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.

Seats are uncomfortable and my impressive barely 5’10” frame meant my knees were touching the seat in front of me. My 5’3” sweetheart found the seats equally uncomfortable The crew were transactional. The food edible. The entertainment manageable. The boarding process efficient. The experience okay.

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

Our gate was changed several times, and the gate agents were just as in the dark as all of us in knowing when our plane would arrive at PHL.

mechanical problem delayed more than 2 hours on the run way.

The boarding process was slow and we had a delay on the tarmac, not the fault of the airline. They had ZERO food options available for purchase which shouldn't happen.

Plane was delayed for 3 hours, due to situation within aa control. Information was shared poorly. We sat on tarmac for over 40 minutes after the 3 hour delay.

American notified via app that the flight was delayed. However, when I went to the gate, they were already boarding and had not updated communications that they had pulled the flight time back. They made the entire flight re-check in which by this time I had lost my exit row seat and ended up in a middle seat. As a 4 decade flyer of American and Exec Plat, my expectations for the company are that the customer service would be better. This unfortunately is no longer a strong point for any of the major airlines including American. They are basically city buses flying at 30 thousand feet.

Horrible, they detoured my first flight to Roswell and the communication on why was very poor, We arrive late then waited 20 minutes for them to set up the bridge. I arrived at my connecting flight gate and was told my seat had been given to someone else even though the flight was delayed. We then get to customer service and the computer went down for several hours. The person at the counter was eating their lunch while trying to help me get a flight. Dhe then rebooked on a flight with a connection that was leaving two hours prior to me landing. So I had to then stand in another line to get rebooked. I missed my trip to Morroco and waited 7 days to finally get my luggage. It was a nightmare.

We were bumped out of bulkhead seats we purchased a year ago. We were moved to row 5 and the folks in row 4 fully reclined making it difficult to get out to use the restroom. The seat have too little padding making them uncomfortable 3 hours into the flight. The movies did not offer closed captioning and the earbuds were poor so the entertainment was mostly unusable. The food was just passable. I would not fly Iberia/level again. Iberia also bumped us off our direct return flight so I would say the whole experience with this airline is poor.

The flight was operated by level, who had a sister’s check in procedure (2 hours) due to understaffing and a computer malfunction. While 3 agents stood at the business check in, with a total of maybe one actual customer there at a time, a huge line formed at economy check in with only 1 agent staffing the check in. Then, my luggage was lost - a guitar case with contents inside valued at 3,000 USD. The computer system of LEVEL could not locate my bag and had no record of it, and IBERIA (with whom I purchased my ticket and the checked bag) refused to help. It was a disastrous experience and I will never book Iberia again

I liked the comfort of the plane. It was unexpected from past experiences.

Chair is very high. Your feet cannot touch the ground for 8 hours flight. It was a nightmare. Food was bad.

Flight was delayed 3 hours and 15 minutes. The delay caused me to miss my tour group due to arriving late.

Flight boarded three hours late for no reason other than someone made a huge error in crew scheduling. We missed our connecting flight in Madrid and got zero help from American or Iberian airlines on rebooking. We had to pay for a car to take us to the Madrid train station and pay for train tickets to Santiago. We never used our booked flight to Santiago. American claims I can submit the expenses but they are not obligated to cover them. Very frustrating.

Super uncomfortable main cabin. Omg no leg space or seat space horrible

The trays weren’t wiped. They still had food from last passengers

Flight reservation was canceled withou notice had to spend the night in the airport

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.

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

The transatlantic leg was on Discover Airlines. I’m 6’2” and the extra leg room seat was acceptable, the seat it self was moderately comfortable (slightly softer than a church pew). The food was a standard economy fare. Frankfurt to Prague leg was on Lufthansa the business class was as advertised 10 across the board.

Recent movies and music availability like it used to be

Great until k found out they never got my check bags onto the plane.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

The flight was ok. The seats are so small. The free wifi for members was not an option on this flight. The one flight attendant, older woman with straight white/grey hair, was very rude. The gentleman next to me asked about the wifi since he was a member as well. He stated, accurately, that the option to enter the idea number was not available. Her response was, "I don't know what to tell you" and walked away from him. The rest of the staff was wonderful. I asked another flight attendant about the wifi, she said the free wifi was not enabled on that flight (true or not- at least she was friendly). It was also pretty dirty. When I opened the tray table it had mushed crumbs and there was a dirty used pair of ear buds in my seat pocket. Lastly the air vent above my head was working but stuck so I was unable to move it to face me when it got warm. I fly American often but this really was not a great flight.

Someone switched seats in business class so they could sit together and we were left apart (3). Very disappointing. Staff did nothing

I have always been pleased with their service. Would not change a thing

Three major things that led to my low rating, 1. Internet wasn't available for the whole time, and 2. TV became available way into flight, after numerous system reboots, and 3. Food is not good at all.

Did not use entertainment Food great Stewards had an attitude, not the best but below average from my other flights with AA or BA

They removed our booking without telling us. Cost us thousands to book last minute

My flight was late. We stayed in aircraft one hour 😩

I was disappointed with the quality of the food and the fact that I was not given a toiletry bag for an overnight international flight
