OP, when is your flights? Maybe (a very very big maybe) you get to choose your new package for 2016 before so the eUpgrade from that get deposit to your account.

You can also try ask nicely at the following thread:

Just not sure if we have that many SE with leftover credits this year with the changes of the Upgrade requirement this year.

if you are indeed willing to pay, call in to move to a higher Flex class that use less eUpg will be the only option.
