Just a reminder, as you will have to go landside after rechecking your bags and leaving the Customs Hall, should you have bought any Duty Free alcohol or other larger bottled liquids at FRA on onboard your flight, you'll have to pack these items into your checked bags since you won't be able to take them through Domestic Security.
So if you plan to purchase any such Duty Free, put a Stick'it Note into your passport right now with this reminder so you don't forget in the chaos of navigating through immigration, customs and YVR itself.
