If I want to fly out on 12/31 of next year and there is F availability, can I call VS and place a hold for 12/31 in F and then (for example) 1/4 in Economy and then keep rolling my hold until my target return date is available for booking (ANA shows availability)?
For example, I'd hold 12/31 F over and over and economy on 1/4 until 1/12 opens up and then change my hold immediately to that flight in F assuming ANA still shows availability. Is this possible?
