This just shows you how much better the travel packages are than the ala carte points for miles redemptions. I'm assuming for account 1 you are doing a travel package. That will also get you SWA's companion pass. With only 90K left you're well short of another travel package and those ala carte redemptions are an awful value. If you have any Chase ultimate rewards points it maybe worthwhile to go that route and transfer directly to SWA for account 2.
