I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Terrible last row seats many seats available but no offer to move to better seat

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

Klm start boarding while somw air issue in the plan

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

You should not have to pay for WiFi in business class

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".

Would not advise EasyJet for a 5 hour flight…small plane and hence a lot of turbulence. No inflight entertainment so struggle to pass time in cramped seats. We also fell victim to extra charge for our cabin bags, although bag dimensions were ok, but the handle was rigid and slightly fell outside their testing cage!!….never again will we fly with this airline and be party to their scams for making money!

The food and so are to expensive and old . Crew whas not very friendly . Apparently some other passenger can just Push through the waiting people to board while almost punching me and a father with a child down the stairs. Its always something with easy jet . The seats of row 26 where lose . And for a guy of my size there is absolutely no leg room at all .

Nice to fly out of Orly smaller easier to navigate airport. Being able to receive boarding pass well in advance of trip was comforting to know all travel was in order.

Liked. The check-in was pretty quick as they had 5 desks working.

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.

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

The food from Delhi to Frankfurt went bad or something cause I got sick after I ate the meal and felt ill the rest of my travel back to NY

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.

We just made it to our connecting flight. A long, long speed walk!

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

The plane was late (as was my flight out from Birmingham the day before)

It was good service. The very low economic seats where not comfortable

They gave us chocolates twice (for whoever would like an extra chocolate - kids did!). I asked for an extra water, and I was given one. Crew was very friendly!

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

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

Entertainment devices on A380 need to be fixed, the seats might do with updates.

I like everything about British Airways. Excellence. Perfect. Exquisite service.

The plane was dirty the food was awful and the boarding process took too long

Very efficient boarding. Plane lready for take ooff10 minutes before time.

Great crew. Seats do not recline :( but it is budget so i should have known. Otherwise comfy leather chair. Slight slim chair but again budget so expected. No entertainment do makes journey boring. Recommend packing plenty of snacks and games or download plenty of films and music in your device. Staff excellent. Clean flight. On time.

Both of my flights had issues with their time slot with air traffic control, so they left over an hour late and the flight back to London was delayed by over an hour. Please provide more clarity about baggage requirements on booking sites, your website and within the app. I had to pay for extra bags at the airport when departing London, because they didn’t specify that your carry on bag can only be a backpack and not a trolley, my trolley bag fit the size requirements of the backpack but still I was made to pay

The crew at Check-in was very helpful. It’s was appreciate.

It’s a budget airline. You get what you pay for. They insisted on getting us out of the gate and into our slot on time. They got us to the destination safely. Aircraft was clean and well maintained. What more could we want

Half an hour delay. Squeezed into a small Departure Lounge with very few seats. Noisy flight with screaming unruly kids. Loud IPads and Phones. Heaven!

Were delayed in the airport for 5 hours with no explanation. Flight kept getting delayed by an hour at a time and wizz air staff were no where to be found

The flight was delayed 5 hours and I'm and invalid,I wan a refund for this

The cabin crew on that flight were super fantastic and super helpful. They were so polite and considerate that i felt i travelled with a 5star airline.

Delayed delayed delayed - always with Wizzair. Staff were friendly and well mannered but clearly the company is unorganized and the aircrafts are outdated.
