I use the lion's share of my non-LUV FF miles for saver coach R/T's to HI, and since for years DL's HI award was only 30K miles as opposed to 35K for everyone else most of my business and partner point to mile conversions went to DL.
With DL's announcement that starting in Mar 2004 coach HI awards will be 35K miles I no longer have any reason to intentionally steer my business to Delta.
I'm burning my DL miles before Mar 2004.
