I was expecting better service from Alaska Airlines. I registered for assistance since I have a disability. The terminal in Seattle, WA was very unprofessional and at times rude. The BWI location was the exact opposite. I will NOT consider Alaska Airlines for future flights.

I was expecting better service from Alaska Airlines. I registered for assistance since I have a disability. The terminal in Seattle, WA was very unprofessional and at times rude. The BWI location was the exact opposite. I will NOT consider Alaska Airlines for future flights.

It was very good and comfortable, Crew was also great

The flight was delayed almost an hour. No wifi on flight.

Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though

Delay of more than 3 hours I didnt recieve neither a voucher for food Attention disaster

Flight was 1:20 later than booked & I never received notice. At airport way too early. Couldn’t hear announcements on PA system. Crew fine. Retrieving luggage fine. Overall experience not good.

I will never take a red-eye flight again. Crying babies. Complete full flight. Could not get comfortable. Not fun.

Flight was OK, landing not good, boarding was ridiculous. Flight was to load at gate n11 25 minutes before boarding time it was changed to s5 which is 3 tram connections on the other side of the airport, I'm handicapped and even getting a sky cap took 10 minutes needless to say just made it to boarding only because it was delayed. I did learn a valuable lesson don't show up for flight 2 hours early.

Only issue was the 2 hr delay after an 8 hr layover. Very long day.

Same crew flew with us from Palm Springs to Bellingham, so they were great! Friendly and kind from start to finish. Great experience!

online check in was not available so i had to get to airport extra early. The flight was delayed and my luggage was lost. I had an argument with the person behind me who wanted to keep her bag on the floor and not allow my seat to recline on a 9hr plus flight. So overall, lots and lots of areas for improvement.

The flight was operated by Lufthansa. You can't expect much from them anymore. They have a talent in getting something wrong.

The food was the worst I’ve had on any flight I’ve ever been on.

The seat and leg room was not good. The food and beverage service was good.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Better seating for sure. The seats were so close together for such long flights.

We paid extra for the seats with extra leg room. But we were not allocated the seats with extra leg room nor refunded the money we paid for the seats.

Food is terrible. Flight is outdated and seats are not comfy.

Check-in at 4:30 am in the morning was very quick and efficient.

After checking in online i called United to make sure I have special food ordered ( kosher option). Representative I spoke with on the phone with assured me that special meal was ordered. On the plane, during meal service I was informed that there is no note about it and no kosher meal was ordered for me. Flight attendant said she will check if maybe was a mix up and meal is somewhere. But never came back with any update. So entire flight with no food...

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

Paid for a Premium seat...minimal recline, no footrest. Maybe slightly wider than a cheap economy seat. Zero chance of getting any rest on this plane

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset. If there is option to use another company, I suggest to other people use them.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

Flight was great only departure was delayed to saome ground crew issues

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

The United Airlines crew that operated this flight was subpar. They didn’t

Very small and uncomfortable seats, Hard to hear entertainment system sound. Horrible food. Staff doesn't care much about the passengers. 2nd time they didn't give me my vegetarian meal. They asked me regular food with meat. The airline and staff was from United airlines.

Checkin took along timen only.few angents available at.checkin desk. Customer support over phone no existence

At baggage claim, I was given the wrong printed ticket. The ticket belonged to another passenger for a different flight — to Zurich instead of Frankfurt (layover). I was even allowed to pass security, and when I asked the Lufthansa employee if I was on the correct flight, and why it was changed. The employee said everything was correct and I should board. When I got on the plane, there was someone in my seat, and the crew on the plane finally realized that I was on the wrong plane. When I got off the plane, nobody was willing to help, and the security refused to provide my original printed ticket. That was until I showed them that I took a photo of the ticket; once they realized I had photographic evidence, they were suddenly ready to help me. The Lufthansa employee began communicating with other airlines and found a flight that would take me to my destination via Polish Airlines. I was required to once again go through security, re-check my bag, and once again pay for my checked bag and weight overage fees. This experience was incredibly stressful and very frustrating, as you can imagine. A Lufthansa employee told me I would be eligible for a refund. Please tell me what steps I need to take in order to make that happen. Thank you!

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

Seats were not comfortable, and the problems started when we landed at Frankfurt airport. We waited more than 3 hours to collect our luggage, as a result we missed the connected train to Brussels. Our plans for the trip were ruined that day.

I missed my connection in Frankfurt and was booked to another flight to New York. Different destination and got downgraded from Business Class to economy. No Support from Condor at all. Very Bad experience

Flight 1.5 hours late; missed connection. Ground support for rebooking inadequate to the point of ridiculousness.

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.
