I tried to find a more correct forum to post this in, but I guess this is the right one. Sorry, if not.
I have over 350K miles scattered over various airlines and would like to consolidate, convert, transfer or use some of the smaller balance accounts. Hotel points, I typically use for free rooms, weekend get-aways etc. as I earn them. I mainly concentrate on HHonors and Priority Club, but I would like to possibly convert or consolidate some of the other chains into either miles or points (HHonors/Priority Club) too.
Any suggestions ??

ps. If it's not on the list, well, then you are out of luck!

Moving forward, you really need to learn and understand about alliances. It makes no sense that you have tiny balances in airline programs that are partners with other airlines where you have large balances and/or status. It is 100% impossible to move these miles after the fact, but it doesn't make any sense to keep up the insanity.

Spanair, United, and US Airways are all in Star Alliance. Unless you have very unusual travel patterns, it never makes sense to actively belong to more than one program within an alliance. Since you are primarily in US Airways as your *A program, when you flew UA or JK (Spanair) you should have given them your US Dividend Miles number rather than joining their program.

Likewise Delta and Northwest have been partners for several years (ignoring the upcoming merger, they're both in Skyteam already). You should have given Delta your Northwest number instead of your Delta number. Also Korean Air is Skyteam and should have gone into your primary Skyteam account, NW.

Alaska (AS) is like Switzerland - it's not in any alliances but it is friendly with all its neighbors You could have credited your Alaska flights to your Northwest account (or Delta, but we've established that NW is your main program in Skyteam.). However, you also could have credited instead your AS flights to American, as they also cooperate. Or you could have credited your AA flights to AK.

There are quite a few FTers who don't use an AA, NW, or DL account and instead credit all those flights to Alaska due to its wide range of US and international partners which cross alliances.

At this point, once you figure out which programs to earn in going forward, there's not much you can do with the small balances other than get magazine subscriptions or maybe some $25 dining card or gift cert depending on the program. I'd suggest you keep using the NW program for all your NW and other Skyteam airline earnings, along with any other future flights on AK. Don't worry about the orphaned 10,400 in DL because within a year or less after the merger, the NW+DL accounts would be combined. I would make sure you buy something through the DL mall or do some small activity to make sure those DL miles don't expire.

You could keep the AA account for the apparently rare times you fly AA or other oneworld alliance carriers. Maybe even credit any future Alaska flights to it to help top it up to a reward level, instead of crediting those AK flights to NW. Or dump that account and do the reverse, crediting AA and other happen-to-be-oneworld flights to AK instead, building that up. But you really don't have enough miles in either of those programs to care about.

Hotels - given you have low bals in all but HHonors, I'd change your earnings preference at the other Points-OR-Miles chains to earn airline miles instead of points. For example Choice Hotels gives 250 miles for each stay; I find that more valuable to feed my NW or UA programs per-stay than saving up Choice points, since they're maybe my 5th choice hotel program. Otherwise don't think you can do much useful with those other low balances. As far as Hilton HHonors, I don't know if you're earning Points-and-miles or Point-and-Points. If you value the miles more, you probably want HHonors set up to feed your primary airline program (which looks like it should be NW). If you are saving up for Hilton stays, then probably Points-and-Points is a better deal going forward, at least until you hit your target HH award level.

I would go even farther than the last poster. Try real hard to stick with one alliance. I have a slightly different strategy. UA is my main FF program, but I credit any flights < 500 mi (since the UA 500 mi minimum went away) to BD (BMI, who is also a *A partner) since BD still awards a minimum of 600 mi per segment. I also credit Hilton Honors to BD for miles and points since Hilton gives BD a minimum of 1000 mi. I credit Hertz to BD as well since you can get 1700 mi (and even 3400 mi with a current promo) per rental. I don't really lose anything doing this because those Northeast 160 mi flights on United Express are all Saabs, CRJs, etc., where an upgrade is not an option, so I might as well collect 600 mi per segment. BD miles are quite useful because they are *A, but without the star net filtering on awards that UA does. BD also has one way awards and awards that combine miles and $ to give you more flexibility. I try hard not to stay at hotels out of my main alliance or fly airlines out of my main alliance. It isn't always possible, but I try to minimize it. One tactic a lot of people have is to collect in two programs for those times when you can't stick with your main one so that you have a fallback position, i.e. maybe stay at Hilton and Hyatt or Hilton and Marriott, etc. I used to do what you appear to be doing such as flying the cheapest flight or the quickest, most direct route and ended up with orphan miles in many different accounts that did me no good. Sure it's a pain sometimes because you need to connect when you would rather not, but at the end of the year, you will be better off for doing it. As a UA 1K, I haven't missed an upgrade this year, even on difficult routes. That wasn't the case when I was both a UA 1P and an AA Platinum. You will see similar results with your hotel programs. It is better to be a top tier in one hotel program, then it is to be lower tier in 5 programs. Good Luck.

You are a 1K, so that means that in the same year you hit 100K EQM with UA and direct the excess *A miles to BD (BMI)? How many air miles over and above the 100K or so (maybe some non-BIS EQM in the 1K mix) do you accrue? If it's another 50K, then you are forgoing the extra two SWUs that come at 150K and whatever token is there at 125K as an elite reward. (No big deal, since 2 SWUs and that token are minimum incentive to do an extra 50K of flying UA, IMO.)

You cited various examples of benefits to having BD miles as opposed to UA ones, but didn't mention the possibility of lounge access in US if you are BD gold. (Would you explain "without the star net filtering on awards that UA does." Are you referring to the difficulty of getting *A awards on other carriers using UA miles?)

So love the idea, but all my efforts, at least the flying ones, are needed to hit 1K.

I may hit 125K BIS on UA, but not 150K BIS. I don't really need 2 more SWUs. I think the key thing is that the flights I am crediting to BD are the <500 mi segments. Suppose I fly PHL-IAD. That's like 60 mi. Even at 100% match as a 1K, I earned a whopping 60 mi EQM and 120 mi RDM. The 60 EQM aren't really going to help me, and I am not making 1K on segments, so it makes more sense to me to credit those to BD and get 600 mi minimum per segment. I am already an RCC member, so the lounge access isn't really a factor although others certainly take advantage of it. As far as star net filtering goes, there are plenty of threads about it on the UA forum, just search for it, but basically what happens is that UA, unlike most or even all of the other *A carriers further filters flights available to the *A members. A great example is that it seems like once UA hits a certain number of LH awards, they just stop making LH awards available until perhaps the end of the month, the end of the quarter or some other unknown condition. So you can see a flight is generally available to *A for award using the ANA award tool, but UA says they either don't see it or it isn't available when you call in to try and book it (this is because start net filters it). BD doesn't do this, however, so you have another option for booking an award that may not be available to you at that moment using UA miles. For me, it's all about having options relatively painlessly.

MarkXS - your analogy for Alaska is quite good!
All: When evaluating for a Mileage Makeover, is it not important to find out early on the OP's desire for "point miles" (spendable points) vs "status miles" (accrues status benefits)?
In the OP's example, if the 185k NW balance is spendable points earned on a credit card, and the 124k balance is seat miles on US, the recommendations might be quite different. OP needs to add more details.
Another imporant point mentioned already is How Fast does the OP need to move, especially on the larger balance items?
OP: Make a chart and design an Action Plan with deadline dates, or you risk losing your balances all together.

Thanks for all of the excellent advice.

I did not realize that I could give Delta my NWA number, etc. - I almost always make my reservations on-line through the airline web-site and never saw any option to input partner numbers.

I do fly both USAir and NWA, but the majority of my NWA miles have been earned through bonus programs and credit purchases. The USAir miles are 90% seat miles.

KoreanAir has been 100% earned with credit card purchases - I'll make a switch there after I earn a redeemable amount of miles. Some of the real small balance accounts reflect sign-up/registration bonus miles.

AA and Delta were flights booked for me by others; but had I know that I could use the partner account, I certainly would have.

Interesting to hear that you are earning miles on KoreanAir with a credit card. Is that a $USD Visa or MC? I assumed, perhaps incorrectly, that foreign (non-US) carriers did not have $USD cards, after reading that one had to live in Japan to have an NH card.

Yes, it's a $USD Visa card through U.S. Bank.

There is no option on the DL website to enter a partner number. Until the SkyMiles/WorldPerks merger, months after the actual DL/NW merger, if you prefer NW miles, then be sure not to login to delta.com when buying DL flights. You can add your NW # at check-in, or via online web-chat at delta.com, or if you're really lucky via the DL phones - but it's practically impossible to get DL to get the DL number OUT of the reservation after delta.com automatically enters it if you purchase while logged-in.

Hopefully that gets better after the merger (for other partners) because I believe that Delta has already announced that the nwa.com website infrastructure will be the basis of the new delta.com post-merger. But in the meantime, don't log in!

Perhaps I have been extremely rare case, but in the past having purchased flights via delta.com under my DL #, I've called and the rep (first and only one I've had to talk to!) changed my # to my NW # without any questions or hassle.

I think I'm a lucky one.
