Advice Regarding Booking First Business Class Flights

We've been traveling by economy class from Baltimore/Washington/Philidelphia airports to various airports in Europe for the last ten years. It is miserable, but we have never been willing to pay what amounts to another whole cruise cost just to fly to our destination. We could have managed it financially, but it would have cut back on the number of trips we have taken. Now, for the first (and only) time, I am looking at a cruise from Bangkok to Mumbai. I know I cannot manage flights

Thanks for the advice. I do understand the pricing issue for a trip that far in advance. My problem is that I think I will only book the trip if I can figure out an acceptable way to get there. We have only traveled East Coast to Europe so far, and suffer through economy seating on those. That is not an option for going all the way to Bangkok for me. Neither is paying as much for the flight as we are paying for the cruise. I am just trying to get some information since this is all new to me.
