ICN-ZRH with 2-3-2 business 777-300ER
 

Looking at ICN-ZRH and the seatmap shows 2-3-2 business class on 777-300ER. Do I understand it correctly that it's a regular lie flat seat similar to A380 and not Apex suite?

Another option would be AF new config with direct isle access, but it requires extra connection.

Correct. If the website links you to that config, that's the one currently planned to fly.

However, last summer season for ZRH they had some days using the 777-300ER with the old business and some days (most of them) with the new Apex suites. So this can easily change with time or according to days/weeks.

Thanks. Do you think AF with guaranteed isle access + connection is a better option vs KE maybe old / maybe new seats nonstop?

I'd say that a direct (nonstop) flight is a luxury in itself. But that's just me :)

It depends if you value the new product (AF), or the overall comfort and ease of a nonstop flight.

I think any business class with 2-3-2 seating is horrid. I'd seriously go out of my way to avoid it, but I'm spoiled by aircraft with 100% direct aisle access in premium cabins.
