Here's another example, of many, of the broken DL award ticket engine.
On Delta.com an award ticket SAN-AMS-SAN for July 2010 priced at 245,000 miles for business class. On NWA, the EXACT SAME FLIGHTS AND DAYS, priced to 100,000 miles.
So as a PM DL is charging me 2.4x the price for an award ticket vs. NWA.
Another example: SYD-LAX on Jan 26,2010. The NWA coded flight is 120K miles for business, but 185K for the DL coded flight, but it's the exact same airplane. So Delta wants 50% MORE miles for the SAME flight?!?
