Airline reviews

Well, we upgraded and on a 14 hour flight not sure how we would tolerate it otherwise. The upgrades are ridiculously expensive and even with empty seats even in first class it was difficult to upgrade. Probably won’t fly China Air again due to this. The attendants tho were much better than the airlines in the states and there attentiveness and care for your comfort far exceeds other airlines in the states.

Very bad. They don’t allow group people to sit together by blocking most of seats and opening only single seat during online checking in. . By doing so, they can rip off customers at the check-in counter by collecting extra money if we want to sit together in the same row.

Delayed. Not a full flight and whole rows left open with the paid seating. Food was ok. My beef meal only had one cube of beef the rest carrot cubes. Entertainment on personal device but didn’t know about it until the flight was almost done.

I love my Delta crew, they were so welcoming and helpful.

I absolutely loved my flight from Taipei to LAX. I was originally assigned to a different seat, however one of the stewardess noticed I was uncomfortable in my seat. She offered to move me to a more comfortable setting. Although she didn’t have to do what she did, I am more than grateful and thankful for her doing so. My longer flight felt much more comfortable, just by her taking notice. I really appreciate her.

Staff was so nice and very helpful with directions aswell!

Most relaxing long distance flight I have been on. And I have flown on many.

It was our first time flying with China Airlines and had a very nice experience. The airline staff & crews both on the ground and air were very nice. Food on the plane was very good. Will recommend it to family and friends.

I don’t think I’ll be flying them again. Tight seats, no flowing air or air nozzles that you can turn air on you, for those who could have motion sickness this would be your worst nightmare. The pilot was great and experienced (which is what you want when flying 12 hours) overall I’m thankful knowledgeable pilots!

Very routh cabin crew food is only 2 meals for 13 hours fry with them They should get better training how to service good super routh language and talking with customer

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

Headwind delayed our flight which wasn’t the airlines fault

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

After each meal was served I didn't see any flight attendant offer coffee or tea to the passengers after the initial drinks were offered. Other flights I had been one it was standard procedure to offer hot drinks after the meal service.

It was great. It was my first time with Cathay Pacific and I really recommend.

In economy, very cramped. Once the front seat was reclined it was almost impossible to get in and out of our seat. The personnel was excellent.

Selected ovo lacto meal because I’m ok with milk products but not any meat. It was terrible. We had the same selection back in October when we had traveled and it was pretty good at that time. It was gross this time.

I was mid plane and they were already out of the main beef entree....ugh!

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

Vegetarian options should be included with every meal. Even just simple steamed vegetables and whole grains would capture a wide audience.

Cramped, hot and the plane was grubby. Also the plane was an hour late and it took an hour to get my luggage once I got to LAX.

Extensive delays, poor organization to board people, as it felt like chaos to get inside of the plane. No lines, everyone gathering together like a mayhem, very confusing. Passengers out of hand and rude, which is not the airlines fault. However, there should be rules, e.g., not letting one passenger take 2+ spots in the overhead bin.
