Checkin was easy and quick. Crew everywhere was mostly courteous. A ground crew in incheon even called my hotel to request my shuttle from his own cell phone! Excellent service, and they were all gracious and helpful till then end! There was some difficulty in coming communicating in English but still I feel we were treated well. Thank you Asiana!

One thing I didn't like. My dad needed handicap assistance but he can walk, so we lined up to the side of the terminal where priority boarding will take place. As I saw crew members assisting and lining up wheelchaired passengers and approached one guy to tell him my dad needed wheelchair assistance, he dismissively looked at me and my dad and told me 'well if you want to sit on a wheelchair go sit on a wheelchair, and walked away assisting other passengers. that was so unhelpful! They were also very strict about weight AND size of carry on luggage, but inconsistently so though. With 2 kids and a handicapped dad, one of my cartons with a 'approved' tag was flagged at the gate and required to be checked in. As I didn't want any more hassle, I said yes so my daughter and I ended up with nonovernight clothes for our incheon stay.

Old, uncomfortable seats. No in-seat power. Weak entertainment options on tiny screens. 3-4-3 configuration means no seat is a good seat. No legroom. App sucks--good luck purchasing choice seats on it. Not enough beverage services; I was parched and desperate for water throughout. I hated my experience on this airline and will work to avoid on future trips to Asia.

The business class seat is cramped for business class standards. I also wanted seconds for dessert but somehow I was made to feel it was not allowed, that the FA has to check with someone if there was enough on board. Mind you the plane was not full.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
