Airline reviews

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

David went above and beyond to make our flight the best that it could be

No food service almost missed because of first flight delays

Had a hard time finding my assigned seat. No attendants to assist.

The negative was the wait at the airport coming back. I checked my bags in, an hour before boarding and I get the notification that my flight was delayed. Rather had gotten the notification while I was at the hotel. Then it was delayed 3 x’s. Ugh!

Plane still had screens for watching movies. Good selection too.

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

Very nice and friendly crew. Boarding system can be improved.

The Etickets had been changed (Why?) without notice ; Hence, that caused troubles when checking in. Not until I contacted my ticket agent and was given correct Etickets could I then check in.

Cleanliness of seats, trays, storage pockets need more attention, but everything else was good.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Good overall flight. Excellent crew. Food options could be improved.

Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.

Flight was delayed then we had to redirect for medical emergency during which time we had no information on what is the plan. The connecting flight was also delayed.

Very helpful in getting us off the plane first to make a tight connection.

The seats were really cramped. The high backs on the chairs made you feel claustrophobic.

Boarding was chaotic and the flight left late but arrived at a decent time. This may have been because of the sxsw festival that was going on.

Nothing special or negative. Pretty typical flight…no freebies in the way of food etcetera, but none were expected.

The flight got canceled and you just send an email in the middle of the night and no solution to how to get on the next flight or provide other solutions.

They were all bad because SAS was at fault and cost me my time. I will never fly SAS again.

You cost me my time and did not compensate properly. Gfy.

Missed a connecting flight and SAS was at fault. I was awarded a $20 voucher in exchange for 8 hours of my time? Gfy.

Seat was lumpier than I’ve ever remembered it to be although comfortable when tilted back. I don’t recall being that hungry after being served food from SAS before. Flight attendant on the second flight to Aalborg seemed to be having a bad day.

I experienced trouble with the automatic bag check in. When I scanned the baggage tag I received, things were fine as the conveyor belt moved forward then abruptly stopped! My luggage traveled about 4 feet and I had to reach over a barrier to retrieve it. I went to another scanner position and when I scanned the SAS baggage tag, the screen told me it could not continue!! I went to another scanner position agent who had me put it on the conveyor belt by her & somehow sent it down the belt. I flew from Bergen to Oslo with a two 2️⃣ hour layover before connecting to LHR. My bag was NOT on the flight. I had no clothes for the next day when I flew to Boston. I filed a Lost Bag report and waiting for updates.

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!!!

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

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.

My flight was late from US to Frankfurt so I missed my connecting flight flight and I had to wait for long to catch the next flight which was very tiring. Otherwise everyone was very nice.

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

Crew was not happy. Very uncomfortable seats. When person leans back in front of you the screen is too close to me. Food was awful.

They lost my luggage and despite all follow ups through emails and phone calls they don’t give me an update

Everything went really well. Snacks could be better and there was no tea/coffee service after dinner. Crew was helpful and friendly.

Too much long line at the TSA and Security. Prepare for long walk for baggage claim.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

The boarding process was quite loud and chaotic. The flight attendants kept barking over the PA system about people needing to only stow large items in the overhead bins. During the one and only service, I was hit by the service cart. At the same time, a passenger was returning from the bathroom and the crew definitely saw him but stopped a few seats short of allowing him to sit down before starting service and made him wait a good 10 minutes before passing his seat and allowing him to sit down, after which he had to ask for his snack and beverage or he would have been passed over. Neither flight attendant thanked passengers as they left; in fact, I did not see them again once the plane door was opened.

Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.

The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.

The food was pathetic. There wasn't much leg room and recline space for such a long flight. No tea/ coffee for a 2-3 hour connecting flight without purchasing! Really!?
