July Inside Flyer has a piece on DINING DILEMNAS DIAGNOSED, regarding the above.
My recent experience with NWA/DELTA only is:
Since 1/99 both have changed to the Dining ala Card program.
http://dalc.com
Used NWA for visits 1/99, 2/99, 3/99 & 4/99 & all visits were posted correctly by the end of the next month.
Used DELTA for visits 5/99 & 6/99 and all visits were correctly posted. In fact, visits on 6/30/99 were posted to Delta acct on 7/13/99. I expect 7/99 visits will be posted by 8/99.
The only problems are:
1-The 800# call in service is a little slow to respond.
2-Both the NWA & DELTA promo stuff promises at least 3 written directories/year if you use the program. I've used the program & have called about the directories & have never received any. HOWEVER, you don't need the directory since the listings @dalc noted above have been 100% accurate.
In summary I like the NWA & DELTA programs. Why all the kvetching?
