Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

Humm, I should have known that the seat I peaked on my flight from Inchon to Manila was designed for a toddler or very small person.

The staff hold my luggage to steel and exchange my stub, i was very disappointed.

Kayak uses scammer sites to steal money from their victims.

Kayak along with airfare assay are attempting to steal my money. Charges are being pressed.

Customer service and attention to details. The food was good.

Felt like the oldest plane in Asiana Fleet. Screen was 5-6in only and no charging at all. Movie selection wasn't great.

When one asks for water because they are dehydrated, bring more then a sip or two in a small cup. Bring them a whole bottle.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

I am thankful that I was able to fly using Asiana

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

WiFi didn’t work on two of four planes. Flight attendants were not overly friendly or welcoming. Planes were extremely slow to board and deplane.

Delta does a great job with entertainment and free wifi. I can still be in touch with my colleagues while in the air.

Aside from a completely packed plane, I really have no complaints.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

It was a pleasant surprise to have complimentary Wi-Fi on the flight

Much better than Latam, the worse airline company ever. I hope I don't have the need to fly Latam ever in my life again.

Seats in Delta Main are unbelievably close to the seat in front of. Hard to get a backpack under the seat.

The flight was operated by Latam. The aircraft had a technical issue and the flight was delayed for the next day. They grounded other passengers to get their airplane assigned to my flight. Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

It's a short hop. My carryon was checked at the gate, I didn't have to drag it all over the airport. Excellent wheelchair assist.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Friendliest Flight Attendant I’ve seen since I flew on Southwest Airlines. The whole trip was outstanding…and arrived Early!

It was good overall except from Omaha to Denver when flight a was a repeatedly delayed apparently due to some issue at Denver. Communications could have been handled better. I had to board then deboard with luggage and board again

I didn’t have a seat assignment and my seat was very dirty on the flight from Frankfurt to Budapest.

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

No screens or meal options. Freezing cold. Dirty seats. Left late.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)
