CIF Busan by airfreight

Dear experts/friends ! Some topics in the past related to shipment terms such as CIF/FOB and so on. Now I have a further one as follows:

L/C says in 44F (Port/Discharge/AP destination): Any Sea Port South Korea or any Airport South Korea.

45A shows: ABCDEFG ( = Goods description) CIF BUSAN.

46A requires for Sea shipment full set B/L, if shipment by air AWB is to be presented.

Now bene is requested to ship one package by air urgently and asks me (his banker) now:

1.) If he selects Incheon (which locates at Seoul, as far as I know) as AP/Dest. is the AWB compliant with 45A CIF Busan ? I do not agree, but

2.) how about 44F any Airport South Korea ? Incheon matches this requirement.

What is Your view to this ?

Have a nice further weekend.
