I'm counting down the days to book a return trip from Thailand and hoping to get CX First award on AAdvantage (for the second time). Last time the date 330/331 days in advance arrived on a weekend and everything thing worked out, but this time it will be mid-week so I feel a need to get my timing down better so I hopefully can get HKG -> JFK rather than flying via the west coast. So my question - will AA see the CX inventory 330/331 days in advance based on the Hong Kong calendar (one day ahead) or the US calendar? Final question - should I be calling near midnight at 330/331 days out or is award space released at some point later in the AM? Update 1/2: Called AA for booking for 331 days out based on BKK time (6 am) agent said I would have to book tomorrow based on Central time.
