This was #1 for me until the NWA double EQMs. I earned 4 free nights that work in any Hilton property! Used my first stay at the Chicago MR seminar. Wll use secon for the advanced MR seminar!

Gone a loooooong time ago. Search for the thread, it's a good one.

For whatever reason, cycling through the rewards cards and the 0% teaser cards has never really had much impact on my credit scores. I expected it to, but it never really moved the actual number much in either direction. I'm usually teasing $10-20k at a given time and working on 2-3 travel rewards cards for sign-up bonus purposes. (Only things I really use are SPG Amex and Marriott Visa.)

In about a year, we will be moving and applying for a larger mortgage. I'll probably clean everything up a few months in advance of that - go in with zero debt and only 2-3 open CC accounts - but I don't expect a magical jump in the credit score.

In addition to what's been said, I nominate:

(1) Double miles on UA Visa and DL Amex tax payments. Never more than 1.25 cents a mile, and sometimes less, if you can pair it with other bonuses.

(2) 25K UA miles for $295 Ameniti membership. That's less than 1.2 cents a mile.

(3) The 35% DL transfer bonus for Amex. I transferred 300,000 points, and got 105,000 bonus miles.

If you have solid & long term credit, then diving into a bunch of new cards really has very little effect.
The "new accounts" category is only ~10% of your credit score, and number of new accounts is only a portion of that.
Also, when doing the rating, the buckets for number of new accounts are 0, 1-4, 5+. As an example, the difference between 0 inquires and 5+ on my credit was less than 20 points. Considering it's a 1000 point scale - that's not so bad.

As with everything else though, buyer beware. Make sure you have the financial footing before jumping on a bunch of credit card offers.

There is a big thread in the HHonors forum here on FT about this. But the key thing is that no one HHonors account will be credited points for more than two participants for any single walk. That means you can register yourself and one other individual as a VIRTUAL WALKER (a selection to be chosen) for the remaining walks and get 5,000 per person (for up to two persons) per walk (as many walks as are remaining). As of yesterday, getting 90,000 points (i.e., registering two virtual walkers per race for 9 races yields 5,000 * 2 * 9 = 90k points).

I agree with GUWonder, Hilton's City of Hope would be the biggest for me.

NW Double EQM would have been great if I could have had a business trip or two during the promo period. I just couldn't work out a MR during the time period.

For those with pretty good credit to begin with, most 'dings' on your credit report for the offers mentioned here are minor. I have taken advantage of several credit card promos in the past year or two for example and have a 'ding' on my credit report for it but I have faithfully closed accounts which were only opened for such offers and my FICO score remains quite high. So unless you have other not-so-creditworthy factors, this should not be a major concern.

It is to your advantage however to not close credit cards which have been open a long time even if you don't use them. But closing accounts with very little history makes little difference.

And note that the FICO scale goes to 850, not 1000 as mentioned above.

UA Ameniti - 25K miles ($295) and I received at least $50 worth of premium coffee and a pair of $150 I-Travel Shoes which are excellent - most comfortable shoes I have ever owned. so that makes it $95 for 25,000 miles - not bad at all.

I am still enjoying the year-long Chase Double Miles Promo [$99] with CO. This one (1) generated tens of thousands of miles.

For me it was the Wachovia and Chase HELOC loans. When you can get over $1 million United points for under $1000 the cost per mile is very low (.1 cents). My credit score did not go down after six loans . The time it took was equivalent to doing six credit cards but a lot more points.

First let me say that ned and Mrs. ned participated in this promotion to the fullest extent possible. Ignoring the charitable aspects of the deal I do not think it is that great because of the price/value relationship. Or maybe I do not get as much value out of my Hilton points as GUWonder.

Ditto to that!

Priority Club 10k bonus points promotions!

My girlfriend and I made good use of the United Round the World promotion out of WAS. We have free tickets (in coach, unfortunately) to SYD next month for doing nothing we wouldn't have done otherwise.
