Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

Poor handling of carry on luggage. We had a 8 hour stop in Santiago, are over 70 and, in spite of paying full fare they wanted to send carry on to luggage hold. No empathy. We had to show that several group 4/5 passengers were not sending their carry ons before they finally let Is keep them. Very poor .

Boarding was confusing with a delayed flight because there was no English translation

entertainment was not good; the shoulder strap on Business class seat did not sit well across the body (more like across the neck); the food was not hot and the special meal promoted by insert in the menu was not available to us

We didn’t have any entertainment. I tried to go online without success. The airplane was extremely cold and they didn’t have blankets.

Although the flight is goof and the crew is good, the way the airline charges you for every service is ridiculous.

Plane never left the ground. Mech issues - entire trip was rerouted through united.

No entertainment but not expected. Unless you are referring to monitor that you can use. Then Al, was fine on all flights.

It’s been some time since I saw the plane and the cabin that old and worn out.

I loved how polite the crew was even though some of them wasn't the best with English that they still done everything they could to help me with my needs food was amazing

Let’s be honest. You know you are boarding a flight where the seats don’t recline and you need to pay double the price for bread, gin and water. But beware, they test your tolerance to torture pre boarding. They call all British passport holders. Then tag cabin luggage to be checked. And the ground staff pretend not to know what is happening and just says - please ask the other staff.

It poured rain, our luggage was sitting out in it uncovered on the transport cart while our plane was delayed! Nice business class plane for short flight to Lisbon, but more delay & rain in Lisbon, with terrible Business class seat with no entertainment & cold food on longer flight to London…ALL LUGGAGE AND CLOTHES INSIDE THEM WERE SOAKED THROUGH!!! Could only try with hair dryer to get some drying before quick turn round to train trip.

Menzies group staff not very sympathetic good at breaking up families during the boarding process

There was no warning that they have added passport control after check in, the line was enormous and after 46 mins wait we missed our flight. Were forced to leave the airport and purchase new tickets at full price to board a later flight. TAP were unsympathetic and unhelpful.

Check-in guidance for transfer flight, boarding, in-flight service, seat comfort, etc.

Not much to like. Check-in and bag drop procedures are a crowded, disorganized and confusing mess. Agents were grumpy and unhelpful, somehow expecting passengers to automatically know and understand the airline's procedures. Boarding was chaotic and included a stand-up, sardine-packed bus ride to a stairway pushed up to the aircraft out on the tarmac. Passengers were left waiting in the bus for a lengthy period on both ends. Flight departure and arrival were delayed by passengers scrambling to find space for bags in the overhead storage. Many passengers not in compliance with carry-on rules. Everything you could hate about flying in this ride.

Its a short flight with no entertainment. The food was so so.

Dreadful - queued to get onto a bus, stood for 10 minutes on the bus, drove to the plane, stood for another 25 minutes on the bus outside the plane. When allowed on we could only board from the front & were seated in the furthest row back. The second bus was allowed to board from the back so chaos ensued!. The flight was an hour late - nobody said why, nobody apologised. On arrival at Heathrow we stood for nearly 30 minutes before being allowed off - again with no explanation,

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

We upgraded to economy plus for the extra room and the seats weren’t any different from others. There was no foot rest nor extra leg room. Total waste of money.

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.

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

The crew was not kind , just doing their job but very cold people

I travel on a monthly basis and I’m not a stranger to budget airlines. I never complain about anything, it just about adjusting you expectations to what you paid for and you will get, but these flights (2) with Air Europa Miami - Madrid - Athens were a terrible experience. Both flights had a significant delays and multiple gate changes. At the checking they used a hand scale to weight your carry in, it cannot be more than 10 kg , even it fit on size.Luckily mine was ok . The food was inedible. The staff service was ok, but you can totally tell they do not care about much and show little customer service culture. I think this was my last trip on Air Europa. Actually the price was almost the same than other major airlines, I just took this one because I needed to depart late at night.

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

The flight, the staff and the airplane were all fantastic. I highly recommend.

Flights from MADRID to CARACAS and back Seats on the plane were too uncomfortable for a 9 hour trip, especially when the flight was completely full. Crew treated passengers as if we were cattle. Desperate rush to get food served so they could enjoy First class food at the back of the plane... I went twice to the back of the plane (no one answered the flight attendant button) to ask for coffee and was met with a very abrupt response... 'YOU HAVE TO PAY FOR IT'. The only thing staff could think of saying to me was 'la mascarilla senior!'.... In a way I do not blame Air Europa for getting away with this lamentable service, they are one of only two carriers flying between Spain and Venezuela so do not have any competition... I do not think they would dare offer the same service on a flight from London to Los Angeles!

I have loved the flight, very professional and caring staff.

I was upgraded to Busines Class from premium economy which was a great surprise. But......the service was not marginally better than premium economy. After the welcome on-board drink, I only saw a flight attendant twice...... when she delivered gluten free meals. In between, during a 8 hour flight, she didn't check back with me to offer water or collect trash. I had to fetch my own! The gluten free food was not good - they gave me the same meal whether I was in premium economy or business class.

My flight out of London was canceled on September 9. We could not get a flight to Italy until 2 days later. That means we would miss my son's wedding. So we had to take a train from Heathrow to central London (14 £ = $18.99). We then had to take the train from London to Paris (612£=$830.24). We had to take a taxi from the Paris train station to the Hotel Sixteen in Paris (€67.5=$78.67). Our hotel in Paris is (€340 = $396.26). Our flight from Paris to Italy was (€442.25=$515).

Boarding was offal, crew and jet old and most things were not working, food was terrible.

Staff was very attentive, from the counter staff to flight attendants. Food was not great.

Delayed departure, even more delayed arrival, 40+ min waiting on runway before going to gate - horrible Also didn’t get a single bottle of water all flight

Boarding going from seated area to standing outside and then boarding the stairway seemed unnecessary. Drop the standing outside part.

Check in at bcn was a nightmare. In-seat screen did not work, asked for help twice but was not able to use overhead light, watch the safety briefing, watch entertainment or monitor map

Over sold! Never again. Got bumped even though I checked in and arrived on time with all my documents in order. Wasn’t even offer food/drink voucher for the next flight that was 6 hours later.

The flight was canceled. It was very troubling because the rescheduled to Air France was two days later. I incurred two days extra of hotel, was not able to get a boarding pass until I reach the boarding desk at the airline. I don’t know what happened British Airways, but I was very disappointed.

There was a delay on departure. Seat configuration is horrible. BA should not fly this confirmation any longer until the new seat conjugation is installed. Your competition is beating you. Food was poor to average. Not many choices. Arrival was delayed at the gate due to another plane being at the gate. You would think after the delay at the departure, BA and ground control would figure out how to ensure you passengers wouldn’t be late and running to their next connection. Overall, BA continues to be very low on satisfaction. If I had an other choice, I would choose another airline.

We had to purchase an upgrade to get reclining seats. There was no entertainment module.

Seating was tight. Seats don't recline. Initial flight was cancelled. Lost two days of vacation.

I upgraded to businesses class. Because of that the flight was comfortable.

Provide free food and drinks on an international flight. Add updated head rests

The flight attendant smashed her beverage cart into my knee, causing significant amount of pain. The seats were extremely uncomfortable. No food or drink is offered unless you want to pay the ridiculous prices for it. The schedule of flying in the overnight hours is also very uncomfortable.

why did we have to go through security mid flight

Worst airline , charge for everything even for water, seat space is very bad

Horrible. They canceled several flights and kept pushing us to different flights. We were 12 hours in the airport with no compensation and not even a single apology.

Seat space was terrible no food on a six hour flight

Voo longo nem mesmo água ou gelo é servido, se quiser tem que pagar. Embarque é péssimo, mau atendimento.
