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.

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.

Pay extra for a little better seating. Definitely worth it

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

Terrible airlines, kept lying to me about the fact that my connection flight was cancelled. Left me hanging until last min. NEVER AGAIN

Mediocre. Maybe due to Economy light. Staff was great. Space shrunk, not for me, and definitely not for Vikings. Food was decent. Assistance lagging. There was a possibility to upgrade to Premium economy, however my bid was immediately classified as low and not even considered (though well over minimum bid). Thus I was no bleeding dry.

Upon departing and landing, the man seating in front of me had his seat leaning back. Taking off nobody told him anything. Landing someone from the crew said something but the passenger ignored him and nobody followed up. Felt a bit unsecured. If this that is some of the basics are missed, what else was overlooked?

On time, reasonably comfortable for economy, decent food. All in all a very good experience.

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.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

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.

The direct flight was a superb idea; please continue. The seats were less than comfortable for such a long flight.

We missed that flight, and I am hoping that we will got the refund. It was very confusing to figure out about Aer Lingus operated by American Airlines. Then we bought another more expensive ticket to travel.

Flight crew was superb. Meal was one of the meals at altitude I’ve had

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

Customer service was excellent! The app was terrible, tried several times to check in without success! But the young lady that checked us in was absolutely terrific and helpful.

Horrible. I had to wait in Dublin for 4 hours for the next connecting flight which took my to London and than i had to wait 3 hours for the flight to Dusseldorf

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

Problems checking in both on the laptop and on the app. No free seating available at check-in as advertised - must pay for EVERY seat between $23 and $75. No way to cancel seat choice. App menus and site menus are not responsive, and some items are impossible to find. Crew and mobile assistance are friendly and helpful.

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

The flight was delayed and as a consequence we missed our connecting flight. Were stuck for another 6h in Reykyavik. Appreciated that we got a generous food voucher at least. Would have liked to see more information upon arrival including a person waiting for connecting flight travellers and informing already that we will not catch the flight and directing us to the office dealing with the matter; unfortunately that didnt happen and we hence first needed to find out whether flight had indeed left already and then locate the adequate office to help us with booking us on the next connecting flight. Also my suitcase broke and it is not clear whether it is happened on the leg with Iceland Air from DC to Reykyavik or on the leg with Lufthansa from Reykyavik to Frankfurt. Finally, understood that it is a low cost company but at least provision of earplugs for free would have been nice, instead of making them buy.

Had a screaming child next to us. Not the airline’s fault but still annoying.

Seats are way too much now with these new airplanes especially long flights like we had. I was 7 month pregnant and in a lot of discomfort due to small seats.

My biggest problem was the flight from KEF to DUB was delayed, which caused me to miss my connecting flight in DUB and we were forced into an unplanned 10-hour layover in DUB. Crew and boarding staff were all very friendly but this was a real inconvenience and especially uncomfortable for my disabled wife.

The seat size was more like a domestic than an international flight. In fact, i would compare the ammenities, quality and service to a short hall ryan air flight, which was unexpected for an international flight. The plane was extremely hot so sleeping was difficult. My biggest complaint was that they are very strict on carry on luggage only allowing it to weigh 10kg/22lb. I try to limit myself to a carryon so i don't have to mess with bagage claim, but the wieght restriction made it impossible. I have never had a carry on weight restriction (at least enforced) on an international flight. Will not be including them in future searches.

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

This time it was not good. The plane was not clean. It had a bad smell as if the cabin was not cleaned properly. The small sit pillows were dirty and blankets (even though they were packaged) did mot smell clean. Decaf coffee was disgusting and tasted like instant coffee.

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.
