LLRIND fares
This is definitely OT but I'm going to post it here because it doesn't really fit the MR forum...
Have you noticed the LLRIND DEL fares? The base fare is $848+ from ORD (other origins available for a small premium), and doesn't need to be on the AA non-stops; AF/LH/BA etc are valid carriers on the Europe-DEL segment. AY is also available on the non-stop HEL-DEL, and AY offers full AA mileage credit on their discounted fares.
But the real deal is that you can add stopovers for around $50 each. Which offers some crazy possibilities, ORD-BUD(o)-DEL(o)-ARN(o)-ORD, for example, is $898+. DFW-MAD(o)-DEL(o)-MOW(o)-DFW is $1003. (Yep, Moscow in May is nice!)
There is no minimum stay requirement in DEL; immediate turn-arounds are possible.
This fare appears to be a great way to get a nice multi-stopover European trip for this fall or late spring - and rack up a bunch of miles.
