HND/GMP vs. NRT/ICN
If I may piggyback on this thread:
I am planning a short trip to Seoul. I can see the obvious upside to using HND(Haneda)-GMP(Gimpo) to NRT(Narita)-ICN(Inchon). Both HND and GMP are somewhat closer (are therefore more convenient) to their respective city centers. On the other hand, NRT and ICN have the NW/SkyTeam lounges that I use. Any other points of relevance that I may have overlooked as to which of these airport pairs are preferable?
On a side note, KE(Korean) and OZ(Asiana) both fly these routes and have comparable fares. Setting aside for now any elite status, which would you fly?
