My experience has been that DL miles (if in the eligible flight number range) post just as quickly as AS/QX flights.

The elgible flight number range, though, is horribly out of date, and has been since Delta started the Northwest integration process back in October.

Now that all NW flight numbers have been converted to DL flight numbers (which occurred about 2/1/10), would it be too much to ask that the eligible flight number range for DL flights be updated on the AS website?

A mainline DL flight from MCO to MSP is outside the range (DL 2437) and requires a manual miles request. The old NW flight number (also 2437) was a qualifying flight number.

It might be that DL will continue to tinker with the flight numbers --- but it sure could save AS a bunch of time on manual entries for DL if they'd only update the eligible flight number range to reflect the current DL reality.
