Delay of two hours due to some mechanical issue. Staff was wonderful and the pilot did let us know what was going on.

Delay of two hours due to some mechanical issue. Staff was wonderful and the pilot did let us know what was going on.

We left 1.5 hours late due to a “maintenance” issue. Very poor communication as to when we would board & depart. The crew in First Class was uncharacteristically not friendly). Delay into Brussels cost me my connection to Rome so lost the entire first day of vacation ( had a 10:30am flight to Rome - ended up on a 6:55pm flight).

The bathroom was nasty. It has been so long since it had been cleaned that there was a urine cheese inside the toilet. The crew seemed miserable. The one black girl took no pride in her appearance. The experience felt trashy

I purchased a Polaris ticket. The plane did not have the lie flat seats - I was not notified. I actually can not believe they traded a dif plane and did not notify me or refund monies

One of my checked luggage was damaged. Cracked on the top by the handle.

⭐ Absolutely AWFUL Experience with United Airlines! If I could give United Airlines ZERO stars, I would. The seats have practically NO legroom, making the flight feel like being crammed into a tin can with nowhere to move. Comfort? Forget about it! And the fees? Absolutely ridiculous! They seem to charge you for EVERYTHING. You pay for your ticket, then get hit with extra charges for things that should be part of a decent flying experience. What’s next, charging passengers for breathing? Flying with United feels less like being a valued customer and more like being a walking wallet. The seats are uncomfortable, the legroom is pathetic, and the constant nickel-and-diming is infuriating. For the price you pay, you would think they could at least provide a little space to stretch your legs and a travel experience that doesn’t leave you feeling ripped off. Do yourself a favor and look at other airlines before booking with United. I certainly won’t be rushing to fly with them again. Absolutely disappointing from start to finish!

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

Ridiculous boarding. Enter the gate, walk down a staircase with bags, exit a building, get on a crowded bus, dropped off a few meters away from the aircraft, walk with bags to another set of stairs to board the aircraft. And all that during a pouring down rain, and with children. Ridiculous!!!

Lufthansa no longer offers any refreshments and snacks on short i.e., around 2 hrs flight. We still had full staff stewards/stewardesses. No idea why they were needed as there was no work for them during the flight

Flight was great. On time. Pleasant crew and responsible passengers. My only disappointment was that there was no coffee or tea offered. It was a short flight but a coffee would have been appreciated for what the price of tickets are now.

The new buisness class pods are 100% worth it. Loved it.

Pretty bad. No welcome drink (the Lufthansa signature drink they advertised but did not serve). No 2 round of beverages. No coffee to end your meal. No snack before landing on an overseas flight. Mediocre everything and unattentive staff. Munich and Frankfurt as connecting flight airports are terribly big (20 min walk for transfer!) and confusing. Will not fly again.

My premium economy experience did not live up to my minimum expectations. I've taken this flight twice in the last three weeks, and each experience was the same. The premium economy seat was worn and extremely difficult to recline. It took two people to return it to its takeoff and landing position. The food was OK, but for the premium that a premium economy seat cost, I expect a satisfying meal. Years ago, I looked forward to the experience of flying transatlantic on Lufthansa (I especially enjoy the hot towel before the meal), but this is not been my experience recently. I'm not going to use Lufthansa again.

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

Not available crew to load the luggage for all the passengers,comon situation for local European destinations , not acceptable situation, never Lufthansa again 😉 🙄

We had to board and unboard, this could have been avoided

Always left late, food horrible and customer service not helpful.

Flight was overbooked. Crew did a great job but passengers weren’t nice and really not patient. Flying in these times is not the best idea tbh.
