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

It is just fine but I am okat withi it is because for a 30$ flight I didn't expect anything more.

Negative. Food was awful, seat broken, flight was late, baggage lost and damaged

The person at the checkin was very helpful. We couldn’t check in through the keyosk, but the agent was very helpful.

Everything went as expected. Luggage arrived at my same destination and nothing disturbed my vacation.

Flight being delayed for 35 minutes had me lose the connection to my transport

Our flight was delayed an hour and take-off was also delayed. Then our luggage was misplaced upon arrival causing a lot of stress snd more delays. We arrived at the hotel almost 5 hours later than anticipated and had to cancel our plans for the day. Overall a very bad experience. We will not travel with Portugalia in the future.

We Boarded the plane in the middle of the airport field . We were shuttled and climbed up the stairs, to board the plane,

Delayed takeoff was inconvenient. We should have boardrd later. Coffee/ beverage service on a 7:30 flight would have been good.

Flight from Lisbon to Barcelona was ok. Business flight Boston to Lisbon was awful. Attendants should pay more attention to Business Passengers and not be so stingy with water. Worse Business Flight I have ever taken. Food was awful. Cramped for space.

Disastrous boarding. Entered air bridge only to descend stairs and enter a bus. Plane had insufficient storage, was old and chair recline was damaged. Air stewardess was sullen.

The flight crew was good, the flight itself was quick and comfortable

My long-haul flight experience with this airline was not very pleasant. Earphones were paid, and no eye mask or other amenities were provided. The meals were served in cardboard boxes with plastic cutlery. The restroom was unclean and ran out of toilet paper. However, the boarding process was smooth and well organized.

I flew in business a couple of months ago, it was great, tried again in economy, it is the cramped seat I have ever been into, for an overseas flight across the atlantic it is inhumane to put passengers in such cramped space. Other than that, everything ok. Took a second flight from Madrid to London, also economy and it was roomy and perfect.

I was not allowed to cancel the flight, customer service is atrocious

Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

My luggage is lost and nowhere to be found, no response from airline

Boarding was a shitshow. Had to bus to the gate. No separate bus and boarding process for Business Class.

Sitting space was very tight, so eating was difficult. But everything else was good.

Need to pay for a cup of water. No food. Need to pay for headsets.

Issues with plane led to multiple gate changes and chaos. Very little communication from the ground crew led to cranky passengers.

Probably will never use this air line again. Rude miserable staff. Uncomfortable seats.

Enough seat availability for us to move a little and so sit together - but the flight was half an hour late

Ryan air is a scamming airline. They advertise that you have to follow they baggage policy and their employees just do whatever they feel like. My most recent flight, i checked to large bags and just paid for 3 cabin bags and priority. Apparently, according to the staff, they knew the plane had too full in the cabin. This meant they had to target a select number of bags to into the hold. Now, a normal airline just offers to take your bag at the gate for you, it is their mistake. Not Ryan air, they just tell you the wheel of your bag sticks out 2 cm, we will charge you almost what you paid to check your entire luggage immediately, then tell you it’s on you. I would have gladly paid to check in the bags in the bag check in, where they told me the bag was good to go. Never using this airline again. I used to enjoy the quick direct flights but I will never use them again.

I didn't eat any food so can't comment on that. The prices on the plane are extortionate (as are all prices on planes). Everything else was seemless and a great experience

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

Waiting outside for a long time is not really necessary

The baggage wasnt uploaded to the plane, lost baggage handling is very poor.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

On time arrival but the aircraft had seen better days and needed a deep clean.

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

Bag check in was terrible. Arrived 2 hours and 10 minutes ahead of required time and then waited 50 minutes in line to check ONE bag. There were 4 employees standing around as only two were checking bags and there were 6 gates available to check bags. Process is terrible. Lack of customer concern and service.

There was no useful information given regarding the flight back to the UK from Tenerife. This despite the week publicised problems around the EES system and the delays caused to boarding. This aspect of the customer experience could have been much better.

Good news was that Bag Check was open two and a half hours before the flight, which is essential with the chaotic immigration process. Flight was okay, but sitting at the back of the aircraft, 3 overhead bins on both sides were filled with crew bags and other misc items, so we couldn't put our cabin bags anywhere near us. To add insult, twice the crew managed to drop items that they were taking out of the overhead bins onto my wife's head, who was sitting in an aisle seat.

The true is that travel from London to Faro on 11/12/2025 by BA was cancelled, so I did not go to Faro, so i did not board easy flight. The mediocre qualification to you was because even when i bought an insurance, i could not change date neither obtain reimbursement. It could be ideal if you do something in order for me not to lose the purchase Thank you

Liked. The check-in was pretty quick as they had 5 desks working.

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.

Well Is extra charge for everything and other companies include that and the price.

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.

The communication about the delay could have been better before and during the flight. Also, this online form could have less bugs. It is almost impossible to type in this window.

Comfort isn’t a word one uses on economy airlines! Boarding was okay, delayed but okay, the flight was good, quick and time was made up.
