+1. There is A LOT of business class availability in CZ for now, and most reviews of the LAX-CAN A380 business class seat are pretty positive. Positioning to LAX might be impossible if you're trying to fit it all into one 120k Delta ticket (per biz class roundtrip ticket); it might be better, especially if for your honeymoon, to splurge for United PS in business JFK-LAX-JFK, which has fairly good advance availability (and IMO is better than Delta's JFK-LAX service). You could even spend some time in LA if you want.

I'd save the money on a booking service here, as this is a fairly simple itinerary. That money is better spent on an expertflyer subscription (or KVS if you're more fluent in travel search tools). However, if you want to do absolutely no work and/or want some creative suggestions on how to really stretch your honeymoon with stopovers/openjaws (e.g., you could use 100k United miles to fly JFK-LAX and back in business, and then 240k Delta miles to fly to Maldives from LAX and back, OR for the same # of miles you could do all of the following in business: JFK-SFO (Enjoy) + SFO-LAX-CAN (STOP)-MLE (ENJOY); MLE-CAN-LAX (Enjoy) + LAX-JFK (END)) then it makes sense. If time is of the essence (don't know when you're going on your honeymoon), then it might be worth it to use a booking service as well.
