Wow, thanks, so much info. From what I read everything seems to work the same for first as economy... just need more points!

Since this is supposed to be "nice" trip, and it's only for one way, figured it might be a good time to be comfortable on a longer flight. That's always the worst part of the end of vaca, that flight back brings you back to reality real quick. Hubby's never had a taste of first so since it's points, might as well splurge if we can and extend that vaca feeling a bit.
Seems like AS is distance based too, which is why it needs 30k at least for ANC to PHL. And that's the lowest for first, as a non refundable. It's goes up to like 60-70k one way

If that's my only options we're moving to the back of the plane, hehe.
Ah, sorry about the transfer partner confusion. I have MR, SPG, and UR points in the budget to use for this, but no direct airline points. We don't fly much outside of SW for personal. The points I had been earning from business trips I managed to let expire on AA (which I still kick myself for, IIRC I had about 12k go poof after diligently keeping them active for several years), I still have a couple thousand in BA Avios and the same in United. But no where close to actually being able to redeem them for anything

I think hubby has nothing because I forgot to try to save the little bit he had in AA and before that I'm not even sure he opened a FF account from his UK trips for work (he does kill me sometimes) but if he did those were forgotten and expired too. So I think I have points that can transfer to either airline, either directly or roundabout. And I'm not married to AS or AA but they were easy to start with.
We only need a one way for the flight. We're doing a one-way cruise to Alaska so I'm looking for the flight home, which is why we can splurge a bit for First if I can find the right award. As a random date I picked 5/3/2019 - it's also shoulder season like we'll be in for our cruise in Sep 2019 - just to get a feel for how many routes are available (and comparing to the routes available in 9/18) and rough ideas for points. On that date AS has an option for AS106 > AA2113 for 25k in first. However, I just figured out why, I think. It's first AS but Coach AA. When I looked it up before I happened to be on the mobile site and it doesn't show the class in the flight details there that I can see. That seems like a kinda important detail there. Silly me for assuming they'd list that when booking a non-refundable flight.

So that probably explains why it wasn't an option when I searched on AA for First Class awards. I guess if I want a cheap First seat I'll have to put up with a few stops

(note to self, pick out a route that has PP lounges for the layovers, hehe)
Torn on picking up more cards for the flight. I know AA should be easy but I've had a ban on Citi since I closed last card with them years ago out of aggravation (and reading all the "citi being citi" posts on reddit just tells me they're still the same or gotten worse since I had them) and honestly, Barclay's scares me a bit

BoA is kind of tolerable but I'd have to be for sure I want to fly Alaska for that. Current plan for the budget is 50k UR and / or 50k MR for this flight. Hoping for "or" because I'm cheap but that's the only thing these points are budgeted for so if I need to use both I'm ok with it. Also have a pile of SPG that I can use if needed, if the MR isn't enough and I can't use the UR to augment. Seems like I'm up for more research still
