I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The flights were on time and the crew was friendly and helpful. The food was ok. The seats were quite cramped and if the seat in front was tipped back there was very very little room. The entertainment was only on your own device and there was no usb charging

Boarding and staff were excellent. The food was ok. Very cramped seating. No existent entertainment other than on iPhone over wifi with poor choices of movie or shows. Bring your own entertainment. Nowhere to charge your phone

Delay was not properly communicated. Service, plane, value of ticker were all great.

Excellent service and food in the Club Class. Warmly recommend. Much better than AC.

My new suitcase got busted when I arrived at Toronto , two of the wheels are broken and can no longer be used , I am very disappointed over this situation but the flight and service was awesome .

From what I saw there was no entertainment. Similar to my flight to London, I personally would like the attendants to be more interactive during the flight.

flight was delayed and stewards were preoccupied and not helping passengers. The pilot was very communicative which was great. The window was dirty as were the back of the front seats with chewed gum and slime on it. I hope this helps.

Traveling on two legs the food was identical and not very good

Flight diverted but info was really poor, ev3n with airport staff. The cats desi was a km away ,

We are experiencing more delays with westjet than other companies. West jet used to be our favorite airline.

Require more comfortable seats. More frequent water/beverage service. I would like better food choices. Overall, very mediocre. I now only fly WestJet when there are no other schedule options - no longer my first choice.

Excellent and a surprise as I had never heard of it before.

Agent checking me in was great. Plane was nice. Problem was with the handling of my fragile check in. They damaged my steel drum, waiting to hear back from them to see if they will take any responsibility. Think twice about travelling with something fragile, they don't seem to treat it any different than normal luggage

The flight was on time and shorter time arrival than planned. I was an ultra basic passenger and understood one personal item on the plane. The announcements of one personal item and zone 9 boarding certainly felt like we were separated from the rest. Actually zone 9 passengers should be boarded second; we are not blocking aisles and can be seated much faster and deboarded faster too.

Was a short flight, not good or bad. Extremely cramped and I'm only 6feet 1inches. 295lbs.

I had a problem checking in as I didn’t have the correct code. I had to phone BudgetAir.com. They charged me an additional 174US for some tax or something in order to provide me with my booking number. I will never use a third party seller again. Absolutely criminal activity. But I did get to where I wanted to go

Was good all around. Crew, food, paid for extra legroom, as 10+ hour flight Like the 787 as I don't have any problem with my ears, due to the planes pressurization.

The flight was delayed for 4 hours and the airplane was really old cuz not one thing was working.

Boarding, offer those who need assistance some time not to be rushed.

They charge 5 dollars for plastic headphones for a flight of 1 hour! Seats are awful. Service is terrible.

The flight was good, the inflight tv's are too old and hard to work

eveythink, because of you I lost 100 euros for my train connection

Excellent experience. Smooth boarding, flying and the staff was courteous.

Nice crew - very small plane and uncomfortable, with no entertainment options…

Could have had available the ability to watch a movie , but there was neither any hardware or place to plug-in.

A snack would have been nice instead of having to buy food.

I flew from Brussels to Munich, then from Munich to Denver. The flight from Brussels was only about 2.5 hours and it was okay. But the flight from Munich was about 12 hours and we sat on the plane for a very long time after everyone boarded. I paid something like $75 for a “preferred” seat in economy and it was so cramped my knees rubbed against the hard shell pocket. You couldn’t turn your legs to the side because the passenger next to you was too close. I was on the aisle but couldn’t put my leg out because there was often traffic or carts. Maybe I’m expecting too much but on such a long flight I’d like to see more comfortable seats. I think it was a United A380 plane. I won’t be flying anywhere that far away again. My legs and feet are still swollen 4 days later.

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

my flight was cancelled. next one scheduled 2 days later. no hotel provided. worst airline experience ever

Crew had connection details for only 2 other flights and gave less than empathetic guidance.

Boarding process was hectic and unorganized. Delayed for hours, THEN delayed for weather.

I had a family emergency and couldn’t board and I contacted underpricer to help me get a refund or just a flight adjustment as i would still be flying later that week, and that hasn’t happened. I will never book a flight through kayak/ underpricer ever again.

Missed our flight to London and we were put on coach seats to Munich.

Seats were terribly uncomfortable! Couldn’t sleep! I paid for good seats when scheduled with Lufthansa, got crappy mid-section seats on Air Canada!

Cancelled flight, that morning! But got us on an Air Canada flight!

No refreshments apart from a bottle of water. No pillows. No entertainment. Flight delayed by 52 minutes.

Great job notifying of 30 minute delay in departure. Fabulous job making up for the time and arriving as scheduled. Air travel is just no fun anymore with the extreme overcrowding, and someone needs to come up with an innovative plan for loading and unloading passengers (load all window seats first, middle seats second, aisle seats last?). Great job getting the luggage on the carousel in record time!

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

Our headphone plug in was broken, especially we are with 5 years old who like to watch a movie

Free food and drink! Got a late start due to mechanical problems w a luggage loader.

App totally screwed me up trying to check in. Would not let me select a reasonable seat and therefore I was stuck in a totally uncomfortable seat for 7 hours. Will not take the chance again and use other airlines in future where no issue choosing seats

Although it was an overnight flight, the crew could’ve have made more refreshment passes.

All and it was good . But no one woke me when meals came around . Please have a don’t not disturb sign if you opted for that . Left very hungry missing all meals .

Not being stuck in the middle seat between strangers but that’s not the airlines fault

On board was excellent—a remarkable positive change. Check in was horrifying. Forced to check in branded cabin baggage approved bags weighing 10 and 12 kgs each, because desk insisted these were not fit for overhead lockers. Got charged £160 for two bags. Behaviour of staff was hostile, motivated and rude. Wonder if BA pays commissions on collection, or borrows staff from Airport operator. Basle evidently is an airport used by budget airline— and customers are treated like consumers.

I was at the airport 10 hour early. I would have loved to drop luggage in advance but this was possible only 3h before the scheduled time, however BA was so kind to move me to the earlier flight as it had space available at no extra cost. Thank you!
