In that example I has 0 inventory. You want to find a flight with I2 if you have two passengers.
The site is telling you no availability for Business Saver when you add a second passenger because inventory is I1, so you can't book two tickets (i.e. one ticket is available but two tickets are not available).
Is it likely or unlikely that more Business Saver seats will become available later? Do they allot x amount and when those are gone, they're gone?
