The flight was extremely smooth, and so was the landing. Great piloting.

Plane was clean, staff was professional and flight was on time. No built in tv was still ok, as programs were offered that could synch to smart phones.

J was in the ER x 3...3 protruding discs...contacted Alaska many many days prior to cancel and request a refund or a credjt.. they only gave me 50 % credit....outrageous seeing how i have a doctors letter....just plain inhuman. AI sucks!

The flight was too short. No snacks or drinks offered.

The flight attendant was friendly and attentive. Although our interaction was brief—- it made a difference. The crew was upfront about turbulence. I like the Maui pretzels.

Everything was good. Please have a wheat free option for snacks in the future.

They are always so great! Friendly, on time if not early, organized boarding process. Great price too.

Crew very courteous. Boarding was great. Slow to get baggage at Denver.

Lester and the rest of the crew were such a joy. Also, I want to thank the pilots for getting us there on time, and safely. My first amd only choice will always be Alaska Airlines.

Not delay for a few passengers. That was uncalled for. If idiots can't make the flight on time thats their fault. Why should I be punished for them? No more holding the plane for one or two people

The food was terrible this time. Otherwise pleasant, quiet, on-time.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Gate agent at Frankfurt was terrible. She denied PRE boarding even as it was printed on the boarding pass. Refused to look at the boarding pass and literally shouting for no reason. Frankfurt airport has horrible and rude staff who avoids trying to answer any question at all. Overall, horrible experience.

They charged a fee for 1st bag checked. Others in same party were free.

from SFO-> FRA flight, AVML meal was significantly less compared to regular meal, especially no Desert, no Bread, no sides.

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

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.

We were in business class. the angled seats in that class do not have a real window view & the placement of the controls are bad. But we knew that. But the food options were mediocre. The taste was fine, but the size was for a child. It’s just really feels like United is skimping on everything. Even when we were in the Polaris lounge they did not have diet sodas. They said they were out no Coke zero no Diet Coke, etc. I do not think the portion of nuts they serve on the plane could get any smaller. Really a minimal service and offer for what you’re paying for in business.

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.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

They wouldn’t check in my luggage even though I had one checked bag prepaid. So I took my bag to the gate and tried to check it in there and two employees scolded me for bringing a large bag to the gate. I told them I was trying to check it in and that it was prepaid, and they said they couldn’t guarantee that it would arrive at my destination but they finally let me drop it off when boarding the plane and pick it up right after exiting the plane. There was no food, and there was no entertainment.

Delays at check-in, seemed like they were short ground staff at the time and some passengers needed extra processing.

Problems checking in both on the laptop and on the app. No free seating available at check-in as advertised - must pay for EVERY seat between $23 and $75. No way to cancel seat choice. App menus and site menus are not responsive, and some items are impossible to find. Crew and mobile assistance are friendly and helpful.

Food - Non-Existent. You pay for everything. It is strictly Pay-to-Play!

Never again. Terrible hospitality and human decency for an international flight. No food, no snacks, no beverages, blankets, pillows, limited entertainment. Tiny seats without any cushion and some do not even recline. I was shocked that they did not charge for seat belts. Never in my life have I witness asking for "spare change" for charity before landing on both legs of the flight. Icelandair can contribute on their own to said, so called, children's charity with the money saved from providing 3 centimeters of tea and water to hungry and dehydrated passengers.

Having been prepared for paying for everything on board other than water, coffee and tea the service was OK. Food and drink is expensive but the food was OK if limited in scope. Plane was clean and obviously well serviced. After complaining about having to walk in wind and rain to a get a bus to the airport the same thing happened at Portland. I’m sure you could get a terminal gate flight, complimentary food and drink for not much more money without traipsing through rain and slush in Reykjavik. Not bad but not great.

Iceland air transfer was bad. They lost my luggage and I just received it 11/1

The boarding process seem to take longer than necessary, resulting in a 20+ minute delay

It was too cold in the plane my feet froze

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

Very good, i got two seats for myself, and was comfortable with the blanket i got

Economy Priority seats are extremely uncomfortable. There is no way to escape the boxed in feeling, particularely because the distance between to rows are too short, the hard edge of the front row is keeping legs confined. There is no elevated place to put your feet. I am of average, European size.

Terrible. Both flights were significantly delayed, no luggage, made me check my small bag when many, many others had much larger carry-ons, not even a bottle of water . . . I will not fly Discover Airlines again.

I was deceived on the Kayak site expecting a ticket, but instead finding a "standby" reservation. When I tried to change the ticket, I paid almost twice the price of the original ticket. Then, the airline refused to give me the reserved seat I had chosen and paid for. I think I deserve a refund for this leg of my trip because I was doubly charged and did not receive what I had paid for. I put in a complaint with Lufthansa because the ticket was sold originally sold as a flight they listed. Someone here needs to take responsibility.

Service and food were excellent. Incredibly friendly and competent staff. Flight was delayed over and hour and I had to run between terminals to get my connecting flight.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

I tried both on line and by calling the Customer Service line to arrange for a special meal as i have food intolerances. I was under the impression from your service representative that I was successful. I was not. I cannot eat spicy foods and get very ill if i eat bell peppers. I could not eat either menu choice and no special meal was actually ordered. ( your representative tried to order it for a flight that did not have meal service!!! - found this out later). Your wonderful cabin crew managed to put together a fruit, salad, roll and cheese tray for me so I had something to eat. WHY WOULD YOU SERVE SPICY FOOD, WITH NO MILDER OPTION,ON AN INTERNATIONAL FLIGHT???

Crew was professional and great, flight was clean. However food was pathetic. I ordered a Hindu meal assuming no meat but they served chicken. Need to be very specific- Hindu meal should be categorize as Vegetarian - no meat or egg. Or it should be specific that we are serving meat.

Upgraded to premium economy at the gate. Well worth it!

The flight was canceled and airlines did nothing to accommodate the passengers. After few hours they booked me randomly on a flight that had long layover and didn’t provide any compensation or effort to help. The crew was rude, no representation on the airport. Everything needs to be on call and agents there had no knowledge or control. For everything, they were like we can’t do it and you need to file a claim later. That was not helpful at all and will not make my travel experience any easier. Very disappointed in their service.

Great plane and flight attendants. The person next to me had a DISGUSTING smelling mouth and breath, so that was nasty to deal with the whole flight. Brush your teeth, people! Condor was amazing, though :-)

It would be nice to have a cleaner facility, it was hard to access it. It was always full of people working in that space. The covers and especially the matt of bad quality and old. Many times reused. I would not use it. Food: the bread rolls were old, and food had strange choices. Chicken was terrible.

There was some nice staff when I entered and left, but the thrre flight attendants who served us were very brusque and rude. I have celiac and when I checked in, I tried to find the option to make sure my meals (stick on a 10+ hour flight after a 3 hour flight and short layover) were gluten free because I didn’t have time to get anything. Couldn’t find the selection for it, and every part of the meal and purchase options were gluten, so I didn’t get to eat. During check in the allergies section should be easy to identify and check so this doesn’t happen. Having more options for gluten free at this time should be easy.

Internet was advertised in-flight but not accessible. The foot rest in premium economy was stuck. For both nobody I asked was able to provide an answer/solution. However, this will not stop me from booking premium economy again, which I upgraded from my initial economy I had booked for my outbound flight YYZ to FRA.

Great flight, nice options for food and beverages. Fairly comfortable seats for a large person

Business class: or fist class: Seating absolutely terrible, same seats as everyone else , no space, we could not fit our knees in. I was sitting sideways since nobody else booked this business class. I wish we would have an option to select a business class for the main journey between USA and Europe, but regular class for the short flights in Europe.

The seating was exactly same as the rest of the plane. We had no space for our knees. In fact it was the tightest spacing of the seats I ever flew with, on a very old plane. (and we flew all over Asia and Europe) The same chairs. We were the only passengers in business or first class. Obviously funny.... The only difference was, we got a sendwich and we were offered a drink. Rest of the plane got a bottle of water.

The crew was great. Good etc was unacceptable for an overseas flight. Wine with a meal should be complimentary. Seat comfort /space horrible and I am 5‘3“ with heels on. Short haul probably ok but not on long haul flights
