The crew were incredible, especially with how unruly many of the travelers were. Loved the pots and hummus and the food in general. The leg room in economy was plentiful, which was a very pleasant surprise!

The crew were incredible, especially with how unruly many of the travelers were. Loved the pots and hummus and the food in general. The leg room in economy was plentiful, which was a very pleasant surprise!

Did not expect too much, but an initiative to serve a small water bottle without asking for it would be appreciated. A small snack pack would be very nice too. Coffe any one?. Yes - you'll get an over heated chicken sandwich as the on board meal. Sorry - nothing to write home about.

The crew was fantastic, and it was croweded but roomy enough. But the sandwich was horrible and no entertainment at all which is difficult in a flight of more than 4 hours.

We were 3 people together and they seated us apart. My wife and I were both in middle seats which were very tight

The seats in business class were the worse I have ever experienced.

Check-in was quick and boarded plane on time. Seats were comfortable, large screen entertainment, slept almost entire flight. Staff was pleasant. What is great about ELAL is their safety, and ability to take a large carrey on trolley and no one cares about size or weight. No one is taken out of line because of excess hand luggage like they do on Wiz or RYANAIR.

My suitcase was severely damaged. I didn't realize the degree until after I exited the luggage area. I submitted an online form and was informed it might be a few weeks until someone got back to me. Ridiculous. I have to return to the USA with it?!

2 hours on the tarmac then another 20 minutes at the gate make for a poor experience

Very old plane, small, no screens, no charging ports. It was 4 hour of pain! I would not recommend this flight, not to mention that it costed $800, which is a total ripoff. Don't recommend!

Poor food. No seats screens only WiFi and not text messages. No in flight information for the flight . Took off one hour late.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Food choices were very limited. Taste of the dishes was average.

I liked all the informational texts. I always knew where to go and when .

Not as good as expected Air Can needs to improve totally rated on internet as worst

Received an email the night before showing that there would be seatback entertainment on our flight. We get on and there was no seatback entertainment. And then it was a scramble to try to set up the iPads for the kids before takeoff so they could watch something for the four hour flight.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

It was 4 hours late. Almost missed my connecting flight no food or drinks on connecting flight. Overall terrible experience

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

I was very happy with everything, thank you for the smooth flight ✈️

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

I enjoyed my flight back with Lufthansa because the food was good, and the flight attendants were nice and helped you when you asked a question. The flight attendants always came around and asked if you needed anything which I liked a lot.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

The flight was cancelled due to tech problem with the plane

I pre-ordered my meal and did not receive it. The seats are very old, uncomfortable and dirty. The crew was excellent and made my stay on board comfortable and enjoyable.

It was great. The airline staff was very friendly. The FRA security was a bit harsh doing their job but friendly overall.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

Delayed flight due to lack of crew caused me to miss my connection

Please make sure the number of seats matches the number of overhead bins and passengers don't carry on more than one bag.

Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable

Boarding was chaotic. Glad we were group 5 and still had cabin storage available when we boarded. I was expecting crew would get our carryons at the gate since theyclaimed it was a full flight.

Boarding crew is unfriendly as i was asked to handover carryon luggage too upto final destination Bangalore I was not prepared for that and i had to travel without my diabetic and hypertension medicines

American Airlines seemed to run a 'dry' flight. No alcohol was offered at any point with meals. Breakfast was a bit tasteless. The 'hot pocket' whatever that is, was horrid breadish pastry with very little filling. Decaf coffee was horrid. Seats didn't seem as wide or spacious as usual, especually for a ten hour flight.

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

Less than average, low level of shared required information needed during the transfer from airport to another, also the used team during boarding In Indianapolis station is Not Professional

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.
