The crew was great. There was a big guy sitting next to me who was hanging over my side of the armrest the entire time. Maybe some information about "Be considerate of your neighbors, this is tight space, be kind". The breakfast sandwich was not appealing at all.

The crew was great. There was a big guy sitting next to me who was hanging over my side of the armrest the entire time. Maybe some information about "Be considerate of your neighbors, this is tight space, be kind". The breakfast sandwich was not appealing at all.

Kayak let me choose these flights on TAP but then after 2 months, cancelled my flights because they didn't think 90 minutes was enough time for the connection. I notice that neither flight was actually cancelled. Just my reservation. Why let me go through all of that effort to find the right flights for us, only to cancel it from underneath us 2 months later leaving us scrambling to find an alternative?

It was a good experience overall. We were however delayed by over 3 hours due to a security issue with one of the passengers inadvertently leaving a power bank in a luggage she was using as carrying on but then had to be moved int check in due to spacing issues. The airline staff had requested that she checked her bags in, but should have reminded her about removing all hazardous material like her power bank. When she eventually remembered as we were on the plane, we had to turn back and go through security all over again. Hence delaying our takeoff. The incident could have been prevented if staff reminded these passengers to remove their power banks.

this flight was awful from pre-boarding to on the plane. There needs to be more coordination between TAP and My Way. We were in first class and I am handicapped. BY the time we got on the plane there was no place for our baggage and the crew did not handle the situation well. They gave us an argument and said that we'd have to have it checked. Then, after I complained they moved some people's bags to put our small carry ons several seats back of our seats which were in Row 4.

Bad. They gave me a voucher for food to use at the airport but didn’t have time since I had to catch the other plane. No refunds and lack of communication

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

The ground staff did not load my bag onto the plane and despite me watching from the bus that my bag is not being loaded and taken back on the cart to the terminal, I pointed out to the staff and ge laughed upon checking my tag and knowing they made a mistake. Instead of calling the cart back and loading it he said we can’t fo anything and you should file a report upon landing at RAK. I told them my stay there is short and i needed my bag as it had everything I needed but no avail. Even the pilot was informed, staff of the plane was aware but all in don’t care mode. Upon arriving at Marrakech RAK, i filed a report and being told it might come in next flight tomorrow and we don’t provide delivery service, you must come and pick it up. If it doesn’t arrive on time then it will be sent to your home in the US. Unbelievable stress and inconvenience that could have been easily prevented by the ground staff.

The cabin crew were curt, not with me, but observed with other passengers. They were unduly rude and it was unprovoked and when they realized they were wrong, they made no attempt to apologize for their own confusion.

I was disappointed of the crew, not friendly and attentive. Delay one way for fuel leakage and the plane is so hot. Not that great all around but I’m glad I experienced it so now know better.

Flew Business class and did not like anything, flight attendants were rude and not helpful. Food was of poor quality and I did not eat meals.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

Guide passenger if fhey board from front or back door cause it was a total mess

Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

Rubbish moved my seat don’t know why same seat configuration cost me extra so me and my wife could sit together now I know why no paper ticket so they can do this

Slow and delayed boarding, including standing outside 15m in -3 temperatures, Late take-off approx 45 mins Very slow bag delivery approx 45 min - no explanation

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

Flying from Newquay was an absolute dream! Would 100% recommend flights from there!

It would have been better if I was not ill so I didn't go and I didn't come back and I could not transfer my tickets to a later date as Ryanair stop flying from Manchester at the end of October till next year

Passengers next to me insisted I change seats so they could sit together. I had to frequently move so that when the sear belt sign was on I was in my proper seat! I was returning from helping my mum with my dad's things after his sudden death and didn't feel like arguing with the other passengers.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

You need to make signage at Berlin Airport clearer. Having checked in online we had our boarding passes onlour phones. You do not make it clear that you need to check in again to receive a printed luggage tag. You get to baggage drop off and it says you can only do it with a luggage tag BUT not how to get this.

It was good except they could offer free water and tea/coffe

Sitting on the last row in between the aisle and a massive person, all people going to the bathroom bumped into me including the flight attendants.

Sat at rear of aircraft and was very cold. As a frequent flyer for many years, this is was the coldest I have ever been. Other passengers and some crew were complaining how cold it was. Sitting near the doors always risks being colder, just the way the aircraft works - but this was exceptional, bring a good jumper. Everything else was pretty standard easyJet - good value low cost carrier.

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

Boarding and disembarking were smooth. Not offering free water was cheap ... I've never encountered that before on a flight.

Boarding could be better. To get through your gate but to be stood in a corridor for 20 minutes is not great.

The plane was postponed for over 2.5 hours, which meant that all four of us missed the check in time for our ongoing trip to Melbourne. We had to buy new tickets for 4 people as we had to forfeit the ones we had. The cost was really unfair. i understand that it was snowing during the first leg of the plane for that morning. Surely the cost could have been shared by the airline and not all by us. I could have bought insurance - but you can see how much I travel. I will need to chose more trustworthy airlines.

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

Queuing for quite a while despite using the "speedy boarding".

The staff was extremely friendly and nice. Overall, the flight was pleasant, and the food was good. They asked me to check in my smaller cabin luggage suitcase in Mumbai as the flight was full. Fortunately, I had packed a spare set of clothes in my laptop bag so I was okay.

Flight was delayed by over two hours and that meant my connecting flight was in jeopardy but there was no acknowledgement or help from the BA staff

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Business class on British Air with the Airbus 320 means the same seating as main cabin ( 3 - 3), but with the middle seat of each three-seat row blocked off to become a platform/table. This is decidedly NOT a business class experience. Other aspects of the flight were fine.

I Keep your expectations to low to middling with BA, or most European/ US airlines these days.

Wish the food and overall service was better. They treat Business class passengers same as economy

Old plane, sold out on snacks, just trashy seats..broken..etc

Good flight. Only negative was the bus journey from plane to the terminal. Didn’t exit t this either BA at T5

Nothing! They canceled our flight to Greece the morning we were supposed to leave and offered us another one 5 days later (for a 9 day trip). They said it was an “operational decision”! Yeah a 777 that was 2/3rds empty, so they probably sent it to the Middle East to make a fortune getting people out of there!!

WiFi wasn’t available to economy until the end of the flight.
