Some clarifications:

I stand corrected on the AA/BA award. I checked my old notes again and business class was 150K.

Regarding the UA award, their web-site still lists (or did a couple of weeks agao) a Business Class ticket for 90K to Asia (though it will not book it to DEL). When I called UA they said that it was 90K; normally it should be a little bit more than the regular Asia award. I could not book it since my (wife's) travel has to be on specific dates in March and the RTW starts on April 1.

In any case, 150K on AAdvantage is still much worse than 100 (110K) on UA, though these programs are very similar in terms of the ability to earn miles (maybe UA is better).
