On EK435 there are 4 blocked seats, all of row 26. There are four further empty seats available for assignment now, everything else is reserved. That flight will be almost full or full in J.
On EK61, row 6 is blocked. Availability is J1C1IC so that has a chance of being oversold as F looks empty. Make sure your QF Plat number is on your booking as you may have a shot at an upgrade.
Three weeks and group cancellations can change a lot...
