The internet that was free was terrible, the turbulence was pretty bad - uncontrollable I know.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

My business class seat was inoperable and unable to recline for 10 hour flight.

It was good. The leg room was not great in Row 1.

They made us board and then deboard due to mechanical issue which delayed the departure by almost 2 hours and we barely made our connecting flight. These quality checks should've been done before boarding not after.

The crew was very kind and always smiling. The seats were great and I was very comfortable during the flight. The only thing I didn't like was that the lavatories got really dirty at some point during the flight. Other than that my experience was great

Crew was very helpful with mobility assistance from end to end. Very caring.

When we checked in my friend and I were sitting seperate. By the time we got to boarding, they automatically switched our seats. I really liked that.

Traveling with delta is always a pleasure from the take off to the landing 🛬 🥰

I trust Delta. I travel comfortable. The snacks could improve or could go to something as a little sandwich.

United was excellent. We had very good experience flying the carrier. Certainly. We will opt to fly them for sure. Lufthansa is out.

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

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.

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.

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.

Would've been great if Lufthansa union cockpit pilots didn't strike for 2 days and caused a chaos to my returning plans to USA, and then after rebooking a flight 2 days later tge plane departed 35 min later. So I did not have a good experience.

It was okay, the food was good, but after the landing there was not enough time for luggage and security to catch a connection. It was crowded on board.

Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

There was a big delay and I missed my connection flight

I was not clear if food was offered or not.

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

The plane was broken so we had to change planes.

The new seating in BC was a joy. My vegetarian pasta dish was excellent, very creative. The chicken potpie was ..... The crew was extremely focused and impersonal, but everything worked.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

Airlines must do something with overweight people... Maybe reserve a business class seat for them, or you could pay the consequences if someone overweight seat side by side to you in economy.

Excellent pilots in an extremely foggy situation. Very good communication with the passengers about possibly being diverted to another airport.

On time! Cabin crew attentive. Good WiFi sofrtvterm free internet appreciated

Iberia didn’t let me check in online or select my seats, the experience overall was not very pleasant

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

This is where i leave an airline review. Test test test!

The flight delay in Dallas created a domino effect that impacted all of the connecting flights. It also increased the number of connections. I missed my flight from Casablanca to Marrakech because of the tight turnaround when landing in Casablanca. . CMN airport was understaffed. Only one person could help while other employees were just watching him. It was an extremely frustrating situation. People were crying and slamming their palms on the counter when speaking to the customer service provider, Allabough (man’s name?). Allabough couldn’t change my flight in the system. simultaneously, I was on the call with America. Airlines customer service rep named Solomon that said he couldn’t change it either. So, I took a ONYA voyages train to from Casablanca to Marrakech to get there on Friday June 26. This was unpredictable trip.

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

Flight from Costa Rica to Madrid was excellent. Good food and service. The flight from Madrid to Brussels was very poor . No food , no entertainment, no usb … Total package was quite expensive so you should give same service on the second flight

business class food was pretty average otherwise it was a good experience

okay, will recommend from PR to Madrid, faster turn around

I would not fly with BA again. Packed in like sardines, constant request to turn down air conditioning due to freezing cold for hours and the food was pretty to look at but tasteless!

All went smoothly, no problems; friendly crew. I would have appreciated a head pillow ;)

Never made this flight it was unconfirmed by Iberia according to American Airlines This trip was a total nightmare, got to the airport in Wed March 8th after confirming all flights, only to be told by American Airlines that we are not confirmed on the flight. We met a pretty rude and unhelpful AA check in agent by the name of Ali. American said it was not their problem, contact Kayak/Chatdeal and sort out your issue.Chatdeal said all flights were confirmed and it is the airlines fault. So it went, we were kicked between American, Kayak and Iberia spending hrs on the phone- all said it is not their fault.Spent 9 hrs in the airport on Wed 15th trying to sort out. Luckily, we met a really nice AA agent Shawnna G who went way beyond the call of.duty to help us out. We were put the next day on Thurs 16th from DfW to San Paulo Brazil the onto Madrid!! Imagine that..10000 miles and 20hrs of travelling to get to Madrid from Dallas!! Our trip took 3 days to get there ..Wed 8th Thurs 9th and Fri 10th.Got there on Sat 11th, so lost 2 days of our vacation and a lot of emotional and physical stress on our 2 kids travelling with us.

There was no entertainment or food service (short flight). The flight was delayed more than an hour.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

Cancelled - booked on train; and then flights started running! I spent 5 hours with 2 changes on train while flights started and is 50 min

Lufthansa has a bag policy unique to Lufthansa. We all had a small carry on and a backpack (personal item) that we carried with us through multiple other connecting flights, no problem. With Lufthansa we were charged 80 euros each for the carry on at the gate, for this one flight. When asked they said they made an announcement… problem being that we had just arrived to the gate from a connecting flight and didn’t hear an announcement. While we were standing at the counter paying the ridiculous fee several other people were stopped, while countless others boarded with the same type of luggage and were not stopped. Crazy. Good news though, when we got on the plane half of the overhead bins were empty! After an already horrible experience the lady at the counter was also terrible, so that helped round things out.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

Boarding arrangement at Frankfurt was terribly managed with no proper guidance and the flight was parked far away from the gate. In flight entertainment device (touch screen) was not working at all throughout the flight. And on top of all this two of the checked in bags were found to be missing when we landed at Chennai. All this mismanagement at a very high fare of about $2300 per ticket is unacceptable.

Water in bottle and a piece of chocolate were given. We did have movies to watch.

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!

Good but I don’t received my bags yet is been 5days still no update

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!
