First Flight got delayed had to get rebook for another plane ride to connect the next day the process was not helpful at all had to figure the whole processs myself poor service plane was small and customer service was horrible will not fly this airline again

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

Seats paid for in advance. Seat assignments changed by kayak 3rd party. Seats then changed again by Turkish airlines at the gate. Family seated on opposite sides of the plane yet money taken for seat assignments that were not honored.

Good overall. Seat spacing a bit tight between IST and ISB.

Excellent staff despite some trying passenger situations. Very impressed with their good attitudes and kindness.

Service was slow and checked bag was off last evening when flying business

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.

Everything was great except that everyone were putting backpacks and small bags in the overhead compartment instead under the seat so there was no room for carry on-s

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

Pretty standard for long haul international flying. Food was fine, tv/movie selection was great, wifi did not work at all, crew was pleasant enough.

The tv and remote didn’t work. The plug to charge our phone didn’t work.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

Very good, i got two seats for myself, and was comfortable with the blanket i got

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

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.

Both flights were delayed and we missed our connection. Our second flight was delayed 3 times. I have always had great service and never any problems with my flights on Lufthansa. My last two flights were, unfortunately, awful. I fly quite often to Germany and have had better luck with United than Lufthansa.

Excellent staff and flight experience. Would rather that I had upgraded to Premium Economy for extra space, but I will know to do it next time.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

Zero legroom or space in economy. Flight was delayed into Munich causing a missed connecting flight and other missed bookings. :(
