Airline reviews

We boarded late and it snowballed from there. Had to wait behind 6 other flights to take off before us. Then, arriving late to our destination, we had to circle in the air for 20 minutes. If that's not enough, the seats are very cramped on their iteration if the A321neo. I'm 6"3' tall and my knees were pressed against the seat in front of me. These are not the slimline seats that offer less cushion with more leg room. I had no room to move my legs. Since I am an adult male, I also had no shoulder room. I sat on an aisle seat to have some space to lean my should out. But the walkway seemed to be more narrow than I am used to see. I felt bad for the middle passenger because there was just no where for me to put my shoulders except into the middle seat person. I don't plan to fly in this airline again in this configuration. Pack everyone in and lose my business.

We really enjoyed our flight to Seattle. The food was great and service was attentive.

The crew are amazing. Very professional, polite, kind, and accommodating.

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.

Flight attendants. Food, entertainment and most of all, be on time.

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.

The flat bed full lying position is not comfortable at all, this could be improved, it is at an awkward position which i dont have the same issues with other airlines business class.

The flight was uneventful and the crew was kind and professional. Really appreciate the option to order a vegan meal for the flight!

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