Boarding was slow -- we ended up being late to take off. It was a packed flight, and there is no effort to board in any orderly fashion. The signage went up pretty late too, so figuring out where to go added to the chaos. The food disappointed me this flight with choices that were not totally to my liking.

Everything could be better.Call center is so bad.You can't fix anything with them.

I’m leaving it really bothered me. My bag did not come in on time and I had medication in that bag that needed to be in the refrigerator and I still throw it out. Are you going to buy things because it came so late

The food and drinks were good. Other than that airplane cabin and bathrooms were dirty and airplane was HOT.

I did not like 2 3 2seating. The food quality was declining. The appetizers were good. But the main course was limited and I had to send back my lamb chop which was too dry. The meal before landing was disappointing and not appetizing.

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

The seats were extremely small. Boarding was not communicated correctly. It wasn’t a pleasant trip.

Loved the food. No wheelchair was provided in Sofia even though wheelchair assistance was confirmed by Turkish Airlines

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

I need to note that this flight experience was generally fine but the boarding situation was absolutely a mess and there wasn’t any actual priority boarding. I rated the experience poorly because I’m am genuinely so frustrated with the crew on United taking the baggage space in first class. This flight it didn’t happen, but the last few flights (when I ironically don’t get an opportunity to provide feedback) have been spoiled because upon entering the first class cabin as one of the first few seated passengers, the overhead bins are full and ‘crew’’ tags are on the bags of those taking space. I don’t intend to infer some sort of a class or caste system but it’s absolutely ridiculous that the crew takes the overhead storage above and beyond their most loyal and lucrative customers. They should not even have economy space IMO. And I’ve gotten grief when I’ve noted to the crew the ridiculousness of the notion that the crew (who are the last off the plane) should have priority over flyers who pay. I hope you find a way to convey this message to United because it’s happening with increasing frequency and I intend to find a way to expose the specific crew members who are doing this on a flight by flight basis. (And I have a day job)

Seats needs to be wirer and food is very poor

Pretty much the exact same comments for this flight, there was crazy weather!

I have been flying united for a long time but now I’m done

1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.

Return flight was perfect. All on time and no hiccups. However, going was another story. I don't blame United for the weather, but I am rather disappointed in its response to my getting stranded in my layover city for the night. United gave me a $20 food voucher. That's it. But besides this policy, the employees were incredibly helpful rerouting me to my final destination in Fort Lauderdale, FL. So overall, 8 out of 10. 10 out of 10 for flight comfort, inflight service and before flight service. 5 out of 10 for layover handling.

Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

Short flight, crew and staff very efficient. Over all good flight experience.

Inoperable monitor left no entertainment for 9 hours. The crew was not helpful. Food was awful.

I was not aware that I have to pay for the checked bag on the return flight. It was included in the price when I bought the ticket

how cold Sofia - Munich (first leg of an overseas trip Sofia to Boston, with transfer in Munich) not have any in-flight free snack and drink and one has to purchase those separately - at very overpriced prices at that, despite the high price of the ticket itself! I will will Ryan Air or Wizz Air and pay low-budget ticket if I wanted a zero frills flight. This is not acceptable. Coffee/tea and a mini sandwich or snack should be served on the 1st leg of an international trip with the airline.

No food available for purchase on a 2:30h flight around lunchtime… Lufthansa hand luggage policy and behaviour makes you feel you’re on Ryanair but paid three times as much

Food was terrible. Bamboo utensils are just not working out. A lot of plastic waste. Pillows and blankets were not good, a lot of static electricity. Crew did their job well.

Original Lufthansa flights were canceled and the alternative route that was offered required cab transfer in New York from JFK to Newark at my own expense. Who can refund these $218?

flight was packed, had to check my carryon bag, tiny snack bag offered, but we arrived on time and thats what counts

Expect Business Class seating to be 2 passengers per 3 coach seats, with center blocked. This is typical for flights within Europe on most airlines. Service was excellent!

They gave us chocolates twice (for whoever would like an extra chocolate - kids did!). I asked for an extra water, and I was given one. Crew was very friendly!

My mother is 87 years old and has knee problems. I have reserved a wheelchair indicating that she is immobile. For her it is very difficult to walk short distances. On arrival in Frankfurt, I was called via my mother's phone, by the female employee who had my mother in a wheelchair. She asked me how many and what color suitcases she has, which I explained. I was very surprised when 15 minutes later my mother walked out with her cane and balancing with great difficulties assisted by a young couple who were pushing her suitcase. Where was the wheelchair and the airport employee? I find this to be a disrespectful and abusive behavior of elderly people. It also raises the question of professional misconduct of the airport personnel in Frankfurt i.e. the female employee who abandoned an 87 year old immobile person by the luggage lane. I would like to inquire about the details i.e. name of that employee.

Crew was nicer to some people than others for no apparent reason. I had to get an older lady’s attention because she was too busy talking to passengers.

The flight was wonderful, especially the special assistance from airplane to airplane!
