I was pleasantly surprised with the whole experience. Thank you

I was pleasantly surprised with the whole experience. Thank you

There were multiple delays and the food was poor. Better food.

Motivated and friendly crew on a somewhat dated but well kept plane. Hd seats in economy may section, so legroom was excellent.

We were very impressed with Swiss Air. The service was exceptional. Unfortunately, we had a baby behind us that screamed for hours. , It was a nightmare, though I completely understand that it was not Swiss Airs fault.

Luggage did not make it to Miami still not today! Screen did not work for couple hours- got a bate of chocolate as a peaceful offering. Crew tentative, seats are getting smaller- isle seat arm rest foes not fold- problem getting other 2 passengers to go to the toilet without hitting themselves

Like the blanket. Food wasn’t good and boarding was a mess

Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

Hi. You canceled my trip and now you are asking me for review? Check my trip record and you will have my review. Call your customer service and you will have the answer. This was the worst experience in my life. Sorry for you.

Pros: "The crew was super friendly and attentive. Best in flight service I have received in a long time."
Cons: "The plane doesn't have usb ports to charge the phones, and as there are no screens or anything else, make sure you bring your battery pack."
Pros: "Flight was cancelled. Kayak did not notify us. We found out by accident. There was no customer service from kayak. We had to solve with with the airline"

Lost my suitcase. And communication was poor. No offers of compensation for over 24 hour delay of bag

Horrible trip. Plane was late , so late . the flight conditions were very uncomfortable.

Delay everywhere,5 hours,24 hours,missing all connection flights,terrible trip..

The boarding was delayed several times. The take off was two hours late.

I didn't understand why I couldn't do a check-in at home

Pros: "Quick Check in"
Cons: "The crew were not nice. They dont even pick up garbage during the 9 hour flight. They give you a gallon of water in a huge bottle without a glass and you are on your own."
Pros: "Nothing to like"
Cons: "This Iwa’s very bad experience. Never again will use LOT"
Cons: "The worse experience ever. I booked the flight and then they canceled it, i tried changing the dates but the website was giving me an error so i called them, after being on the phone for 2 hr some guy answered who seemed very tired and not thrilled working for LOT. Rood and not helpful, told me to try FB messenger and online changing again. Failed to get a voucher, refund or change the dates online, was still getting an error. on messenger they answered and told me i can get a voucher, i told them i don't want it and after that they stopped replying all together. good thing i got my money back by filing a dispute with my credit cart company."
Pros: "The seats were very comfortable. The plane was clean and the crew was very friendly."
Pros: "The crew was really great, seats like in any Airbus (I guess better then Boeing)"
Cons: "Very old movies as entertainment."

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

Overall experience is good with boarding and food. There was no entertainment provided on a leg that made it bit harder.

I paid a lot of money for seat selection and was miserable for flight duration

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

Staff had been really impolite at the boarding area and for both ways charged high extra fees without a reason. For the check-in luggage which was measured 3.5 kg and was confirmed by the stuff to cost 40 € , 60 Euros had been purchased from our credit card. When confronted staff did call us both liars and claimed to never have announced anything. Flight back , when not wanting to press a backpack in a measuring metal instead of hand measuring , staff got angry that one did not follow her order, which was than escalated by the team. Although carrying a baby anyways staff did not offer any help in the unreasonable process and than charged again extra money. Cabine crew has been friendly but this experience LL lead to not booking easy jet at all in the future. Check in process in Edinburgh anyways chaotic,to the family check-in and disabled check-in everybody else was guided for check in process, so people just getting in between each other, not possible to monitor your own stuff.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

Boarding great. Didn’t eat or drink so can not comment.

Total jobs worths over carry on bags, charged £96 extra for bags that were clearly hand luggage

We were told to check our bags at the last minute, and the communication was poor.

Lost our luggage in Heathrow. Showed up 3 days into a 7 day vacation. Very inconvenient and disappointing!!

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.

Charged an extra 65 pounds for overweight suitcase, Not told how much overweight but had no choice but to pay the price. Compare to Delta Airlines where I flew internationally a few days before with this suitcase and no extra charge by Delta. Comfort was horrible. I am just under 6 feet tall, and good that the flight was only 1 1/2 hours, because my knees were in the seat back in front of me the whole flight. I felt that my knees were part way up to my chest. No reason to have the seats that close. I will say to the positive was the flight crew, very friendly and efficient.

The flight was delayed as they were waiting on catering. Catering. Was eventually delivered but they still had no food. No meals for us in business class - just a bag of nuts.

Our luggage is missing. We are at the Hotel Gran Via in Barcelona

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The flight was on time and the crew very professional. Everything went as expected and I will use BA again for this trip.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.
