For me, CO has been posting flight activity within 72 hours, often with 48. (Not counting weekends).
For Cars, National and Avis were within 1 month. Don't get me started on Dollar. I've waited on average 3 months, and have had to call once or twice. I'm looking elsewhere.
For Hotels, Radisson has been very quick (within 1 month). Ditto for Starpoints.
Hilton, I'm ready to write them off completely. Life is too short. The hotels I've stayed at makes a Motel 6 look like the Ritz and I'm tired of playing, "Will they or won't they" with mile eligibility.
MCI - every 9th and 22nd (or thereabouts), I've been getting my 5K.
Chase Card - faithfully every month.
CO bonus miles - within 1 month usually.
Travelocity promotion certificates - slower than death, but at least they arrive eventually.
