The aircraft, crew, and entertainment were excellent. We knew that food was available for sale so we prepared a picnic lunch. All of the usual soft drinks were complementary. Boarding was organized and timely at both locations.

Cold weather and snow on Iceland meant that all aircraft needed to be de iced which took up some time. That is not the fault of the airline.

I booked and was confirmed for an aisle seat in July for my January flight. I checked in online and checked luggage and was still confirmed for my aisle seat. When I board at gate I was notified my seat was changed to a middle seat. Gate agent was unapologetic and refused to move me back to an aisle seat. I would never consider flying this airline again. 8 hours sitting in a middle seat.

Hard to say what I liked as my experience was soured right from the onset

I was surprised by being charged almost $100 to check in my luggage, and over $100 on my return leg. (Yes! I could have looked at their baggage policy, but there was no glaring notification alerting me to this fact when I purchased the ticket, nor when I was checking in online) Then, I was further surprised that you had to pay for food on board. This was a first. I mean, on an international long distance flight? Everything became mediocre after these, and I mentally swore off flying this airline ever again.

Flight from Brussels to Kinshasa was different. It seems for the people of color, there was an old plane. My seat mate TV sCreek did not work. You could tell moldings on seat were very old. one bathroom had no soap, dispenser was broken. I hope this is not your pratice to use your older planes for those traveling to Africa. I will observe this as I travel back to Brussel and on to US.

The food was great. The seats were soft and there was enough legroom.

We were stuck on an aisle where the seats don't adjust on one of the flights, but it was a relatively short flight. The boarding process was a little disorganized, but we were able to get on the plane quickly. The worst part was the home airport. I don't know how much control Turkish airlines has over that airport, but the bathrooms we're absolutely disgusting.

The Lufthansa crew is always wonderful as always.

screaming and kicking child behind my seat, with no way to "escape". I had a severe cold and that was certainly not something I needed, I tried to get some rest, but that was impossible. The seats are getting smaller and smaller, hardly any legroom whatsoever. Also, what I had planned on bringing on the aircraft as carry on (which was my work equipment, tablet/printer etc), I had to check in as luggage because it was "overweight" meaning more than 8 kg and pay ADDITIONAL $200 (in addition to the $100 I already paid for one suitcase). I've seen many passengers with "heavy" carry on, which they were apparently allowed to bring into the cabin without any problems. I had never had to pay for any carry on, and I am seriously considering using another airline for future business travel.

Not much to like on this leg of my flight

Was over an hour late to board and depart. Missed connection in Seattle, was then given printed paperwork for new flight which would not get us through security and then had to go back to main desk, almost missing connecting flight for the 2nd time. Little to no communication as to why we were delayed. Very little help from flight crew as to what our options were since connection was missed etc.

I never flew to Florence because the airline missed my connection and the next flight to Florence was not until nearly twelve hours later, so now I'm on my way to Rome instead. This ruined my rental car and lodging reservations, and I'm now fighting both those agencies because of this botched flight and poor service. Additionally, the plane was ungodly hot. So much so that the crew apologized for our over the PA. Nothing was done to fix it, but it was blamed on the plane only being on auxiliary power while we were parked on the tarmac for the hours. That would've been understandable, but it didn't get better when the jet engines were on, so that excuse turned out to be just so many lies.
