NRT>EWR wait for saver?
I'm looking to use miles to purchase two economy tickets around January 8 (+/- a day). There's currently no saver economy availability, but I can get the seats for 80k each (which is the same price as business saver, also unavailable). Is there a decent chance saver economy will become available between now and then if I keep checking, or should I just go ahead and spend the 80k each on economy?
