Anyone have any recent tips on booking four business class seats to MLE from the US?

For the outbound, I managed to snag flights through CMH-BOS-DOH-MLE. 2 in business and 2 in economy. Its apparent from additional searching that only two business class seats were released by QR for each of these segments. My hope would be that two additional business class seats will open up before departure next year. Can I set up an alert for this through expertflyer once the data feed is working again? And what is the latest on how often additional award availability is released for business?

My fallback would be to just buy the two extra seats if/when there is a sale. But I'm thinking I did not do myself any favors booking through BOS. Unfortunately there was no availability I could find ex-ORD or JFK, which tend to have cheaper fares.

I would appreciate and thoughts or guidance. I will be booking the inbound soon.
