Whole way through - far more professional and slick than I expected

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.

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

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.

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".

Generally a good experience except for boarding in Naples on the flight back to London. We were all standing around for at least 20 minutes maybe longer as there was no seating.

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

BA Canceled this flight and put us on a flight leaving Aberdeen at 8:00 PM, delaying our return to the states by a full day. The cancellation caused us expenses in both Aberdeen and London and BA was completely unhelpful on the phone and at the airport.

The crew on the flight were not particularly pleasant and fluid restriction was an issue. I was not allowed to fill my water bottle. Crew didn't check on passengers other than meal service.

Entertainment system didn't work well. Also no new movies and limited choice of other programmes. . And only one USB A charger option. Most modern electronic items needs USB C. Planes should offer both

The space in the seat was okay, the staff were friendly, the entertainment system, my touch screen was not working and some of the films listed on the website for the flight were not available.

Big queues on arrival at airport despite having already checked in and only needed to drop bags off. Flight delayed which impacted on connecting flight.

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

Flight was excellent, staff was great. My first time in first class and it was very relaxing and comfortable.

They are disorganized….show your flight info half an hour before take off, so you are running all over the place. Customer personnel are not helpful, and act like you are bothering them when you asked for assistance - very rude!!! My very first and last time flying with British airways… good thing we have other options.

There was no entertainment offered or expected, so please disregard my readings of that component. The flight was fantastic. Efficient boarding, takeoff, and even early arrival!

2 hour delay with very little information given. Horrible service by BA employees at Heathrow after we missed our connecting flight. Extremely disappointing experience!

The flight was delayed by a bird strike. We were held in boarding area with no toilet facilities.

Very late to leave, poor communication on expected departure time and when boarding actually started.

Everything was perfectly fine, it’s exactly what you would hope for from a budget airline. You get what it says on the tin, what more could you ask for?

Boarding was started early and we were lined up in. A glass tunnel on the tarmac we were left standing there for an hour with no information the flight left and arrived 30 mins late

Need more check in desks at Marrakech. Even if you are travelling with hand luggage only, you still need to 'check in' to get the old style boarding pass. Unfortunately they haven't thought to separate out the people checking in luggage to a separate desk. Flight was delayed leaving but arrived on time. Limited food options on board and very overpriced.

Flight was delayed so long we missed our second flight. Entire trip had to be cancelled. Ryanair refused to help us.

Stanton airport is outdated, pure equiped, airport. Fire alarms, power outages is a common routine, wich result ir flights delay , additional money spending and huge gathering of people in airport wich is unsafe.

Boarding was like being hoarded like cattle, all penned in in an area way to small

I missed the flight from Manchester to Dublin because of poor informations from Aer Lingus and the airport, no possibility to check in online, they don't respond to phone calls, I had to buy another tickets to enable me travel to Dublin from Manchester. I want my money to refund.

Rude check in staff. Split family up with young children.
