The appropriate number of upgrades will be deducted from your electronic upgrade account at the time of travel."

So, do I need to make sure the proper number of stickers is in my account before my upgrade is cleared? Or will the upgrade confirm and then I can buy the extra ones necessary to fulfill it? Don't want to buy unnecessary 500 mile upgrades if I'm not going to be cleared. Never had an issue with having too few in my account. This is the first instance. Thanks and apologies if this has been asked before.
