I am a member of both Delta and Alaska flyer programs, have about 15k miles with each. Nothing with AA or UA. Haven't used anything at all yet but was planning on booking thru the UR portal. Open to ideas if transferring would be better but doesn't seem so considering not having much of anything with Chases's airline partners. Not necessarily looking for 1st class, but would like business, or something of an upgrade from regular economy for the Florida flights. For Hawaii, same thing, even if just 2 of the 4 flights. In my book, I am still ahead even flying economy all around on just points. End goal is to not have to "pay" for airfare on our bigger trips. Whichever program I would benefit from the most would influence which card to sign up for next (80k points on Ink Business or an actual airline card) and which airline for the GSP & NYC trips.
