Not a fan of the diagonal partially enclosed business class seats or how they have to be converted to beds manually by crew. I prefer more isolation and user control for switching to lie flat.

Not a fan of the diagonal partially enclosed business class seats or how they have to be converted to beds manually by crew. I prefer more isolation and user control for switching to lie flat.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

There was a group of school age passengers that were very loud and unruly with their chaperones were no where to be found.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

I liked everything about the flight. The service was excellent!

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Delayed a day due to snow storm. Was upgraded. That kind of made up for significant delays from FLL to COS with no compensation or acknowledgement.

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

Missed the flight because of them and up geting a rental car

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

Do not eat the bagel! Otherwise, good albeit late, breakfast in first. Boarding downgrade only because flight was delayed due to plane change due to undisclosed problem with original aircraft. I did not use entertainment.

Was as expected. Good leg room on planes - much appreciated.

Fight crew was not very attentive and the bastions were gross!

Second time I took this flight, and they lost my luggage both times. Waiting for my suitcase now, last time it took two days to get it back.

Bordón could be bettet if the company say before boarding the order of the different groups.

There is no recline on flight from DFW to FRA. Middle eastern airways provide better recline option for the same class. FRA to Bangalore has better recline option. I bid 100$ for premium economy, my request was declined. But staff handled it without issues.

Another 35 min delay landing No apology no communication or acknowledgment about this

Try to humanize onboarding and take AI out. It's embarrassing and useless

I dropped my wallet under my seat on this flight with all of my money and credit card. I requested to be able to go back and retrieve it but Lufthansa denied my request. I went to the Customer Services and they called Lost and Found but I was told nothing found would be turned in until around 12:00pm. My next flight was leaving so I was unable to check to see if my wallet was turned in. I will never fly with Lufthansa again.

My concern is with Flight: 441 IAH-FRA I was very cramped in my seat and the person in front of me was reclined. I pulled my wallet out of my purse and when finished I did my best to cram it back into my purse. Our flight was very delayed and we were rebooked twice and lots of airport time. As I got off the flight I noticed that I had dropped my wallet( containing all my credit & debit bank cards + 240 US dollars & 240 Euros. I spoke to customer service & Lost &Found. I was denied access to look on the plane. Therefore I have been without money and given no help. Paula Bjork 503.545.6698

Overall good experience. Polite crew. Good foodandentertainment. Seats are small and bit congested though.

I ended up buying (for $340) "extra space" seats because I my flying partner was given a STY boarding pass, leading me to conclude that she was on standby and that we had to buy seats on the flight. I later learned that the flight was not sold out and that we could have gotten on as usual. To be honest, I felt swindled.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working.

- OK plane. Basic accommodations. OK food. The digital window shade wasn't working. - Expect to be woken up more than an hour before landing when they start dinging the bell and making announcements and turning on all cabin lights to serve a snack. I would prefer they remain quiet and only serve people who want to wake up.

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!

It was ok, not as good as it used to be. The Heathrow connection was a disaster - complete anarchy, unknowledgable and skimpy assistance and signage. Gate crew at next flight was great, held the flight while my wife struggled through security.

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona

The seats were tiny, being of a fairly petite build, I don’t usually expect to feel crammed and cramped in a seat, but I definitely was on this flight. I couldn’t even bend over to get anything out from under the seat in front and getting up to go to the bathroom at night with the seat backs reclined was nearly impossible. I had to do gymnastics to get over and out. For an airline that does long flights overnight, it’s kind of ridiculous.

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.
