Hi-
Wondering if I can get some advice here - I'm looking at booking 3 1 way tickets from BOS to Sydney for January 22,2015 - I've been watching the availability and consistently find 3 Business and First Class seats available via Asiana from JFK to Sydney - I have no issue getting to JFK from Boston - Knowing that availability to Sydney is difficult at best, next to impossible for 3 people and knowing that the devaluation is coming up before my fights will become available for ticketing - Is it worth me booking the 3 tickets now from JFK to SYD and then having the ticket date changed once the flight is loaded? Or am I setting myself up for failure - I'd really like to get these tickets before the devaluation and would really like the First class if thats possible.

Any thoughts/Options? Does UNITED ever open Business or First on their own Metal to Sydney? Are there any other options?

Any help is greatly appreciated!
