Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

Pros: "Crew was great. Peppy and kind."
Cons: "ORD ZRH seats extremely crowded. Wished for comfy Star Alliance seats for that flight which we did enjoy from ZRH BUD"
Pros: "Crew was great. Seats were uncomfortable. No air. It was extremely hot."
Pros: "The inflight entertainment was great and helped to pass the time. The food was good for airline food."
Cons: "The flight staff was just okay - they could have been friendlier. The seat cushions seemed old - they were comfortable enough for sitting but not comfortable to sleep."
Pros: "Crew was attentive to passenger needs in a quiet way: without fanfare, did all possible to make it a pleasant, comfortable trip. In fact, went out of their way to get me a wheelchair ride to next flight, which I dearly needed"
Cons: "First flight was delayed due to circumstances outside of airline’s control. They managed to get us there and help me with wheelchair, etc to make flight. Great service and kindness"
Cons: "Chose the option with Swiss because it showed that a checked bag was included. Got to the airport and was told to pay up for each checked bag. Great start to the trip."
Pros: "Everyone was friendly, pleasant and very helpful. Upon arrival in Delhi our suitcase handle was broken."
Cons: "Leg room was really bad in economy and the only upgrade option was to business for $10,000 so of course not affordable for the average person."
Cons: "When I purchased the ticket I did not know that I have to pay for my bag. It would have been nice to know about this in advance"
Cons: "I had a carry-on sized bag which would have fit in the overhead compartment. I was told that it would not fit the Swiss Air compartment, thus was forced to check it at the gate. I expressed my concern that it would get lost (thus the reason I never opt to check bags) and was assured "They are very efficient in Zurich." When we arrived in Madrid, my bag was not at the carousel. I was told at Customer Service that it was on another flight, but that they could deliver it to my Airbnb between 4-7 pm. I had to wait there instead of enjoying my vacation to wait for my bag. The bag did not arrive until 10:30 pm. I did not have my clothes or belongings with me all day. Swiss Air in particular needs to update their overhead compartment regulations, as my bag definitely would have fit there, and could have avoided this entire situations."
Cons: "my first flight overseas. friendly staff. movies ..headphones..pillow and blankets included. 2 beverages included with meal. only downside was paying for checked bag. looks like that is included on the return flight so that won't be and issue on the way home. no issues with carryons."
Cons: "The back of the plane was significantly warmer than the rest of the plane. Very little leg room."
Pros: "Boarding was easy, flight was smooth and on time."
Cons: "Seats were snug, granted we had the less expensive tickets."
Pros: "service was great flight was on time luggage came on time"
Cons: "I don’t like how the food on premium economy is packed in a cubic box that is really messy to eat from which the small plastic cutlery. Food quality is good, but feels like being an animal being fed from a bucket."
Pros: "Crew was friendly and helpful."
Cons: "Plane was a bit old, inflight entertainment limited, temperature on aircraft fluctuated a bit. We were also an hour delayed in take off with no communication."
Cons: "This has nothing directly with SAS, but since I experienced it during my flight there, they are responsible of it. I was waiting for the flight at the OSLO airport waiting for the flight to LONDON. I had ample time to work on my computer. In the big room by the gate there was only one spot where I found three electrical sockets hanging from a pillar or post. To my dismay none worked. My plug would fall off from each. To document, I took the pictures of the useless sockets... I complained to the lady at the boarding desk (she left before the SAS staff moved in), she did not even care... This experience frustrated me and turned an otherwise pleasant trip into a bitter one. Please install some working sockets in your waiting room! Flight SK 809 Confirmation: LN9M6O Departure: Oslo & other airports (OSL) Arrival: Heathrow (LHR) Time: Sat Dec 2 2017 3:05 pm CET - Sat Dec 2 2017 4:25 pm GMT Peace, Edip Yuksel +1 520 481 1919"
Pros: "I liked the high-tech adjustment on the seats but i am 6ft2, 200 lbs (in good shape) and I have Parkinson's disease. The seat was just not roomy enough and I had to get up at least once an hour."
Cons: "The crew was very understanding and kind. The aft head was very limited in space too. A little more room would have been most welcome."
Cons: "flight was canceled and I have not heard back from SAS"
Pros: "Good boarding, crew nice and professional, lots of entertainment choices, plenty of bathrooms. Overall a very good flight."
Cons: "No opportunity to rest on flight back home and wine a bit expensive for a European flight."
Pros: "The crew was friendly, the planes clean, flights on time. The blankets were a very nice touch."
Cons: "On my first flight, I paid for use of wifi, but it kept kicking me off the connection. Repeatedly, the entire time. On the second flight, there was no option for wifi at all. It would have been nice to pay for wifi once for use all the way to my destination."
Pros: "Flight, once we got on one, was fine."
Cons: "The delay of the first leg from Chicago resulted in missing the Stockholm leg by minutes. They didn’t hold the plane, but told us if we ran, we might make it. The gate was closed when we got there. Also, apparently chicken sandwiches in Iceland contain shrimp, which I’m allergic to."
Cons: "Didn’t realize I was going to be charged $65.00 per suitcase. Checked three and that added$195.00 to my overall cost. The only thing we got on board was water everything else was a charge."
Pros: "Good crew and a smooth flight"
Cons: "Loudspeaker system lousy, could not hear any announcement from cocpit nor cabin crew about safety or flight progress"
Cons: "It was very warm on the plane for the 6+ hours of flying, making it difficult to sleep or be comfortable."
Pros: "Everything was good for economy class."
Cons: "The first leg of our Iceland Air fight was delayed, but they didn't update the departure time until after it was obvious that the plane wasn't going to be there on time. So we hurried to the gate only to wait nearly an hour. I wish they had updated the departure time earlier."
Pros: "I like the short trip from Chicago to Oslo, it is the shortest trips out of all the airlines. Staff is sweet and helpful, seats comfortable, and prices are reasonable."
Cons: "I usually travel with airlines that serve dinner and a breakfast. Iceland air is the only one I have experienced not doing that. Entertainment is a little more sparse than other airlines, often I get the same movies and tv series episodes on my way back from my trip as I had going there."
Cons: "The first leg Chicago to Iceland was uncomfortable due to the seats for some reason. From Iceland to London seats were much more comfortable. Iceland employees are the most friendly and helpful airline people I have ever dealt with."
Cons: "Did not get the extra legroom we paid for, plane was awful hot and stuffy. Crew allowed 3 kids aged about 4 to 12 to literally run up and down the aisle, running into people and screaming."
Pros: "On time departure and arrival Friendly staff Easy flight and good time of arrival"
Cons: "food for purchase"
Pros: "The crew were very nice overall but one flight attendant in particular was incredible. I didn’t get a name but he was friendly, welcoming, and kind."
Cons: "I sat in an emergency row with an empty seat to my left and really did not like how the passenger in the row behind me kept getting up and walking into my row to get his stuff from the bins."
Pros: "Amazing punctuality, both on the way out to Lisbon and on the return to London."
Cons: "Cannot really think of anything that needed attention on these flights."
Cons: "Maybe have one flight be on time. Train ground crew how to put on fuel."
Pros: "Good entertainment, great price"
Cons: "Had about 30 people on our flight that was taking another TAP connecting flight - missed the gate by less than two minutes - did not hold the plane when they could have"
Pros: "It got us to our destination."
Cons: "Seats sucked. Screaming kids. Wouldn’t let us bring our carry-on for the last leg: Lisbon to Barcelona even though there was room."
Cons: "Ok, it's TAP, it's a bargain, but the "breakfast" was a pitiful piece of meat on a stale piece of bread"
Pros: "Food was ok"
Cons: "Worst accommodations for baggage on a international flight in my opinion.Pay for a bag is the best advice in my opinion this airline barley lets you bring anything with. Disgusting plane it was so dirty I took a shower after this flight and the amount of dust in the air was visible terrible"
Pros: "Service and the price!"
Cons: "Lots of things but I’m sure TAP it’s working on this!"
Pros: "The crew was great."
Cons: "My baggage did not get delivered to the final destination, that could have been handled better."
Cons: "So many delays, no real info provided. When we had to stay overnight they didn’t mention it would take 4 hours to get our bags which actually never came. Airline industry sucks and deltas one of the worst."
Cons: "Seats don’t recline at all and wasn’t even offered water on a close to 3 hour flight. Bare bones service to be sure."
Pros: "Even with some departure delays we landed on time."
Cons: "The plane could have used some cosmetic detailing. The door to a cabinet in the bathroom would not shut and caused a problem with people being able to close the bathroom door."
Pros: "First time experience with Iberia. Very comfortable, friendly & good service."
Pros: "Madrid's airport is comfortable and modern."
Cons: "Unless you paid you do not even get a seat assigned until you get to the airport. No food or even drink unless you pay."
Pros: "Heathrow Airport has a lot of stores to keep you occupied"
Cons: "Late notice of where our gate was located. By the time we got the news, we went to our gate and the people were already boarding"
Cons: "A porter checked our bags at the gate without asking us whether we were traveling beyond London, so the bags were never transferred to the transatlantic flight nor did they arrive in SF. It wasn't necessary to check them because there was plenty of room in the overhead bins when we got on the flight. We immediately asked a flight attendant to help when I realized they might not go through and he said he spoke to someone who caught and tagged the bags to go through, but it still didn't happen. It would have been easier if he had just brought them to us on the plane. Another women's bag was taken with all her baby supplies and bottles in it for a 16-hour travel day. Very frustrating for all of us."
Cons: "I requested a vegan meal weeks prior and the only meal without meat had a lot of dairy in it. Not enough water was offered as well. The flight was delayed boarding. The leg room is pitiful on the flight."
Pros: "The entertainment system with movies was great, with plenty of choices and good sound. The crew was very good. Legroom on the seats was good. They kept the temperature in the plane just right. We could board first because we had a 5-year-old child."
Cons: "Flight was delayed an hour leaving Chicago, and arrived an hour late in Madrid. The screen was not updated in Chicago to let us know what was going on. It's a mass of people at the gate, with very little systematic lining up. One luggage piece did not come out on the carousel in Madrid. We had to wait 1.5 hr at the airport to confirm that they would send it to our Madrid hotel. Hopefully it will come. The food was mediocre. Pasta for dinner with little to no meat. Not even fruit. They are clearly saving money on the food."
Pros: "I am of average height -6 feet- and my knees were touching the seat in front of me. Not comfortable but not too bad either."
Cons: "Boarding was extremely chaotic."
Pros: "Nothing"
Cons: "Take off was delayed for six hours and Iberia's representative in Madrid told me me missing my train to Valencia is not their problem and Iberia will not reimburse me for the train nor the Iberia flight I had to take to get to Valencia. I've been an Iberia's customer for many years. Horrible customer service and poor airline service. Shame"
