Fine, the process or boarding was a bit slow but the flight itself was quick and smooth. Not over booked and pleasant overall

Fine, the process or boarding was a bit slow but the flight itself was quick and smooth. Not over booked and pleasant overall

More check-in counters or faster processing. I arrived early but got to the gate just in time to board the flight, I didn't even have time to use the bathroom. The plane was really dirty, encrusted dirt is everywhere and the plane smelled bad when I entered.

I couldnot board the flight since my previous flight from Lisbon to Madrid arrived too late.

The flight was on the time and everything was very smoothi

Asientos y tener espacio para maleta de mano y no tener que facturar

Pros: "You can always expect reliable and in time service with Avianca."
Cons: "Outdated aircraft, limited space."

My luggage got lost and until today there is no solution to the problem. It's still missing

I am writing to demand an immediate refund and compensation for the absolutely unacceptable experience I endured with VUELING this week. On Monday, my flight was canceled, and despite this, I have yet to receive any refund. I was then taken to a hotel in a terrible location, where no food or even water was provided. The next day, I was rebooked on another flight, for which I had to personally cover an additional €50 in transportation costs—only to have that flight canceled as well. After waiting 10 hours, only 10 of us were offered alternative accommodations, while the rest were left stranded. We were forced to remain in this situation until Thursday without a single explanation or proper assistance. During this entire ordeal, we were only provided with breakfast and dinner, while being charged extra for drinks. This level of treatment is completely unacceptable. I expect an immediate refund for the cancelled flights and full compensation for the inconvenience, additional expenses, and the significant distress caused.

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

Nothing. There was no flight. They cancelled the flight with no replacement about 9 hours before takeoff.

The flight was canceled at the last minute. Alternative flight was booked after 6 hours wait in Malaga airport.

Boarding with some sense and communication. It was a total free-for-all everyone coming all at once, no organisation of row numbers or priority.

Horrible, flight cancelled and had to come back the next day

Terrible. For clarity - this was the Level flight to Boston. Not Vueling. Would urge customers to avoid this airline. Gate agent was singularly unhelpful. He was argumentative, rude and went out of his way to ensure that every penny was collected for the baggage (which we realized given how early we were for flight we could have saved hundreds of dollars if we checked in on app). No onboard entertainment or WiFi. Half of the front section was empty because the seats did not work! Plane was falling apart.

No complimentary snacks, but I think that’s a standard in the USA. There were loud drunk Germans sitting in front of us.

My Aer Lingus flight (booking ref # 2SU4LF) was the worst travel experience I have ever dealt with. My flight from Paris to Dublin was delayed by over 2 hours which caused me to miss my connecting flight back to the US. I was not able to be rebooked on a new flight for another 3 days. When I finally made it on my rescheduled flight, it was delayed AGAIN, causing me to miss my connecting flight from New York to Boston. At this point I decided to just rent a car since the next flight I would have been able to get in wasn’t for another 5 hours. It was a complete nightmare experience and I will never fly Aer Lingus again. I have requested a refund from the booking company I placed my order with.

They couldn't do through check-in for us. They took 2 hours to issue just one leg of the boarding pass. They had no idea to handle the case of passengers who travels to USA via Dublin airport. we had tough time time Dublin airport as boarding pass for the US flight was not pre-issued. Hope Aer Lingus will learn to handle such cases which they couldn't learn in in the past 50 years of the service.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

Both flights late. Almost missed connecting flight and flight staff not willing to help expedite us off the plane.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

We couldn't talk to aer lingus we had issues with the flight change and aer lingus made us talk to kayak

Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

Probably my favorite airline and way to go to Europe. Everything went smoothly! Food was tasty, crew was pleasant. Really cannot complain!

Golf Bags never made it on the flight. Very expensive golf bag and. Clubs,shoes, clothing. Will file a claim against Aer Lingus

At Barcelona, you have to get your passports checked before going to the E gates so give yourself time for that. The restaurants around the D and E gates are really limited compared to prior to passport control. On boarding, the gate staff tried to charge me EUR100 for my carryon, saying it was too big. I put it in their ‘measurement box’ and it fit with the top slightly protruding where the handle was. The gate staff then said my bag was ok to carry and put an ‘approved’ tag on my bag. I was bussed to the plane I boarded a ‘Level’ carrier which I had not heard of before. If you booked through a code share like American, you will be served food and alcohol on the plane. They do not provide complimentary ear phones or blankets. The internet was free but only for texting. WhatsApp worked but Spotify did not. Entertainment choice was adequate, movies were old and selection was limited. On arrival at LAX, my checked in bag was damaged as the wheel was broken. I am taking this up with Iberia. Their website and customer service was moderate in terms of user friendliness. You have to have all your documents and prepared to be patient and persistent. Let’s see how this goes. All n all, for the price I paid, I would recommend Level.

Excellent with no delays and according to the time schedule.

Its a bus taking you on and off the plane so if you have big luggage … more muscles needed

Flight LIN MAD. Checkin was fine (but I must admit that being a Platinum member I skip the lines). Security was fine (they have the new machines where you need not take laptops or liquids out). Longe was OK (BA). Boarding was a mess, the boarding gate personnel were rude and some should simply not be in a customer facing position. Flight in itself was fine, usual Iberia European coach. We were on time and actually time to deliver luggage was better than normal for Barajas

Bad business class. Staff totally not helping. Lights and chargers not working

Great food, excellent service. Did not manage to make wifi work but in a flight of less than an hour it was not a big deal

Very well, except that my luggage didn’t arrive in the corresponding flight, but they brought to me the next day.

Was very unhappy with the entire process, from check in to boarding to the comfort of the flight. Did not enjoy the flight on Level.

The boarding was a nightmare. Iberia would not let me check in in advance. They then refused to issue a boarding pass in Paris and said I would get the boarding pass in Madrid. In Madrid, there was no transit desk, no help. I had to run around and find someone to issue the pass. I only had an hour and risked missing the connection. Only at the gate did Iberia tell me they were overbooked and had downgraded me. I was stressed, exhausted, almost missed the connection because of Iberia’s conduct. Unacceptable.

When having a connection at Madrid, it’s extremely confusing. You must travel from your arrival gate, all the way down stairs to a security check point, go up stairs, then downstairs to another security check. Then make your way to your gate. All the while traveling through a “mall” inside the airport which makes it difficult. 10/10 don’t recommend connecting flights through Madrid.
