I just tried this entire list for an upcoming reservation in Raleigh, NC for next week. The best rate I could get using my corporate code is $89/day. However, using the first code on your list (A074800), I was able to get $60/day. Any idea if ID will be required for this code? Can you offer more details on this code? I believe Citicorp is a bank. Why would they offer a car rental code? Or is it for employees/

Non of the "international" codes seem to work in the UK...

True but K444404 gives great rates incl. unlimited mileage and CDW insurance in Germany

Some of the AWD's that I did not test may still work for international rentals (i.e., UK). But anyway, try U606753 for a UK rental (this code is for Anniversaries Membership Scheme [AMS] of the UNIVERSITY OF MANCHESTER). Or try Google with the following keywords:
conference avis awd month year location
where you replace month, year, and location with your required data ...

Good Luck!

I have yet to show an ID for any of the codes (unless it says "DO NOT USE ...") If someone would ask, simply mention that you have been a LOYAL customer of Citibank and that they send you this code by mail for leisure travel! I'm in the computer business, so I use mostly the IEEE code (no, I'm not even a member) but not once did I have to show an ID or membership card!

Also, try Google with the following keywords:
conference avis awd month year location
where you replace month, year, and location with your required data ...

Good Luck!

Here are a few new AWD's that provided me with great rates for Seattle (but may also work elsewhere!):

D004951 - 6th Annual Symposium on Advances in Breast MRI Wynn, Las Vegas, Nevada October 11-13, 2007

J659136 - AAS (Historical Astronomy Division) and the AAS (High Energy Astrophysics Division)

J818577 - OJJDP�s Internet Crimes Against Children Task Force Agencies

T788599 - 23rd International Trauma Conference held in San Antonio, TX


Good Luck & Good Travel!

WARNING: DO NOT use Avis C03___9 AWD discount code anymore. I got a
very reliable confirmation from an inside guy that this code is black
listed now. Effective immedately, all benfits associated with code are
removed(including free LDW insurance), anyone use this code will pay
maxiumum rack rate regardless of reservation or website showing rate as
well as company ID must be produced. A warning flag has been raised on
this AWD and most likely you will be questioned about where you got the
code. All in all, this code is nothing but trouble from now on.

Oh well, it was great while it lasted.

Well aren't you clever! That sequence brought up a whole bunch of new discount codes, none of which improved my rate, but it's a neat trick. Will have to remember that in the future.

Thanks for the advice.

$44.82 over the standard rate and $24 saved versus the AAA rate. Thanks a bunch.

I just tried ALL of my AVIS AWD's (except the recently black-listed 'C031529' [Thanks Acrossenger for the Warning!] and the DO NOT USE ones) and the best rate for a mid-size 3-day rental in Seattle , WA was about $137 (incl. fees & taxes). So I gave Priceline a try and I was able to shave off almost 50% !!!

Thanks, yes that one works, but discount not great, maybe 10%.
I will stick to my PC AWD for now

If you give me the exact dates/times of travel, pick-up location, size of car, and best price you found, I'll see if I can find something better

Nothing seems to work for St Thomas, USVI. Any ideas?

What the heck is "Delta PAL Program Employees". Does it relate to the airline, the dental insurance company, the Canadian hotel chain, etc. ?
