The flight didn’t exist, and the next available flight to Bozeman was the next morning. Luckily I was given hotel accommodations and it worked with my schedule, but to be told my flight didn’t exist and my booking couldn’t be found was so stressful.

The flight didn’t exist, and the next available flight to Bozeman was the next morning. Luckily I was given hotel accommodations and it worked with my schedule, but to be told my flight didn’t exist and my booking couldn’t be found was so stressful.

They ask for electronic vaccination status to be downloaded but then they ask to see it again!!! Whats the point of downloading?? Also economy class was allowed to board through business and were not told to go to a different line

So now even with a 200€ flight you get only water and a piece of chocolate, no more food. Aircraft was 30 minutes late and no information on connection flights.

Staff were professional, friendly and accommodating. Great leg room and entertainment. Even the in flight meal and snacks were good. I was not looking forward to my domestic connection with Delta. Unfortunately, Delta met my anticipated expectation. US based carriers could learn a lot from Lufthansa."
Pros: "Nearly all Flights on time"
Pros: "a320 was comfortable"

Pros: "It was all great!"
Cons: "I was denied boarding on the Dublin to Munich leg of my connecting flight from Newark to Munich. My ticket was booked through Lufthansa, but the transatlantic leg of my trip was operated by United. When checking in with United in Newark, I received two boarding passes, one for each leg of the trip. I arrived on time in Dublin for my flight to Munich and tried to board the plane for Munich with the boarding pass I had printed in Newark. After scanning my ticket, the Lufthansa employees at the gate informed me that they had no record of me or my plane ticket in their system. I showed them the email confirmation for my ticket, but they still could not find any record of my ticket in their online system. The employees seemed more concerned with boarding all passengers as quickly as possible than assisting me. After being denied boarding, I had to go back through passport control to change my flight, and ended up getting to Munich nearly 6 hours behind schedule and missed an entire day of vacation. A Lufthansa employee told me that out of every partner in the STAR alliance, United is the ONLY airline they have had this problem with. I find this inexcusable, I will be AVOIDING ANY United/Lufthansa connecting flight from now on."

This was a mass from the start I will never use this airline or Air Canada again they ruin my login and told me it's still usable we had a delayed for three hours on the plane. Never never again!"

Cons: "We had to sit in the plane for 2 hours before liftoff because of a hydraulic lift problem"

Cons: "Delayed - but made up for later!"
Pros: "The crew was very kind."

Pros: "crew was helpful, seats comfortable, leg space good, entertainment good. a good flight without incident. boarding and getting off plane went smoothly."
Cons: "vegetarian meal had no protein, just white rice. Vegetables were good. Breakfast meal was very light, almost all carbohydrate. Some protein would have been helpful."
Pros: "The crew was nice"
Cons: "boarding and unloading are nightmares. They really should load the planes back to front and if someone has a connecting flight, they should be allowed to unload first."
Cons: "Our flight from Dublin was delayed 2-1/2 hours. So we missed our connecting flight to SJC. Instead of flying back at 5:15 PM we flew back at 8:13 PM. But that flight didn’t leave until 9:00 PM. They rerouted us to fly into SFO which is about 1-1/2 hours further than SJC from our house. Not good!"
Cons: "The sound didn't work on my entire row for the in flight entertainment; it made for a long flight."
Cons: "Flight was delayed. Sometimes it’s not airlines fault. Not 100% clear on who was at fault. Toilets apparently water wasn’t working on aircraft. Upon landing at BNA a baggage guy attempted to rush us because flight was late and needed to get back to ORD. With no consideration for over 2hrs waiting"
Cons: "The flight attendants were the best"
Pros: "Customer service when my flight was delayed twice and then cancelled."
Cons: "I hated that there were sudden updates of delays just moments before we were supposed to board, then delayed for a day, then cancelled. I was fortunate to be re-routed to San Francisco (I am on the way) now, through United airlines. All in all, it was a stressful inconvenience."
Pros: "All crew very friendly & helpful. Went out of their way to help elderly gentleman traveling alone"
Cons: "Not sure why it was a Finn-Air flight when it was an AA plane and crew?"
Pros: "On time, arrived early"
Cons: "Nothing"
Pros: "Nothing Flight was delayed , which made me miss my connecting flight."
Cons: "Mostly the staff who were not friendly at all. Two of them were very arrogant and ignorant. I’m not looking forward to my flight home and I’m thinking of changing airlines. I’ll never travel AA again. Very disappointing."
Pros: "Crew very friendly couldn't be more helpful. Food snacks and drinks good. Very efficient boarding system the best I've encountered."
Cons: "Roof mounted tvs a bit disappointing and the films were just repeated. Coffee needs coffee in the cup, it was just milk and water no taste of coffee."
Pros: "Smooth boarding, the crew was really nice (and it didn't hurt that they were generous with the wine)."
Pros: "Loved all the meals. Tasty, well-coordinated."
Pros: "Staff was great. choice of food/beverages."
Cons: "The people in front of us were having a party all night during the quiet period."
Pros: "On time, efficient, new plane. No troubles."
Pros: "New plane, all kinds of entertainment choices including new movies, great flight crew, smooth flight."
Cons: "American check in software was down when we got to the airport. Created a very large line. Did not delay boarding, even though passengers still had to go through customs before reaching the departure gates. Had a bit of jog to make sure I was able to get on the plane."
Pros: "Nothing"
Cons: "When I purchased my tickets, American decided it would be reasonable to separate my husband, our 1 year old daughter, and myself which I was notified of only when I asked the customer service agent over the phone prior to our flight. She explained that she was unable to do anything about it. I then called American during my trip and spoke with another agent who said it was out of her hands as well and to take it up with an agent at the desk at the airport. When I checked in online, I was able to change our seats myself which was nothing that either agent even suggested. The lack of ability of these agents on the phone to help two parents traveling internationally with a toddler was unbelievable. American has terrible customer service."
Pros: "Lots of movies. Constant trash collection and drink service"
Cons: "Uncomfortable seats. Dirty bathrooms."
Pros: "We appreciated that American Airlines found us two seats together for the long Dublin-Chicago leg of our journey."
Pros: "Food was good as were the movies & seat"
Cons: "Gate supervisor (male) in Dublin was unhelpful. He announced theee times that the US Customes pre-clearance would close shortly. This announcement was in the gate area where everyone had already had to have cleared the Preclearance US Customs. Then when he announced boarding for priority and Business class he "pointedly" told the zones 1 thru 4 to all begin boarding at once (w/ one agent while three agents stood behind chatting) and to only use the one Priority lane. Thirty people all gathered for the very slow process. The Gate Supervisor the says he would start boarding Zones 5 and 6 in the other lane. Zones 5 & 6 all boarded while I (zone 1 passenger) and five others were still in que boarding thru the priority lane. Poor leadership. The Business Class flight attendant while serving snack, spilled my hot tea on my shirt, trousers and iPad. She was very apologetic and said that she wished she had not filled the cup so full. The tea "happens" and was no big deal. The Gate agent on the microphone in Dublin was having a bad morning and transferred his unhappyness to me, which I did not bargain for on the 27th."
Pros: "Nothing it did not exist"
Cons: "You cancelled my flight without telling me"
Pros: "Fast and early"
Cons: "Tv screens kept freezing"
Pros: "Comfortable seats, for the most part friendly crew, with one exception. Flight left right on time and landed with no extra time to taxi. That was a welcomed benefit."
Cons: "No wifi on plane and no individual tv's for movie selections. Also had to pay extra for an aisle seat. Could not select seat at time of purchase. Didn't know if I called Iberia or American to make seat selection. Confusing with two different flight numbers. One from Iberia and one from American. Passengers should be made aware of which airline they are flying on at time of purchase."
Pros: "Smooth flight, good crew, no other problems."
Cons: "Several video system restarts and my arm rest USB and audio jack randomly stopped working for the whole flight. Lots of people had no video screen working too. Food tasted good but had so many chemicals in it that I had digestive issues the whole flight from both meals."
Pros: "I wish I could remember the names of our flight attendants- but they were wonderful and really took time to get to know passengers! They were so friendly and went above and beyond in any of our requests. Loved them!"
Cons: "It would have been nice to have individual screens for such a long flight, but I wouldn't say that's a complaint. The flight was fine."
Pros: "Everything! Leg room"
Cons: "The touch screen for entertainment was maddening!"
Pros: "The service and the food was great and getting to watch new release movies was a pleasant bonus"
Cons: "We did not get the seats we purchased but we did get a refund"
Pros: "loved the movie selection and how nice the crew was"
Cons: "The fact that my party was seated in different areas of the plane."
Pros: "Crew was very nice."
Cons: "Didn't have much option of food because I don't eat meat or dairy. I had the sides of salad, bread, and crackers. I'm used to not having many options as a vegan and don't expect there to be much available, but just commenting."
Pros: "ON TIME!!!!! Nice folks, smooth and safe."
Cons: "Got through the extensive security lines to USA one hour before scheduled departure and looked at the screen which said 'final boarding' which was not true and made us panic a bit, running for the gate. It did board and leave on time but not an hour early. This flight was night and day different than our ORD to Dublin flight of 5.12.17 which was 5 hours delayed and do stressful."
Cons: "We didn't fly Finnair. All of my emails said Finnair and then when arrived at the Finnair counter they didn't have my family registered. After some panicking, we were told to try American Airlines. That is who we flew with, not Finnair"
Pros: "My wife and liked the food selection during both flights. We also liked how one of five flight attendants actually seemed to enjoy their job. And also how that one flight attendant made sure we were taken care of."
Cons: "Initially upon arriving in phili, my wife and I boarded the plane and I walked on the plane first than immediately my wife was asked by a flight attendant if she was supposed to be on the flight without any explanation at all, it was weird and disheartening. Also other than one flight attendant actually seemed to enjoy what they were doing, and I am a big customer service man, and some of the attendants didn't seem to care AT ALL at many points, very disappointed. Also he plane that we took out of the United States to go to Ireland was very small, and the plane to return us to the states was very small as well. The flight from our connection in phili to go to Charlotte was the biggest plane we had, just for a two hour ride.. really disaipointsd with American Airlines."
Pros: "On time"
Cons: "No gluten free food available"
Pros: "Nothing"
Cons: "Plane was falling apart. Food served frozen cold. Entertainment was commercials then nothing for hours. Crew was a mess and rude. Flight from hell."
Pros: "The crew was great!"
Cons: "No leg room, tight."
Cons: "It is disgraceful flying such a tight configuration on a transatlantic flight. AA should be ashamed."
Pros: "Got an economy extra seat without upgrading, had a variety of snacks and service extras which were nice"
Cons: "Was never asked for dietary restrictions so no vegetarian meals were available, pretty old aircraft to be flying that route, no seat back entertainment"
Pros: "The movie selection and how often we were given beverages."
Cons: "I was selected for a random inspection. I was pulled aside and went through a separate check in process. I completed everything I was instructed to do and as I'm boarding, I'm pulled aside and told I needed to go back to pre clearance because someone forgot to punch a hole in my boarding pass. The stewardess and j had to run all the way back to security so I could go through the whole process again. I delayed the flight and everyone was upset. It was completely unnecessary. Simply because one employee didn't do their job, I delayed a transatlantic flight to Chicago. Best part, I arrived at the airport four hours before my flight. Also, the seats are incredibly uncomfortable. And I was separated from my traveling companion for this entire process. Had I missed the flight, she would never have known."
Cons: "The flight movies and entertainment were down the whole flights but only for our seats. Which on an international flight was the pits."
Pros: "Individual screens worked well, food was good."
Cons: "Flight attendants with carts bumped my boyfriend's shoulder repeatedly, nearly every time they went by, without ever apologizing. They were also really rude when we asked for additional beverages. I travel very frequently, and I was shockedz"
Pros: "Available drinks"
Cons: "Poor selection and no coffee"
Cons: "No entertainment systems Chairs were old and uncomfortable"
Pros: "The food was good and the flight was short."
Cons: "It would be nice to have more room"
Pros: "We had a safe flight."
Cons: "If we wanted to fly on an old American Airlines plane, we wouldn't have purchased a British Airways ticket. Deceiving and unfair."
Pros: "The captain and the flight attendants were very communicative and kept in touch with the cabin at regular intervals but not intrusive."
Cons: "There were 2 meal choices., one was chicken and one vegetarian curry/rice dish. Clearly the chicken would be the most sought after meal and the flight attendant even suggested the possibility that everyone would not get their first choice, and ofcourse they didn't. We had a group of 10 traveling and by the time some of,our group was served the chicken was gone. Our daughter was 7 months pregnant and was one who didn't get a chicken meal. I don't understand why the airline would not provide an adequate amount of meals that would apply to the masses. Only a few vegetarian to fill in for specific diets would be expected. We all felt this was poor planning on the part of the airline catering company.."
Pros: "The food was very good! Chicken and mashed potatoes with broccoli was very tasty! A very small salad, a seeded bun, cheese and crackers and apple crumble rounded out the meal. Later pretzels and the grilled cheese and blueberry pastry. Pillow and blanket nice."
Cons: "Movies hard to hear with provided ear buds. I tried three and gave up."
Cons: "EXTREMELY LONG CHECK IN & SECURITY LINES"
Pros: "The crew was very friendly and customer service oriented! They were very organized and always helpful!"
Cons: "Some of the screens on the chairs need to be looked at. It was extremely difficult scrolling thru the options because very often our screens would get frozen or land on an option that we did not select."
Pros: "Size of plane On time departure Meal choices were excellent Entertainment choices were excellent"
Cons: "That this became an American Airlines flight after booking and no one from either airline contacted us to tell us. We couldn't find the Finnair flight anywhere and came to figure out that American was handling this flight."
