I put the review all together for the first review

We travelled with a toddler and was allowed extra time to board first which was very helpful!

Organized boarding process, superb food, lovely crew, even arrived early!

This flight was even more crowded that Singapore to Taipei, an extra row of seats and an additional 4th seat in the middle made it extremely crowded. No leg room, no width for room. Terribly uncomfortable flight. The food was disgusting. We will never fly EVA Air again.

Movie selection was not as good as recent flights I've taken (EVA and other airlines).

Very smooth flight. Superb crew, great food and service. Slept most of the way. Excellent airline.

The boarding was organized and efficient. The crew was very thoughtful and did not wake me up when meals were served. I was totally exhausted after 2 weeks of vacation with a tour group. So sleep was more important to me. The crew just left me a sticker telling me that food had been served and if I woke up hungry to contact the crew. I did have the last meal scheduled on board. Food was very mediocre. The scrambled egg and minced meat were too salty. The porridge was passable. I was disappointed because I have high expectations of food from Taiwan. I thought EVA being a Taiwan based airline would have served its customers better tasting food.

delayed and the cabin crew was like trainees.. a bit careless and not so pleasing to their job

Crew's attitude can be better. I asked one crew member to help to put carry on baggage into overhead bin, but he was not willing to help. I needed help because my height is short. His attitude was bad.

The flight from Taipei to LAX was the first time we encountered rudeness from the crew. From the gate agents to the in flight crew. We had received such wonderful service going to Bali and on our Bali to Taipei flight that it shocked us when the gate agent was rude and then the rudeness continued on the flight to LAX.

Very bad. Flight got delayed and missed my transfer flight twice. Had to stay overnight in Hong Kong and the next flight booked was also delayed.i had the worst experience flying from Singapore to San Francisco. Lots of delays and rerouting.

The flight attendants were very helpful, efficient and courteous in helping everyone!

one hour transit not good. cathay pacific is not helpful at all

First time tying out business class with this airline, hat a disappointment, never returning. We didn’t get the meal as requested from Singapore to HKG flight. While meals served connecting flight, crew takes meal order based off passenger membership status by giving the. Priority selection of meals. It was a battle, plain disappointment, not worth the hype, price, class as categorized/ advertised

The staff were so friendly and accommodating. The food was great. Lots of movies to choose from as well as tv shows. Highly recommend.

Overall pretty good experience. It would be nice to have caught the attendants even they were flying down the aisle with snacks, and if they could cater to multiple dietary restrictions (bland and no lactose. The customer service chat is a bad experience), but otherwise no complaints.

Better. I took an aisle seat this time. Although the overheard compartment above the seat ahead of me kept opening up during flight.

Flight was delayed at the last minute for six hours. Instead of delaying it to a normal hour, they moved it to 10 pm to essentially make it a redeye. There was no compensation or benefit offered for this inconvenience. Once on the plane, Inpaid for WiFi twice with both times it not working because of a “weak WiFi signal”, according to the flight attendants. They also chose the farther possible gates in both airports from the entrance/exit, even though they were one of the few active flights left so late in the evening. Overall it was pretty horrible.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

My seat was sold off to someone else. Had to wait 9 hours to catch the next filght. Definitely will never use Cathay Pacific again. Bad, very bad airline. will comment on google reviews too.

I always fly with Qatar air and you are the best. Keep up the good wor, after travelling with Qatar Air More than 80 times, you never offer to upgrade me.but it happened to my friend companion some time. Any how i still enjoying travelling with Qatar air and wait one day to upgrade me too. Best Regards

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Seat experience average as they use old 777 for must flights despite full load. Qr fares are higher than other airlines for same routes so they should at least upgrade the planes . Food is average and same dishes for months on most routes I travelled at least - the Arabian rice dish “Maqboos” on every flight for months - I am sure there are other food Arabian dishes ?? It’s become boring ! Crew is always good which makes up for these things but hey confirm us what we need

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

From Montreal to Doha , we habe two complaints : 1) They want to charge for Seat Selection, claiming that the Class of ticket bought on Kayak did not cover seat selection. It such a penny pinching rule, I told them, since we paid almost $20,000 our 3 tickets , that rule should never exist. Also I reserved my tickets so many months ahead, I expected they will naturally put the family together or move somebody else to keep our family seating together. I filed a complaint, and NOBODY ANSWERED. 2) In Montreal, Qatar has an arrangement with the National Bank Lounge. It was so overcrowded and the Lounge is so bad in terms of service and food, amenities etc... The WORST lounge . Why Qatar not have another arrangement their Business Class clients in Montreal. The Air France KLM Lounger is better, the Air Canada Lounge is better. Qatar should send somebody to take a look ! Joseph Chung

Was required to print a boarding pass, which I'd prefer to avoid. Seat (economy x) was comfortable, service was excellent.

Luggage handling was very very bad. Damaged my new Calvin Klein bag and delayed another. Still did not get it since 2 days. Worst airlines and service.

Flight delayed by an hoir or more. Food service is slow. Also, the crew is not following up on orders. Travelled in business class and was a platinum member, but still didn't receive the expected service .

Very good in business class but not so good in economy.

Horrible, by all accounts. Delays, lack of communication, just horrible.

The flight was delayed which cost me to missed my connection flight.

My gag was left at liayad airport when I landed at jeddah airport 9 am I waited for my bags at jeddah airport till 2.45 pm almost 6 hrs bad very bad

Apart from chaotic boarding - which I totally understand was outside the control of gate staff. It was comfortable mid haul flight. Well done to cabin crew for their patience and hospitality with largely elderly passengers returning from pilgrimage.

Overall a great experience, no movies were available. Bags were delivered a bit late. Seat controls were not working well. I couldn't make my bed fully flat.

It’s very tiring journey with only 3 seats in a row and not good for family of four. Online checkin don’t work and unable to select the seats while going.

Make the food options available, than running out even before mid way through the service.

Plane is very old and not the same seating as online No per seat entertainment The large shared tv wasn’t working Didn’t provide headphones No announcements of departures or arrival from captain or crew

The plane was bad, a lot of pressure in the cabin, I was in pain and my ear drums almost popped

I cancelled my flight in March and have been waiting for 3 months for the refund. Both flights have taken off and returned now and still no refund.

great flights both ways on time both ways.staff(ladies) where great at check-in.

Food was great, I wished there was better options for movies.

737-8 Max is an awful design. Toilets in the rear are inaccessible for most of the flight due to service carts.

Flight was first delayed for 1 hour, then was cancelled. Communication was poor. I ended up booking a new flight on a different carrier to return home. I heard people in my gate area on the phone with Air Canada customer service who had to inform them that the flight was cancelled and they weren't being helped because the system hadn't caught up with what was actually happening.

Other airlines offer free wifi to business class customers, Air Canada does not

Every flight was canceled and they didn’t care much about their passengers

Crew attitude and attentiveness. Comfort of the seats. Entertainment options.

this flight was exceptional due to the plane itself being updated with longer seat belts so no need for the extender and access to a tv.

Flight was delayed for over an hour making our connecting flight impossible to make. No notification that we had been bumped to another flight. Was told my bag would stay at the airport. Got to my hotel and got notified I needed to pick it up. Come all the way back to the airport to find I didn’t need to pick it up and the app glitched. They did at least put me on the next available flight. No offer for money back or compensation for time lost due to being home a day later. No compensation for food as it was only good for anything in the airport. Not outside it. They did at least book the hotel and the gate agent was very helpful. But I did not appreciate them giving my seats away to stand by people while I was sprinting through the airport to try and make it to a flight I was late for through no fault of my own. If they did not let stand by on I would have been on my flight as they did allow two people before me on
