi did not work despite my attempts to get it up and running. This was very frustrating as passengers all around me were streaming football games, movies, and accessing email and text messages. One flight attendant suggested it was my seat, but that makes no sense, given WiFi doesn't work that way. On another note, I rarely have a good experience with aainflight.com.

Id like for them to not have lost my bag. And maybe be a little nicer to me, given the fact they lost my bag.

Hey as long as you bring me back to earth in one piece I’m good! Otherwise great flight smooth take off and landing good staff Only thing is the staff at the back of the aircraft chatters a lot it’s annoying at times but I’ll let that go because they are very sweet overall.

The airline company should manage their crew for the plane on better schedule so people don’t have to wait in the plane. And this flight that I had had no snacks offered, and if you would like a water, you had to come see somebody and ask for. If airline would let people know that they are no longer providing or offering any food. At least people could bring their own if they wish.

On time departure was much appreciated. However, as a frequent flyer and American Advantage member, I was as disappointed not to get an aisle seat.

Flight was cancelled due to a myriad of operational issues. You guys really suck
