can you upgrade with miles if you buy a ticket with cash?
also how close to departure you can upgrade?
You can upgrade cash tickets as long as the fare class is eligible for an upgrade(to premium or business). You can check eligibility of an upgrade during checkout process on ANA website; you can request upgrade by mile anytime after ticketing and you will be notified if your waitlist got cleared usually happen around the departure date.
