Thank you. Unfortunately HND does not seem to have express security unless in F or top tier elite (even business class can't use them!), so we will rush off the plane and try to get through as soon as possible. Arrive at 8:15 -> off the plane and to International Terminal by 8:40 -> get through security and in the lounge by 9:00 -> board at 9:40-45 I guess. If everything lines up perfectly.

Something tells me I should have stayed overnight at Haneda instead of Itami...oh well
