KarenFlew with LufthansaJul 2026
I wish I'd know how big the airport was so I couldn't have booked assistance since I've got asthma. It was not good rushing through in the heat trying to get to the gate in an unformilliar airport.
Verified travelerFlew with United AirlinesApr 2026
Except for food, I definitely recommend flying Lufthansa. Jut to be better prepared, I would pack food if you take the flight from IAD to Frankfurt.
Verified travelerFlew with LufthansaJan 2026
Sadly since I never could reschedule that flight I don’t know but maybe when possible allow more than a 2 hour layover if there is a possibility of bad weather.
Verified travelerFlew with United AirlinesMar 2024
Pay extra for a little better seating. Definitely worth it

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

Excellent service, and came on time! Thank you for your dinner that was chicken with salat/, and 🍰 it was good quality food , the breakfast was very good with good cheese , butter,etc and the tea was very good quality. The space where I was seat was nice so I could stretch my legs. I dit not have the bread as I am in a keto died. Have great time everyone in Scandinavia airline.

You cancelled my flight and didn't arrange another. Sent no info except YOUR FLIGHT HAS BEEN CANCELLED. HERES WHAT TO DO NEXT. and the rest of the email was blank???

The first flight was delayed. We missed the second flight, which was rebooked 9 hours later. We missed all our arrangements for the first day of vacation.

Old plane, food not that great - lacked taste. Crew was nice but strict.

They lost my luggage and there is no update, no luggage and no hope that they will find it. It has been 26 hours since we landed

The stewardess was incredibly rude. The gave you only one drink with dinner.

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

Boarding and crew were excellent. Seat could have been more comfortable (hard on lower back).

A Lufthansa flight operated by SAS with a jettime plane. Fight was nice, no food but free tea and coffee.

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

Vegetarian selection could be better. Bread was too hard to chew.

Crew was friendly and competent. Food, wine, and entertainment were excellent except the raw tuna on the flight to Split. Recommend against serving that - at least as the only option. Many medical conditions do not allow people to eat raw fish.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Food was terrible Not many options Stewards dont care Delay

Every experience was good except for the lack of comfort in those economy seats. I never had knee pain until that flight. Those seats are uncomfortable.

One of my suitcases was left in Frankfurt during the layover. The suitcase arrived the next day so, I had to get a cab to drive me for over 200 kilometers to go back to the airport to pickup the suitcase. After I picked up the suitcase and left the airport, I realized that one of the wheels of the suitcase is broken. When I tried to submit a complaint, the system did not allow me to do that because I have to do it at the airport and I have only three days to submit the complaint. Given that I am staying 200 kilometers away from the airport, I am not going to go back again to the airport to submit the complaint about the suitcase. I spent all that money on airline tickets to go to Algeria to be on vacation not to go back and forth for 200 kilometers between where I am staying and the airport.

The organization and enforcement for boarding was basically non-existent.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

good entertainment package but rather small seats for business class

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

We had almost a 6 hr delay, primarily due to weather, the e problem was that they communicated this delay and its length very poorly. The boarding was chaotic - even though they had hours to figure it out! The plane was an old 747 whose touch screens barely worked and there was a faulty USB port under my seat rest (something that wasn't labeled as being there) They organized my delayed luggage well. And I could get updates on the Lufthansa website. My shirt connecting flight charged for everything except water. Coffee was over 3€

Seats were extremely hard and uncomfortable. as well as very narrow even though I paid an extra $230 for upgraded preferred seats. Very disappointed in the downtrend of Lufthansa and United Airlines.

Liked nothing. Rude staff. Incompetent crew and workers. Wont fly with again

United tried to bump me. We pay good money to get on the plane we are scheduled to ride in. To hell with United Airlines.

United was great. We were a bit delayed taking off but in the end only got to Frankfurt slightly behind schedule.
