I suspect that there was an item pilfered from my bag at the TAP automated check-in counter on March 26th at Heathrow Airport around 11:30am. I think that the employee assisting me with my bags took something out of it when I was not paying attention because today, March 27th there is a notebook missing. Please check the camera to see if indeed this occurred. My description: Male, African Decent, 5'8, 180lbs medium build, wearing trousers and a jacket. Employee description: Female, Indian Decent (guessing) 5'7, slight build. Flight 1359, London to Lisbon.

Perfect although it took an hour to board the plane but other than that it was great

Ground staff at Rome gate & boarding were rude and unhelpful

The quality of the aircraft and the professionalism of TAP's staff were perfect. The quality of vegan meals can be hit or miss depending on the airline and the city of departure; on this flight, our vegan meals were quite good. The boarding process for the connecting flight in Lisbon could have been organized a bit better, but it did not spoil our overall experience with TAP, which was excellent. I'd definitely recommend TAP to others.

We liked the crew. They were competent, professional and friendly. The only big negative was our departure was delayed several times and the airport staff did not communicate what the problems were and what we should expect.

Great staff who were ready working with smile 6 in the morning on New Year’s Day. Although security checkpoint was way too busy, the airline staff were understanding and waited few minutes after boarding. We took off not only exactly on time, but arrived 20 minutes early. Two thumbs up!!!

The flight was good, but not entertainment or free food or drinks were offered.

Flight was delayed and there was no wifi on board. Flight attendants could not or did not want to reser the wifi. Not acceptable.

Airline attendant never walks along the isle to check if everyone is ok. The food is worst I’ve experienced. Chicken pasta is very salty while the fish is bland and over-cooked. Only two toilets for the entire economy section.

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'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

I paid a lot of money for seat selection and was miserable for flight duration

Lufthansa lost our luggage. After a lot of chasing on our part we got it back. The main problem is that there was no office in Bogota to help us outside of flighttimes. The customer service phone lines had no data on our luggage. I think Lufthansa need to invest in managing communications over lost luggage or this will end with everyone taking more luggage out of hold.

Very good service. One of my journey was by bus. But they advised by plane. Wrong information

No entertainment, no food or beverage included… Price like Lufthansa, “comfort and service” from Eurowings.

Flight comfort was good. However, due to delayed flight, waiting was too much while boarding. Moreover, food choices can be improved as well.

Not available crew to load the luggage for all the passengers,comon situation for local European destinations , not acceptable situation, never Lufthansa again 😉 🙄

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

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.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

Boarding great. Didn’t eat or drink so can not comment.

3 hours delayed Don’t understand why when you have paid for ‘speedy boarding’ they call you forward to then make you stand fir another 20 minutes in a confined space before boarding the plane.

The pilot did everything possible to make up the 35 minute delay. His communications were honest, prompt and positive throughout.

Delayed and ketone runway. Was told some nonsense about thunderstorms slowing down flights. Why not just come out and tell customers NATO and BRITISH FORCES were doing defence exercises and were in control of AIR SPACE.

Would have liked the plane to leave on time so I didn’t miss connection upon arrival. Some pathetic excuse as to late departure bought about by easyJet incompetence

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

Staff were friendly and flight was on time. Free drink and snacks would have been appreciated.

Booked through you used Kiwi who did not complete checking in until 24 hrs before departure when the check in was available 48 hrs before hence we sat separately. I will not be using you again.

Pros: "Quick boarding and arrived early."
Cons: "The seat was very very small for an average size human and the seat belt was on max.. No social distancing between seats"
Pros: "Rate. Didn’t like the charge of 55 pounds when I couldn’t check in on my phone. But the person at the desk was pleasant."
Pros: "Bought a seat 3 hours before check in and had a row to myself"
Cons: "Excellent Ryanair flight. 75% full. Very friendly crew."

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

This was a late night flight but the lights was on all the time and kids were screaming and many people were so loud. I was expecting to have a little rest on the plane considering it is late night but this way I couldn't. I think if at least the light would've been off / lower then people could feel they should be quieter.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

I didn’t get to London or Amsterdam. They lost my connection flight . I was stuck in Madrid and they rerouted my flight to Austria where my son had to come and pick me up. To get to my destination and they lost my luggage and they’ve told me they can not find it very poor service so have no word for what happened

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.

Overall good, but the fact that there was no WiFi was a big deal for me. I am not used to having no WiFi during long flights. I always fly Delta-KLM and they never have had an issue with WiFi.

I asked for a wheelchair. I have a back health condition. I had to walk a lot

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

Boarding = No one respected the boarding groups. The ground crew did nothing to enforce the boarding system. What is the point of being a Gold member when there are no benefits to that? Tired old plane

Almost 3 hour delay. First because the crew was late. Then a technical problem with the airplane.
