Like others above have said, The best way to check award inventory is the BA site. The info on BA is real time while others above have mentioned that the calendar view on the JL site is only updated once a day around 10:30am PDT (timing varies widely day by day...can be anywhere from 9am PDT to 12pm PDT). The real time inventory on the JL site is only available when looking at specific dates.
Released at 10AM JST, 330 days out. But does anyone know what time they periodically release seats after that? Does the same 10am hold true? Looking for a flight that's 2-3 months from now. Using BA Avios.
Or would it be basically 9am~12pm PST since BA is real time?
