Issue with boarding, group of passengers on a religious trip coming back to NYC kept trying to change seats, even standing when the plane was pushing back. Crew/Pilot kept very good composure, some passengers got aggravated and started venting out loud but this group created a serious security risk. Crew/Pilot should've been more stringent and called in security or remove them from the flight.

Amazing crew, delicious food and drink selection. 12hr felt more like a 4hrs. Comfortable beds. Can’t wait for the new business class cabin

Flying business class saves you. Once you get out of the terminal and onto the plane, it’s fine. The traffic at the gate is a horror. No organization at all. The fact that Business class is promised early boarding is a myth.

Every time I fly LOT, I swear I will never do it again. And changing planes in Warsaw is a horror. Not even remotely organized. I can only feel sorry for the staff who have to put up with it.

The seat was paid for but given for some different person .

Good in general, but i think the chair is not comfortable for traveling more than 2 hours ..

Krakow airport is very disorganized. nice seats. friendly crew. long legs had screens. short leg did not

Horrible communication, flight boarded then we sat on plane for almost 5 hours as the runway was barely covered in snow with no plows in sight and the as we tried to taxi there was a major equipment failure due to poor push off technique causing all passengers to be taken off the flight to ultimately have the flight cancelled. There was barely any communication to passengers as to what was happening or what to do next to get placed on another flight. Arriving to my final destination a whole day later having to take a connecting flight through Lisbon to ultimately end up in New York instead of a direct flight as none available for the next day. Never flying LOT airlines again!

Although I was flying in business class, the feeling, comfort and in general the whole experience was like flying in a low cost airline. Boarding by. Us, no priority to business class passengers. The plane was very old and looked poor and rely old. Seats do not recline. Space between rows very small. No separation between business class and economy. No separate toilet for business class passengers. Of course no entertainment, no WiFi and no charging. Very bad experience

Smooth flight, excellent crew and good food. Not enough space; sitting are too small.

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Everything could have been better. What needed to be wrong with United went wrong

It was good. The seats in economy weren’t bad

Very good. Comfortable and I felt well taken care of from start to finish

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.
