For my wife to be seated with our two children they put them in the last row on the plane where the seats don’t recline very much. The seats in front of them reclined fully which is basically in the lap of the last row which made it difficult to eat, move or watch the entertainment provided.

For my wife to be seated with our two children they put them in the last row on the plane where the seats don’t recline very much. The seats in front of them reclined fully which is basically in the lap of the last row which made it difficult to eat, move or watch the entertainment provided.

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

I missed my flight and had to buy new tickets Rome- Boston

Crew was great! Good meals. Had room to stretch out

The economy seat was much less comfortable for an international flight in terms of recline and moving space when food tray is expanded. Per entertainment, it would be amazing if I could connect my Bluetooth headset or ear phones to the entertainment screen. Or provide in-flight wifi to connect directly from my own device.

Horrible, absolutely horrible. The airline overbooked the flight, did NOT assign seats and boarding was a hot mess with lots of confused passengers. There was no "large plane" gate for us, the 500+ passengers were squeezed in a small hold room area, and multiple busses had to shuttle us to the other side of the airfield, where boarding of the plane, that was parked on the ramp, took place in rain. The old plane had a broken seat, that the technicians tried to fix - with no success - resulting in a 50min delay. The flight attendant with heart shaped earnings with German flag was screaming on the passengers without a reason, was extremely rude and entitled the entire flight. The food was junk. I hope I don't have to fly United ever again.

The clerk at check in for my bags was very rude. My credit card was hacked during my vacation and she told me it was not possible to pay in cash for my bag. “You bought the cheapest ticket, you should have bought a ticket that included a bag. If you cannot pay with a credit card, we will not let you on this flight”. She spoke to her supervisor and then told me , I could ask other passengers, if they would use their credit card to check my bag. I had to beg 5 different people, till one agreed to use their credit card. I payed them cash of course. This was a very stressful and humiliating experience for me. I strongly suggest you build in some kind of provision for travelers who got robbed.

Meals were poor and service rendered on return flight was mediocre as compared to the flight we took to Germany earlier where the attendants were more attentive, energetic, and mindful of passengers' needs. Thumbs up to crew of UA 58. Thumbs down to UA 59..

The crew was generally professional. Though one of the crew members seemed to be easily annoyed, the others were fine and helpful. The green olives and almonds snack was really good. A great idea, and nice balance of tastes.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

Awful. The Iceland airport was a complete mess. Boarding was a chaotic, the seats were awful, there was a group of rowdy 20 something men in our row hooting and hollering, ordering alcoholic drink after drink. Yelling and laughing at the top of their lungs and the crew just went along with it. Passengers complained to the men, asking if they could keep it down (it was a night time flight so people wanted to sleep). They never listened crew continued to laugh with them, flirt with them and serve them more drinks. No free food or snacks, seats were horribly uncomfortable. Worst flight I've had in a long time

At least one soda free, felt like I was nickeled to death.

Friendly flight crew. Airplane (757) configured as a domestic flight (no lie-flat seats) & no advanced meal selection.

The Icelandair crew was so kind!!! Thank you for making my first trip to Paris a great one!

I am not going to fillo this out for each leg of my trip. My first review holds for the experience

The movie choices were poor. The worst problem is the treatment of passengers durinng pre-boarding. In one case the primes were checked in and sent down the boarding tunnek only to stand waiting there while the plane is cleaned. In the second case the bus was loaded, the doors closed and just stood there unmoving like sardeines in a tin for over TEN minutes. In both cases it was rough on us old guys who find standing for long periods trying.. In other words, Donnt just stack us up and forget us.

I’m considering never flying with Iceland Air again. The seats in economy are torture. Now you only get water, coffee and tea for free- really? No food, not a single peanut. The passport line was insane, everyone was worried about catching their connecting flight. This was the third time I’ve barely made my connection, had to run. It can’t be that my choice is to use the bathroom (during the 50 minutes between flights) or make my flight. SO stressful! Ugh.

The most uncomfortable seat i’ve ever had on a flight

Too tight connection. Lufthansa staff pulled 12 of us out of passport control that had tight connections and took us about 1/3 mile AWAY from our gates and put us in another slow, long line. Needless to say all of us missed our flights and the Customer “Service” staff was rude and not helpful at all. Was rebooked from a direct flight to one w a 6hr layover. Asked about an other option that was on my app and was told to book it myself online (which would be $300 extra pp!!). Got rebooked again w a tight connection which was also missed. Rebooked into middle seats that didn’t recline for 9 hr flight!! No compensation (and we paid for seats!) Ended up taking 26hrs to get home from Europe to North Carolina! No longer a fan of Lufthansa—2nd time having these kind of issues w them!

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

The flight attendants were wonderful - one man put my carry on in the bin for me. Very attentive service. Loved the blanket and pillow waiting for me in economy. Food was excellent which is a surprise given the reputation of any airline food. Wine was fine with the meals. Delighted with the new movies - flight went by very quickly. I would definitely fly Lufthansa again.

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

It was good. The seats in economy weren’t bad

It was freezing cold, the flight delayed and then I got rebooked to a different connecting flight with a four hour waiting time even though I would have easily made my initial connection

They lost my bag and have yet to find it, they won’t talk to me or give me any customer service at all. I’m now having to contact Alaska to help me because Condor won’t give me any updates and it’s been over 24 hours with nothing

As I am 6 foot four and a large frame seek comfort was not very good hardly any legroom which I couldn’t enjoy my food

The flight was fine. The food was much better on the second flight. I have NEVER paid for a carry on bag on a zero economy flight booking. I'm very dissappointed about that, and will never fly Condor again.

Great crew. Food was pretty good. Seats are narrow and internet is expensive

This Condir premium economy is terrible. All it is is a few extra inches of legroom in an economy seat. British airways premium economy is the same as a first class domestic seat, wider with more recline. Plus the flights were all late to leave, arrive, etc. terrible day.

Absolutely the worst food I ever had on any flight. Half of passengers simply didn't eat their meals, as I noticed.

Food could be better. Service was just ok without any enthusiasm...

The breakfast snack was horrible. No nutrition value. I couldn't finish it. The main meal had no taste, no real vegetable, the brownie had no chocolate taste., I was not even sure what the salad consists off.

Our connection in Frankfurt was the worst ever. No one from the airline or the airport seemed to be bothered to get us into our connecting flight on time! The procedures at the airport took us forever and we barely made it into our flight. If we had missed it, I’m sure we would’ve missed our cruise. Looks like everything is on autopilot and no one is interested in helping customers anymore especially us 69 year olds
