I plan on booking a trip on September 1st (~127 days from now) ASAP (to avoid higher fares) and want to get the referral bonus for the second passenger, but we can only get the referral bonus if we travel within 90 days of referring her. Is there a way to book the trip 91+ days in advance AND get the referral bonus? I'm thinking something like booking now, then once the 90-day window starts, signing her up and getting her AGR # added to the reservation? Would that work?
