Ford not that great the seat not to big for leg room like other airline

It was ok. Not good and not a bad experience

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

Not accommodating ground staff On board slow service Crew members not very friendly

lunch was good; breakfast was kinda meh cabin temprature was way too high new entertainment system but somewhat limited content

My flight was diverted to Atlanta and I was not given enough time. I paid my travel on April 23, 2023. It was originally Delta from Norfolk to NY, then Korean Air from NY all the way Philippines which is my final stop. Instead from Atlanta to Korea I flew Delta which is okay. Then Korea to Philippines, I flew Asiana Airlines. What I did not like, Ieagle did not sent me an email that my flight was change and so when I went to check in Wednesday the 10th, at 4:30 a.m they told me my flight was delayed at 6;00 p.m and diverted in Atlanta and I am flying Asiana from Korea to Philippines. I do not appreciate that Kayak or Ieagle chenge our flights 5 times and then last minute change again during my day of flight. I hope that you will not make any changes of my flight o Feb 15th because it has to be the same flight with my husband. That is the reason why we made the arrangements early on.

Wonderful cabin crew!!!!! Food was poor, in flight entertainment was just ok. They need to serve more water on a 15 hour flight--we were dehydrated and kept asking for water.

Going through security a second time to get on the next Korean Air flight was utterly ridiculous and unnecessary. We were in a International secure area.

Food was good, but it can be better if it add a little bit of oriental flavour, service is great too.
