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

Very quick flight, efficient boarding, and clear and thorough instructions and attention from staff.

Amazing, not too crowded, great temp and the meal was good

The crew was good. The flight was not overly crowded so we had some additional space.

First time flying airline. Great experience. Clean plane, comfortable seating, great service.

They lost my bag so that is unfortunate.. still waiting for it

Didn’t have requested food and seats could be more comfortable.

Flight attendants on this flight were very lovely. Hot food was terrible. Canned wine felt elevated and was GOOD. The aircraft was overall not very clean. Although this one was much more cleanly than the flight from Pisa. Pilots were great & landings felt smooth and safe. As I mentioned in my last review, this was my first time flying aer Lingus in many years and I cannot say I will be rushing to book again. This airline needs a real facelift.

Everything went extremely smoothly! They boarded by groupings of seat numbers starting from back to front. All staff very helpful and accommodating. Food and beverage plentiful and good.

The plane from Venice to Dublin ran out of food. They did not restock the plane in Venice.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Long wait for the stairs, the bus to disembark from the plane, and the shuttle to the terminal.

Was a really good flight and so fast always try to get the first 5 road if you can

Almost as usual, half an hour take off dilay, on the other hand - the checked in baggage arrived as magic super quickly. By the way - why do you ask to rate the food and entertainment on flights without them? at least offer the option of "Not Relevant" or similar...

Comfy seats, great cabin service and a very relaxed experience

Basic service for the basic price. Efficient and cost effective, so ticked all the right boxes.

To complex. So many types of fare. This made the boarding a caos.

Needs faster boarding procedure. Not their fault but should still take into account indifferent flyers.

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

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

The plane got delayed, ground staff communications were dreadful, process to get on the plane was amateur, sitting in the plane for ages before takeoff is avoidable… will not chose that flight ever again.

Everything was on time and easy. Food in business class was great. There was no entertainment on board, though with business class you could get free internet, but so spotty it wasn't worthwhile.

They could have provided more than a premade mass produced tina sandwich for a 10 hour delay and/or had something available on oars other than potat chips once we boarded. They also could have not lost our luggage. Or barring that, at least foled a claim for us once we landed. Instead all of those things happened and they told us if we wanted to file a claim to do so online. I laid for business class for both of us. What an incredible waste of money.

We were bumped out of bulkhead seats we purchased a year ago. We were moved to row 5 and the folks in row 4 fully reclined making it difficult to get out to use the restroom. The seat have too little padding making them uncomfortable 3 hours into the flight. The movies did not offer closed captioning and the earbuds were poor so the entertainment was mostly unusable. The food was just passable. I would not fly Iberia/level again. Iberia also bumped us off our direct return flight so I would say the whole experience with this airline is poor.

The flight was operated by level, who had a sister’s check in procedure (2 hours) due to understaffing and a computer malfunction. While 3 agents stood at the business check in, with a total of maybe one actual customer there at a time, a huge line formed at economy check in with only 1 agent staffing the check in. Then, my luggage was lost - a guitar case with contents inside valued at 3,000 USD. The computer system of LEVEL could not locate my bag and had no record of it, and IBERIA (with whom I purchased my ticket and the checked bag) refused to help. It was a disastrous experience and I will never book Iberia again

Without any prior warning, I was seated in a row just in front of an exit row (27F), and I had no idea that my seat would not recline. However, the person in front of me did recline her seat, reducing my space. And because I could't recline to regain some space, it was my WORST flight ever.

Terrible boarding procedures in Madrid. The airplane barely has any legroom and I am 68 inches.

Not bad but they lost 2 of my bags when I got to Florence

Couldn’t get boarding passes online, delayed an hour, and smallest amount of space on board I’ve ever encountered for such a long flight.

Flight was delayed by well over an hour. Communication was terrible.

We loved our flight crew were lovely and we were comfortable.

Had a lovely flight arrived 25 minutes early food was good staff we lovely.

The check in was horrible. They randomly took my bags and charged me more. I won’t fly if I can help it again.

Did not enjoy this airlines. Charged for things they should not have. No room for comfortable seating. Charges for water!

Boarded and sat on plane for 3.5 hours before taking off, Updates infrequent and no refreshments offered.

I didn't have food, and there was no entertainment as it was a short haul flight, so can't comment on those, The head cabin crew member was addressing the passengers like a telesales person reeling off terms and conditions; we didn't understand a word he was saying. This is the second time this year we have flown with Ryanair, and both times we've had to carry our luggage downstairs to walk to the plane. As were both OAP's this isn't really acceptable. We have another flight booked for September to Lanzarote, so hopefully that will be better.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

The punctuality of f the flight was super: we left on time and arrived about 20 minutes early - and the cabin crew were both friendly and efficient. The only downside was that Ryanair appears to have resumes its old obsession with sizing cabin bags again after a long and welcome absence.

I liked nothing. An extremely uncomfortable flight, staff were rude, no ice for my drink. 4 hours of misery

Boarding was chaotic, the gate changed 4 times and we took off 1 hour late
