Another of my favorite is Visit TOHOKU Fare by JAL. Although I am self-claimed train geek, cannot beat 5400 yen per segment!

Add little more miles into AAdvantage account by flying JAL. Buying Class-J seat for 1000 yen and bonus miles into my AAdvantage account. As OneWorld Sapphire boarding JAL flight, the gate machine will make different “Bing” and a gate agent will walk over and bow to me thanking for being a royal customer. Got the impression that flight attendants on JAL go through passenger manifest and try to remember seat number of elite frequent flyers. I being asked how I liked new JAL Sky Time flavor compare with previous flavors.
