Drink package upgrade

[whynotme]

Is it possible to upgrade the drink package from Signature to Elite after boarding?  What would the upgrade cost?                                                    Ross

$10+18% ($11.80) per person per day, and both/all adults with the SBP would have to upgrade. See a bartender (not server), and be sure to upgrade before anyone uses the Signature package at all.
