Evening all
On our corporate booking site my Honors number is recorded on my profile against a chain code of HH, but it never seems to make it onto my bookings so I have to call ahead or sort it out on arrival

.
So I guess it needs to be against a different chain code @:-). Hilton themselves list
a set:
- EH = Every Hilton (i.e., all Hilton Worldwide Brands)
- HH = Hilton Hotels
- HL = Hilton International
- DT = Doubletree
- HX = Hampton Inn and Suites
- ES = Embassy Suites
- HG = Homewood Suites by Hilton
- GI = Hilton Garden Inns
- CN = Conrad Hotels & Resorts
- WA = Waldorf Astoria
All of these appear on the corporate system, plus two other likely looking candidates:
- AW = Hilton Affiliate
- AG = Hilton Affiliates
Which, if any, of these chain codes would get my Honors number through to the property?

I'm guessing EH or HL and could put them both in, but it'd be handy to know which one.
TIA
