I only answered your question directly without offering any other options.

Please refer above to the suggestion by [MENTION=742310]24left[/MENTION]

But since your husband has 30 and you have 20 and you both each need 21, I'm not sure if applying your booking as his nominee takes partial credits... IIRC, it takes the full count of eUpgrade credits meaning it would remove 21 from your husband's account instead of 20 from yours and then 1 from your husband's... The last time a nominee used my eUpgrade credits was many years ago so someone else might have more up to date info if this has changed or I misremembered.
