We have 3 tickets DEL-ICN-LAX in J for end of April and was able to select seats online. However, there are very few open seats and I find it hard to believe that so many would be taken so far ahead.

On the DEL-ICN (A333), only 4 seats are open (out of 30) with no window seats available. On ICN-LAX (A388) none of the "buddy" middle seats are open. I would ideally prefer to select one of the 3 pairs in the front Biz section. I know OZ blocks a whole lot of seats, does anyone know which ones they block for these aircrafts and when are they opened?

thanks....
