Ya can look the agreement up on line...I gotta go fly. HND was the Tokyo airport when the 1947 agreement was signed,,,so yes it applies to ANY Japanese airport. Northwest, Pan Am and Flying Tigers were allowed to pick up Originating Pax/Cargo and fly them to foreign destinations.....

And yes apparently it is 4 T/O slots to be divided among all US carriers. Another reason not to buy off on this silly JV. 4 slots does not change the competitive picture of Japan. Let's not give up our 5th freedom rights for a new bilateral.
