Am flying JFK-AUH on EY100 in the next few days in J, flight seems to be booked quite solid. Have an aisle seat reserved already but trying to see if anything on the window side opens up but so far no luck. However, I see that rows 5 and 7 in J on the 773 are always blocked for every date out in the future I have checked. Does anyone know when these get released or how one can get one of these seats reserved? Is it strictly at the airport only or does once need to call 24 hours in advance of departure time? (I know these are bulkhead/bassinet seats but just wondering if they every get released beforehand).
