The layover should have been one where I could have actually reached my connecting flight in time if all flights were in time.

The layover should have been one where I could have actually reached my connecting flight in time if all flights were in time.

Our connecting flight to the US only had around a 25 minute layover! And our flight from Seville to Zürich was delayed! Had our flight from Zürich to Washington DC not been delayed we would have missed our flight to the US. We didn’t even know it was delayed until sprinting from the A terminal to the E terminal. Our flight from Seville landed in Seville 10 minutes after our the door was supposed to close for our flight from Zürich to the US. Not cool! Several other Swiss air passengers were in the same position as us, which I could tell bc we were all running for our lives in your airport. We booked a flight from Seville to Washington DC and the time between connecting flights was not enough and that’s not an acceptable position to put a traveler in. Especially one who spent over $1000 on their tickets.

Crew members were good. Seats were packed and too tight .

They went out of their way. It was very clean and friendly.

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

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."

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

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!

Food could be better quality - everything else was excellent , thanks Lufthansa team . GOD bless you!!!

Be sure to check bags for 23 kg,.(50 lbs) Coming from US I chose the wrong size luggage weight when I checked in on my phone, and had to pay more when I dropped it off

The on board air steward really made the journey. He was very entertaining

I was disappointed there was a 40 minute delay to flight

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

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

Really quick check in and security at Heathrow Terminal 5. Staff on board were lovely and very friendly. Could have provided a few more drinks on the flight but they were available at the back of the plane.

Flight boarded and took off late for unknown reasons. Crew insisted we check our hand luggage due to full flight, which it was not even close to full. Then had to wait almost an hour a and a half for the hand luggage to come onto the luggage belt since it was loaded last. This came after many hours of traveling pregnant with my 6 year old daughter. Really didn’t appreciate the unnecessary delays. What the hell?

Left late. Crowded like cattle. Standing and waiting. Food on board getting worse.

Terrible- the flight time was delayed and then I was denied boarding because I arrived at the new time of departure

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

Our flight was delayed by over 6 hours. We then had to deplane, stay overnight in a hotel then fly out the next day, 23 hours late.

I would have preferred something lighter for the second meal. Maybe a small sandwich .
