We got to move to the front of economy which gave us more legroom which we needed.

They changed planes on us and we lost our upgraded “premium economy” seats.

I was given the chicken dinner when I asked for the beef one - did not realize until the flight attendant was far away so I couldn't switch. This was a 13 hr flight - attendants did not offer water during the flight. No video options in English, only 1 channel on the screen on my seat, movie played on screen in front for all passengers to watch.

I liked the service from the cabin crew

I hate that I couldn’t use my phone on airplane mode. What’s up with that? I’m not a fan of Airbus. Boeing aircraft are superior

The service is great. The food good. The seats are standard sleeper seats, so also good.

the wine selection was not so good. They could do much better with the wine. It’s not the cost it’s the selection. For the same price range they could have better tasting wine.

Bags were not checked through to Cebu because of the 10+ hr layover. Had to go out to arrival area to follow up on bag transfer. Korean Air wouldnt issue my boarding pass for my INC to CEB flight at LAX so I have to get in line again at the Korean Air check- in counter in INC then was told to go to Jin Air since it was operated by them. Jin Air wouldn't issue a boarding pass because my flight was at 8 AM the following day. I ended up sleeping at the predept area until the counter opened.

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.
