Great. A to B no issues. Everyone did their jobs exceptionally. All great. God bless America.

The response was very helpful and quick. Overall, it was very professional.

No complimentary snacks or food. Had to buy drinks and food.

The last row was empty and I sat there for two minutes. I was treated like a criminal for doing so. My wife wanted to get past the cart in the aisle and she was treated like dirt by the same black attendent..

The ground crew was very good. They communicated clearly and continued updating. The flight crew was fine. The flight crew on the March 20th flight from MCI to Portland was excellent.

The ticketing counter in SD was a mess. The lady handling the First-Class check-in seemed overwhelmed until a supervisor replaced her. It took almost 20 minutes to get once couple checked in, and then she started walking around the counters while 7 people just stood in line. Once her supervisor arrived, she announced she was going on break, never to engage with customers again.

WOuld have liked coffee or pretzels but other than that, crew and pilot and flight were great. Seat was great, too.

No outlets, plugs, way to charge the phone or service and no food on one leg o the trip, but other than that, great. Loved WIFI, the flight, the crew, the pilots, the schedule, etc. Great job. My new favorite airline!

On time, friendly and professional staff and crew Very nice new terminal in Spokane

It was a bumpy flight but the crew was very attentive and made it a safe and enjoyable experience.

It’s always a great time flying with united airlines.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

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.

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

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

Waiting area on top of stairs before Boarding the bus wasn’t great. Took a long time to load the bus to gate.

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.

Overall satisfied and would fly with them again. They could improve the check-in efficiency at BOS, we got backed up because it seemed there were passengers requiring much more time for check in.

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!

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.

It was too cold in the plane my feet froze

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

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???

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
