All of the UA/NW bickering is really laughable - the companies are employing vastly different TPAC strategies, BOTH of which are (or have the potential to be) successful. There is money to be made both in maintaining a strong NRT hub AND in offering NRT-bypass flights. The more important thing, IMHO, is for both carriers to continue improving their premium cabins in order to effectively compete against the likes of JL, NH, SQ, and CX.
