Lufthansa was an excellent experience, everything well organized and on time. If you desire healthy snacks, that I would advise bringing them with you. This is pretty much what happens everywhere.

Make your layover longer because you will need it for all the walking at Heathrow

Coming from Denver with London as a layover you will have to go through security again

Be early rather than on time for unexpected delays. The amount of travelers during the summer can be intense

Make sure your passport isn’t expiring within 6 months of your flight. Check in online. And get an e visa

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The seat and leg room was not good. The food and beverage service was good.

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

David went above and beyond to make our flight the best that it could be

No food service almost missed because of first flight delays

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

Very nice and friendly crew. Boarding system can be improved.

The Etickets had been changed (Why?) without notice ; Hence, that caused troubles when checking in. Not until I contacted my ticket agent and was given correct Etickets could I then check in.

Cleanliness of seats, trays, storage pockets need more attention, but everything else was good.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Good overall flight. Excellent crew. Food options could be improved.

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset. If there is option to use another company, I suggest to other people use them.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

The flights were in time and the bags arrived. well done

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

The United Airlines crew that operated this flight was subpar. They didn’t

Very small and uncomfortable seats, Hard to hear entertainment system sound. Horrible food. Staff doesn't care much about the passengers. 2nd time they didn't give me my vegetarian meal. They asked me regular food with meat. The airline and staff was from United airlines.

Checkin took along timen only.few angents available at.checkin desk. Customer support over phone no existence

At baggage claim, I was given the wrong printed ticket. The ticket belonged to another passenger for a different flight — to Zurich instead of Frankfurt (layover). I was even allowed to pass security, and when I asked the Lufthansa employee if I was on the correct flight, and why it was changed. The employee said everything was correct and I should board. When I got on the plane, there was someone in my seat, and the crew on the plane finally realized that I was on the wrong plane. When I got off the plane, nobody was willing to help, and the security refused to provide my original printed ticket. That was until I showed them that I took a photo of the ticket; once they realized I had photographic evidence, they were suddenly ready to help me. The Lufthansa employee began communicating with other airlines and found a flight that would take me to my destination via Polish Airlines. I was required to once again go through security, re-check my bag, and once again pay for my checked bag and weight overage fees. This experience was incredibly stressful and very frustrating, as you can imagine. A Lufthansa employee told me I would be eligible for a refund. Please tell me what steps I need to take in order to make that happen. Thank you!

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

The payment system was not working so was unable to connect wifi the entire flight

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,

Paid $180 for seat selection, and selection essnt honored. Have to call for a refund.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful

The internet was horrible. Plus they charged me $25 for service that didn't work which should have been free since I'm Concierge Key. The flight attendant Rick Young was excellent. Greeted me by name and very attentive.

Not good. First time flying AA in years and won’t be doing so again. We departed late and missed our connecting flight to Barcelona. As a result we missed the first two days of a Mediterranean cruise. No reason given for the delay. Got rerouted from JFK to Heathrow and then to Barcelona. Flight to Heathrow was delayed causing us to miss the flight to Barcelona again. Routed then to Palmero where we had to purchase transportation and a 2 night hotel stay to pick up the cruise there. Probably cost us $2k plus.

My flights were great and the crew on them was lovely especially the London to Barcelona flight as Al & AJ were so amazingly nice. I wish they would be my crew always as they have the best customer service. Sadly both flights were delayed the first one from Vegas was because they clearly loaded the cargo wrong the plane was off balance making us 2 hours late. This made me miss my connection and sadly it was challenging rebooking while I was on the flight. I will never use Kayak again as there was no customer service number or live chat and you rebooked me on a flight 2 days later. I had my mom call BA to change it which she did after spending an hour on hold. This should not be so difficult. My second flight was an hour delayed due to not being able to disconnect the bridge from the plane but I did finally make it home.
