12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

Terrible experience - we won’t be flying with Air Europa again

The insanely long lines at customs were chaotic and stressful. They also created a lot of stress among passengers. Including fights and threats. The hot food I purchased was cold, barely edible. The check in staff and crew were nice and the pilot good but the overall experience was very disappointing. Passengers were still insulting each other upon arrival.

No frills airlines. Tickets were reasonably priced for a short-term booking. But comfort is a big issue.

Food was terrible. No breakfast. Will not use this airline.

Well, I'm not too happy with the service a flight for 9 hours with only a cup of water or wine. Food only service you one-time I bind flights many different airlines and they make sure that you feel comfortable with the food and drink

i paid accidently for a second bag instead of a golf bag (Eur 40 instead of 50) they would give me credit when i tried to change the second bag from a regular suitcase to a golfbag. The comment was "you made a mistake, your problem"

Service on plane was appalling. Cabin crew did not want to help with anything. Window darkening screen did not work so we had to sit in the sun for a few hours until it went down. TV screen did not work and cabin crew just shrugged their shoulders and did not care. We waited for over 2 hours for headphones so we could try watch one screen between 2 people. We had to go to back of plane to request basic water as crew never responded to call request. Will be letting many others know to warn them off ever using Air Europa. Total disaster of their own making

Impossible to check in via the App. Kept on getting emails offering upgrade. When followed through not available. Wasn't any food anyway.

Place above head to place the rucksack in is smaller than in other planes, so it needed to be located under the front seat.

There was confusion over the electric wheelchair. Though it was categorized and double checked at checking the gate seemed confused by the chair.

Boarding was a mad rush as people still had issues with boarding passes and groups 3- 7 were asked to board when travelers were still stuck behind the document check. Food was one of the worst I’ve ever had in an Economy flight. The crew was very friendly though

We were delayed 2 hours because the crew was late. They need better planning by the crew, we had to sit in uncomfortable seats waiting for them.

Difficulty to check in online, but well handled at the airport. Flight delay was unfortunate. Crew was adequate but not what we have usually experienced from BA. Seat was not comfortable.

Good Poor. service onboard No food. Low quality for economy plus

There's not enough leg room in economy class. The seats are very narrow as well.

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

I’m very mad because I paid an extra $105 to change seats to an exit row with more leg room. The app clearly showed a gap in between the seats in the row I changed my seat to and I paid for it. When I boarded the plane, it wasn’t an exit row seat and no more room than my original seat. I feel like I was ripped off $105.

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

The boarding process was horrible. As a business class passenger I had to stay the long line after the gate doors because the was no special priority boarding. After the full of people bus stop near the plain nobody from the stuff was organize passengers on the ground before the plane. All passengers from economy class were using the first ramp and passing business class to rich their seats in economy class. But at the same time the second ramp to economy class seats was absolutely free. Bed selection of vine. At the beginning of dinner Cava was finished. The food was very simple for business class and not tasty. It is impossible to serve grilled beef in bouillon instead of creamy souse. Instead of espresso I got filtered coffee from the pot. Second meal during 12,5 hours flight as a small piece of tortilla is too small.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

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

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.

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

It was timely boarding, well organized. The food was weird in a flight to Buenos Aires. I felt as if I were flying to Asia because of the chicken teriyaki. In my section flight attendants spoke only German and English. I wondered why no Spanish speaker was hired for a flight to Latam. In that Lufthansa needs to be more customer oriented. Compared to other airlines the four seat in the middle is less comfortable. That said, staff was polite and efficient, the entertainment system worked well. It was ultimately a peaceful, well organized and safe flight. Thank you !

Seats were comfortable with plenty of luggage storage and legroom.

Caos en el aeropuerto, nadie sabe donde se va a sentar, reasignan asientos a último momento, no respetan que se haya elegido asiento con anticipación incluso pagado un asiento de mejor categoría , el personal fue muy amable

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

Seats are absolutely not comfortable and large enough. There’s a limit and you stepped over it. I understand that there’s a business class, however for the price it costs, it’s just plain stupid for a 50 minute flight.

Last seat of Bussines Class it does recline but passenger seating behind kept pushing since they did not have space once my seat was reclined

No food, terms when selling are not clear. To pricy for the service in general

A few years ago long flights 6 hours or so used to have video screens and they offered ear phones. The food cart used to come and drinks. Now absolutely nothing. Avianca is as bad as Spirit Airlines. Avianca will now be my last choice when booking my next flight.

Flew with our two children. Paid $380 to check two bags (one was overweight). They then left the bags behind on Sunday, December 21st, with all our family’s clothes and family Christmas presents. When we arrived at our destination they told us the bags had not arrived, and they thought (but didn’t know) they were still in Boston, but that there’d be a flight the next day and the bags would arrive the next day. The next day we found out there was no flight, now we’re hoping we get our bags before we fly back out. Meanwhile, trying to get any engagement or accurate information is a waste of time. The folks at the call center are just gatekeepers, who can’t connect with any departments that actually do things to solve a problem. Getting information is made deliberately difficult. My biggest regret is that I’ve had a number of awful experiences with Avianca traveling between the US and Colombia, and still let myself get suckered into buying these tickets because the schedule was great. Never again.

So so, you feel like you have to pay for everything each time

They charged for WATER on a SIX hour flight!! never again!

The temperature was cold and the food that we had to pay for was awful. The crew didn’t even offer a free glass of water. It was a long, expensive and uncomfortable flight.

My international flight from LAX to Argentina had one free check in bag included in the price I paid, however your crew in LAX made me pay $95 USD to carry it on! Please note I had only on small size luggage (carry on size) and one backpack. I demand my $95 USD back that you guys charged me illegally in LAX.

The flight was overbooked and the solution gave was unrespctful. I arrived 4 hour in advance in the airport and only after 2hous was possible suggest a different ticket with another company LATAM, I have accepted, but when I was checking in at LATAM the tickets was issued without luggage, what it is absurd since I have bought my tickets including it since the beginning. Due to the timing for the next flight was not possible return to Avianca to claim due to the distance between Both companies Avianca and Latam since were located in different terminals. I have insiste to the crew of Latam to call Avianca to solve it, but they could help they were alleging that only paying a thousand pesos Mexicans ($1,000 MXN) to dispatch my luggage would be accepted and I have no money at all. So I had to beg for others passagens, it was an humiliating to exchange luggage with who was platinum in order to return back the luggage in the connection airport in Brazil (GRU). I have no clue that a judicial process would be taken from my side due the lots of stress in sequence by the non professional treatment with a passenger that was just following everything said by Avianca.. Long hours of waiting until next flight and only arrive at final destine in 6hs later..
