Give yourself enough time to get through customs. You can get many items at the airport but you will pay a bit more.

Getting to Haneda is a nightmare. avoid the Keiku line, rather take the Monorail.

Incheon has always impressed me by its cleanliness so I invariably choose Korean Air over and above others. I appreciate the 2 free checked-in luggage policy. I find the weight limit for carry-ons plus personal item a bit restrictive. I bring a laptop with an AC adapter and that alone brings my carry-on weight close to the limit. Next time, I shall try not to bring other battery chargers (the ones that are not allowed to be checked in).
