I've never had the mileage post automatically with the carrier I booked but was unable to fly HOWEVER I've always been able to get the credit through a quick call (or email). I wish this would happen more often, DOUBLE BASE MILES!!!
and, BOTH airlines are partners with SINGAPORE AIRLINES, so if you set up a KRISFLYER account, you could even mail COPIES of the tickets and boarding cards with a form they have, and put 3 US Stamps on it, wait about 2 months and you would receive credit on THEM as well!
hehehehe.
even without the rerout thing, I probably did this particular double dip about 15-20 times in the course of 5 years. I finally stopped because, well, I was flying both DL and UA a lot less and I felt bad. As well, Singapore deletes blocks of miles regardless of continued activity--it's all based on when you earned them vs how fast you redeem. I ended up losing--no wait--not getting to doubly use about maybe 7k miles on them. Not bad.
I probably should not have posted this because it probably still works. Oh well. Call me the pudding guy.
