Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

My luggage is lost and nowhere to be found, no response from airline

Boarding was a shitshow. Had to bus to the gate. No separate bus and boarding process for Business Class.

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

Need to pay for headsets, water, or any extra except air to breath.

Sitting space was very tight and I am not big or fat (I am 5'10" 178 Lb), so eating was very challenging. The rest was good.

Sitting space was very tight, so eating was difficult. But everything else was good.

12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

Need to pay for a cup of water. No food. Need to pay for headsets.

Everything should improve! Service like a low cost but prices like a premium airline. Crew in general with bad manners arguing for everything. You pay for priority access but then they use buses, so your loose your advantage to put your carry on first. That was the purpose for paying for priority. Bording is a nightmare, people accessing the plane for bothering doors, front and rear, no matter which line do you have.

Good Poor. service onboard No food. Low quality for economy plus

It was extremely cold in the back of the plane. The seats are uncomfortable and space very small. Crew was excellent as usual.

Chairs do not recline. Finished the trip with an aching back.

Iberia lost my bag, said they found it in another country, said they sent it to me, but never did. Went my whole trip without my stuff, but expecting it to show up because that’s what they said would happen. Their communication sucks, their website sucks, and to top it all off, their seats are small and uncomfortable. They’re bad at their jobs and they should feel bad about themselves. Do not even get me started on the flight home. AVOID!

The flight was delayed over 4 hours. Business class is just slightly upgraded economy.

One of the crew members hit me with the car and not even says anything

It was a wonderful experience with great food, great staff, and no difficulties boarding!

There's not enough leg room in economy class. The seats are very narrow as well.

Well my luggage was damaged and they lost the plastic cover. I need to file a claim and I would like for someone to follow up with me on this. Thanks.

Provided a good service and I will use it again. Thanks,

The flight was ok but chargers did not work and the speakers in the back of the cabin did not either. But I am writing because the crew was really, really rude and not only rude but had the curtains always closed, forgot to clear our trays, the bathrooms were filthy and trash was building out, and one of the attendants even had her EARBUDS on while in the cabin. From movement it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. when we deplaned the crew in the back was just chatting with one another and the first class attendant was briefly and said goodnight. It is nice that a crew gets along so well, but they did not take care of passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller but I thought you really needed to know. Thank you, Carin

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

Liked the flight being almost on time (airport issues created a delay). Disliked the issue printing tag bags on the kiosk and having to wait for an hour on like to drop my bags.

Comment for Lufthansa is just perfect, similar to my first flight comment.

The food not that great. Did not like the fact that we could not purchase upgrade at the airport

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Overall excellent service and Frankfurt Airport was very efficient and clean

They lost my luggage and despite all follow ups through emails and phone calls they don’t give me an update

If I book through Lufthansa, I expect to fly on Lufthansa, not discover. Food was bad, plane was delayed. Will not be flying Lufthansa again.

They are professional. Nice crew. Still flying Boeing 747. Thank you for that. I love this airplane. Traditional.

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.

The staff was very good, the only thing was the air conditioning wasn't working during the boarding process so it was very hot inside the plane until we got airborne. The food wasn't great, the chicken was dry and hard to cut, the ravioli was ok and the little pizza pocket thing was pretty bad. Other than that is was a good flight all around

Everything. Boarding, service, food, seats, crew I'd increase the air pressure to avoid dry sinuses and after effects

Flight bumpy and aircraft old with tape over seats , it seems there is a lack of maintenance, air pipe blow off in the middle of the flight, flight attendant seemed not to be worried about it. Food got very bad over time , not only for the quality but for the quantity . Seats are very uncomfortable , entertainment not working properly.

The crew were great and constantly cleaning bathrooms and taking care of passengers. Flight was on time and arrived on time. Boarding was easy and hassle free. Food could have been better but decent selection. Overall recommend and will fly again.

Everything was good except the bathrooms were usually dirty and the trash bins in the bathrooms were full.

At least it was a direct flight, however the boarding process was a nightmare. 2+ hours in line to check my bag. Then told it was overbooked and I have to go standby even though I bought my ticket months ago. Then sent to another line to get on standby - another long wait and finally started yelling that my flight was boarding. They sent me somewhere else. In the end I did make the flight - among the last group to board, even though I arrived 4 hours early at the airport. Worst check in process I've ever experienced in 50 years off flying.

Boarding was chaotic. Service was poor. Attendant was slow and rude. In business class, I was not offered a drink until 1.5 hrs,after takeoff. Food was inedible.

I don't like anything in this flight the food was bad the service was bad the flight was old and not connected to the screen no intertainments at all and it was long trip was bad intertainments the crew not helping

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!
