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

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.

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

sadly in Basel & Naples- no jetway we had to climb up and down stairs with our max size carry-on luggage, which was not fun!!!

This was our first time using them. I gave okay ratings for food and entertainment because it was minimal or not provided so I couldn't judge, but much better than most budget carriers we have ever used.

We were charged a ridiculous amount for a name spelling error on ticket which I would’ve corrected if I received pre-check info more than 1/2hr before flight. Then we were told at ticket counter that our bags were fine for boarding but then we’re charged another ridiculous amount to take in our luggage despite being told differently. Flight itself was great. Charges were unfair.

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Usual issues with flight delay. Perennial problem of travel by plane.

Straight forward checking as long as you have completed every single detail online, prior to checking day. Efficient boarding, seating is ok for a two hour flight. Fulfilledour travel requirements from Manchester to Marseille.

I couldn’t understand the aircraft tannoy announcements I was in seat 20C - nobody in our row could either. Speakers a bit too quiet plus messages read out too fast. Otherwise excellent flight. (Flight delayed by 50 mins)

Delayed and changed Multiple times after booking necessitating many. Travel changes ; a bit of an issue

I bought my flight, insurance etc early and paid over £200. But had i waited until closer the time the price was much cheaper, i appreciate that it could've been more expensive but it wasn't. A better discount for booking early would be better than your current one

ontime and super quick boarding and disembarking. I made it in 6 min from airplane through passport control to the train platformin Cologne. Amazingly quick airport.

They lost a bag and now our vacation is ruined

There plane had a technical pricken so we had to disembark, but the replacement aircraft was provided within one hour so there was not much delay.

Flight details on public information screen were misleading and wrong.

We were diverted to warsaw and there was zero information. We were just forced to disembark and off we go good luck the reat of the way. We all had to go our ways to find a way home!!!! Horrible horrible and it cost us alot of money to get a hotel and trains 4:30 pm next day.

Was very good the flight, 15 minutes late,but was very ok!!!😊👏

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

The flight was delayed by an hour. Made the connection uncomfortably tight.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

The flight attendants were rude in the DEL to FRA flight. The transfer between the two flights at Frankfurt International Airport was an unpleasant experience. The airplane was never parked at the terminal, but was deboarded instead on the tarmac itself. For those passengers in need of a wheelchair, it was a nightmare to come down the stairs and then rush across the airport to catch the connecting flight from FRA to IAH. Upon arriving at IAH, it was informed that the luggage had not arrived. Would make it a point never to travel with Lufthansa again.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Delayed over 2 hours. Bring your own snacks or prepare to pay. No entertainment and no plug plugs for charging.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

There is more space in this economy seat. It felt like a better layout, not so cramped.

I didn’t have food and they don’t include entertainment. Not much leg room at all. Staff were great.

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

Business class was nothing more than Economy with middle seat empty. Uncomfortable seat and leg room. A mom behind me had a 18 month/2 yr old on her lap, who had his feet on my back all the time- while middle seat remained empty. Pretty much not worth the fare. Very disappointed.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

charging port did not work, no entertainment system. Other than that the flight was good and safe.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

When Stephen arrived with our wheel chairs - we were in excellent hands! He was such great help with getting our rental car and then reporting our missing luggage. When you are exhausted from traveling for too many hours, he was just what we needed to navigate everything! Give that guy a raise!

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

Gate information deliberately delayed to only one hour B4 flight, lack of info finding gate.
