I've been almost in the same situation, and what I've been doing all the time before it - flying as often as I could, for visiting my fiancee. Anyway, it was not hard, because I knew for sure where to get the cheapest business class airline tickets ( url: https://airbusinessclass.com/first-class ). This resource have dozens of airline operators databases, which can offer a customer the cheapest ticket and dozens of options how to choose the specific destination.
