The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

The flight was delayed so the people from a late connecting flight was able to still make the connection.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

Ridiculously slow disorganized boarding, ended up 35 min late and people missed connections

The Cree was BEYOND AMAZING. They were, by far, THE BEST CREW I had the pleasure of flying with. They catered to my every need, beyond friendly, and upheld the highest level of professionalism that is of Lufthansa Airlines.

Really solid flight! The in-flight entertainment screens are not very touch-responsive in the way that of other airlines’ are, which was my only issue. But otherwise we had good food and drink offerings and the flight attendants were very welcoming.

The Frankfurt airport is just not that easy to get around. Having to get from one end of the airport to the other when it was not well marked was a challenge. The flight itself was fine. I would fly with United again.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

Boarded over an hour late, no communication, the sign just changed, no attendant to answer questions - she disappeared forever (hiding). Small plane and couldn’t hear the overhead nor understand.

Service in first class no longer exists on American Airlines .

Customer service in first class does not exist on American Airlines

I never have a good experience with American and this was no different. The airplane was INCREDIBLY hot. Like unbearably so. Everyone was fanning themselves with pamphlets and sweating. When someone asked the flight attendant to turn down the temperature they were told there was nothing the crew could do. Once we pushed back from the gate we then had to wait an hour to take off and the communication from the crew was not good. People were getting up this whole time and a man was even in the bathroom when we took off. Once we landed at our destination we waited another 30 minutes at the gate to deplane with, again, no communication from the crew as to what was going on.

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.

First, to be fair, the flight was on time and the trip through the air was relatively smooth. But the flight was full, and they were checking carryons. As this process went on, the crew got increasingly rude and overbearing. During the drink service, a young girl (maybe 9) who had gotten up to use the lavatory got stuck behind the cart. At some point, she started feeling fearful and overwhelmed. Passengers noticed this and asked the crew to let her return to her seat. They refused. Then she started crying, and they still refused to move the cart forward to let her sit. The poor girl was trying to be brave and compose herself. The crew handled the situation terribly and with zero grace or decency. That episode, to me, encapsulates AA’s attitude toward its passengers. Disgraceful. The plane itself was cramped and miserable, as usual. There was zero inflight media or entertainment, other than the lane and borderline inappropriate jokes the steward made during the safety briefing. Then, of course, it took the better part of an hour for the checked bags to show up at the carousel. AA is no better than the el cheapo airlines these days and a far, far cry from its former self.

First class flight attendant was rude and lacked any customer service skills.

Customer service for American Airlines first class is at an all time low.

Paid for a window and was assigned to a middle seat with 2 very large people on each side of me. Flight was sold out and I feel I need to be refunded foe paying for a window seat and being put in a middle one..

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

Happy and nice crew and the atmosphere is very easy and calm. I got a wonderful travel with UA this time

Seat cushioning, and having at least 1 checked bag free, I dont understand why international flight would not include a checked bag.

If I book through Lufthansa, I expect to fly on Lufthansa, not discover. Food was bad, plane was delayed. Will not be flying Lufthansa again.

Food service was good. Aircraft was old and needed upgrade such as seats. Flight was delayed about 1 hour.

The only thing that the airport can improve which will help Lufthansa from delay flights is to warn the passengers that are flying to the USA to be earlier to the gate due to the documents check that in our case delayed the flight

Disappointing. Too many let-downs, in delays and communication, by both Lufthansa and Discover to put in an email. I am resigned to the fact that this is what I should expect from all airlines. Unfortunately.

Boarding was total chaos. They didn’t know what they were doing and taking bus to the airplane is like going back in time. The food is bad, portions are very small and we don’t get simple paper napkins! Is it really that bad?

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.

Business class area too small and chair and equipment not comfortable .

Lost my luggage in London Was double charged for luggage

Boarding could have been better organized. The one member of staff disappeared for a while so boarding by group relied on honesty.

I never made this flight but the staff helped to get me rebooked (see previous review)

No land services during boarding, specially while moving from terminal to another

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.

Flights delayed, and not communicated to the level I accustomed to by other airlines. The crew seems to be hating their job and it shows. It costs you nothing to smile and be a bit more friendlier. Also, no jet bridge, passengers have to use stairs, which is hard for my elderly parents. What's the point of ordering wheelchairs?

One of the stewardess was really rude to a customer right near me. I ordered water and was given sparkling water which kind of surprised me as I've always been given still water but I didn't say anything. The lady after me ordered water as well and when she saw it was sparking water, she stopped the stewardess who then said very curtly "You could have told me sooner." Whoa...that was rude! Later this same customer had some liquid spilled on her as the same stewardess handed a drink to the person sitting next to her. I know it wasn't intentional, but it was rather strange. It was very hard to navigate how to get through the Frankfurt airport to our connecting flight. No one told us you'd have to go through security again so it was rather confusing as we didn't have a boarding pass. Luckily we were able to get necessary papers and get to our flight. Sadly, my luggage did not make it out of Frankfurt though.

Quick easy flight, checked my bag and was told to pick it up in LAX but my bag stayed in Frankfurt. I am tracking it with an air tag. I filed a complaint with Alaska Airlines at my last stop in SJC.

For context: 10 hour flight FRA-YVR. Newer A330 Neo plane. Crew were amazing - friendly and efficient. The plane is newer with great overhead space. My main issue is that the Premium Econ cabin is inferior compared with other airlines. Cute amenity kit (a plus). Food was fine, though I’d like to see more wine selection beyond 1 red and 1 white. But, seats aren’t as comfortable, and all Prem Econ and Econ passengers share only 4 washrooms. Washrooms in business are off limits. In addition, Condor charges for seat selection in Prem Econ. Ridiculous on a $1500 one-way ticket. Prem Econ configuration is 2, 4 and 2, and Condor put me and my partner into 2 middle seats in the group of 4 seats, meaning we’d have a single person to our left and to our right. Again, ridiculous. A kind airport agent was able to give us 2 seats in first (and exit) row of Prem Econ but these had no footrests. I wouldn’t rush back to Premium Economy on Condor.

The crew was friendly, but the comfort of the plane and the food definitely had room for improvement.

The cabin staff was very friendly and attentive. The plane was modern and fairly quiet in flight. The video screens are large and of high quality, and I liked that the documentary movie "Anselm" was available for watching.

The flight from Saskatoon to Calgary was canceled by WestJet due to the airline strike. Condor, as the main operator, did not inform us. We found out that information just when we arrived at Saskatoon airport. Fortunately, we had enough time to drive to Calgary airport and catch the flight to Frankfurt. We couldn’t claim compensation for the missing flight because nobody takes responsibility for this situation. When we tried to contact BudgetAir, they redirected us to Condor, and Condor redirected us to WestJet. WestJet keeps saying that they are not responsible for the ticket that was bought from a third-party company.

Because of luggage I had to upgrade to premium economy , which was worth it!

Every thing was fine. The food was lack luster especially after leaving from Italy.

Very good except for the screaming 5 year old that was allowed to yell and scream whenever he wanted too! The mom obviously had no concept of “inside voices”!
