Airline reviews

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.

basic and only minimum of service, they offer nothing special

The staff was marvelous. The entertainment options were terrible, old or 2nd rate movies. I was unable to entertain myself for 18 hours-it made it seem even longer. Note: I thought about upgrading but your information about what was included was unclear. Are the seats bigger? Are there current moves? What kind of food do you get? Would the upgrade compare to Delta? Just saying the upgrade is better didn’t convince me and I regret not flying Delta.

It was a good flight. I would highly recommend it to family and friends.

Plane is new and I was upgraded to first class so all was great.

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.

Overall great experience. All four members of my family were seated together without paying extra to reserve seats. Everything was on time. Food was great and healthy. Media entertainment was good. Rock music could be added as a listening choice. No issue with baggages. Flight attendants were friendly and helpful. I would recommend EVA to friends and family.

As a senior traveller it’s difficult to be seated all the way at the back

I was expecting that movie selection and food would have been better. Everything else was great.

The type of the food requested (Asian vegetarian) was not properly met with. They have very limited snack items that may compensate for the main meals.

Loved that leg room was great for economy, and food was definitely better than other American airlines, great selection of movies. My mom is happy.

Just okay. Staff is accomodating especially at the check in counter and gate. Boarding was just fine. Leg room was cramped at economy. No entertainment, wifi is so-so. Cola in can given by cup, but rest of can was not given. At least give the whole can.

What I noticed is that when customers or passengers are asleep, they are no longer given food.

Flight were late each leg of the trip, seats were narrow and uncomfortable. Food was delayed and poor quality. Overall a bad e perience. I complained and was offered no offset or compensation.

I ask the crew to help me get my bag because I can't reached it she ignore me

ANA’s service was great, and the flight was nice and smooth . They gave us updates and checking in and boarding was smooth and easy .

I have never been a big fan of airplane meals

We purchased premium economy seats 9 months ago and got bumped to economy when we tried to board the plane. It was a huge fiasco while they struggled to find us seats. I tried reaching out to Kayak to see how we can get refunded for the extra money we spent on premium but have heard nothing back. It was a 14 hour flight and were disappointed that we lost our seats after selecting them 9 months ago.

Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

Easy if you are a United States Citizen, when you go to US Border & Customs, bring your Passport if you arrive Internationally. Remember to pick up your check baggage before moving into domestic flights, as they will check the tag for the plane you are boarding in. (They will check your baggage again). Bring your ID/DL (Real-ID COMPLIANT) with you to pass security/TSA, passport works too. SFO is pretty strict as well as LAX. Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

Everything was great, except the Wifi, but that's understandable.

The plane was dirty, there was trash in the seat pocket in front of me.

Food was excellent, the crew was exceptionally friendly, and the seats were comfortable. Bathroom were also kept very clean and odor free.

They woke us up 2.5 hours before the flight was over? Why? If I'm on a long haul flight I want to sleep as much as possible. Also, didn't mention the mattress pads in business class so missed out on using those. The western meal of truffle, salmon pasta was the awful. Had a different fish dish on JAL that was great but that pasta was a mish-mash of too many random things that didn't make sense plus dry fish. Staff was friendly and helpful.

I loved Ryuichi Sakamoto's OPUS in the movie choice.

Too bad the plane didn't work after we taxied out to get in line for take-off. We went back to the gate and waited for almost 90 minutes for them to find a plane that worked. Waited another hour to board. When we got to Rochester we waited for over an hour for our bags to appear. The agent said they only had three people working to load and unload baggage. A one hour flight took an extra four hours. It would have been faster to rent a car at JFK and drive to Rochester.

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

bad… no veg food was provided eventhough i pre ordered special meal

Excellent service provided the flight crew. Food and drinks were very good.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

Not enough food for everyone. . Always run out of food when we ask

I was amazed at how clean Cathay Pacific planes were compared to our US domestic airlines. Everything was great all but the food service I was just okay with. Shorter flights with other airlines usually provided more meals and snacks that I have been on. Almost a 16 hour flight just two meals and no snacks with Cathay Pacific. Even ran out of what I wanted for one of them. Other than that top notch!

My sister and I were booked on flight CX844 from Hong Kong to New York, following a layover from Hangzhou. The scheduled layover was already over 7 hours, and the flight to New York was set to depart at 2:00 AM. At 11:00 PM, I was informed that the flight was delayed until 6:45 AM, significantly extending an already lengthy layover. I spoke with a representative to inquire about rescheduling or hotel accommodation, but she rudely insisted that company policy only offered a $150 food voucher, which was unhelpful as I had already eaten and most places were closing. She refused any alternative support or access to the Cathay Pacific lounge to make my wait more bearable. As a loyal Cathay Pacific customer, flying with the airline every year, I was deeply frustrated not only by the delay but by the poor service and unprofessional attitude I encountered. I believe this situation could have been handled with more care and flexibility.

It would be nice if they could have a choice of both gluten AND dairy free menu. Lots of people have problems with BOTH. I also could not get on their website to check. Phone verification issues etc( not all of us have our phones on roaming. I tried over an hour!

Cathay was not the problem. The problem was the customer service from Kayak/Underprice. Will never book through Kayak again.

The crews were smiling all the time with soft tunes when they spoke; the food was excellent. Thank you!

Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

Cramped seats. Audio jack for the in -flight entertainment was broken.

Flight was great albeit the long line before the int’l immigration given the timing of the year.

They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.
