Well, perhaps, but 1) isn't it measurably less costly for you to get to and from MRU at the start and end of your trip than NRT? And, 2) with the cost savings of ex-MRU AONE4 versus ex-NRT AONE3, wouldn't the price difference pay for a good amount of your land costs for the trip? Also, if using ex-MRU, you can stop in London on the way back and not go continue on to MRU at all until you're ready to start your next AONEx trip (within one year, of course). Just my 2¢.
