Question...does anyone know what would happen in this scenario?
Hold IHG card that gives 10% back on points
Have regular Ambassador in 2018 without extra rebate bonus on point use
Book 140k worth of stays in 2018 for 2019 date that is in 2019 Ambassador year\
When renewal time for 2019 Ambassador year comes, pay for Ambassador version that has 10% rebate on points
Will the stays rebate 20% when they post in 2019 even though the booking was made in 2018, but the actual stay and credit card rebate will not trigger until the 2019 year?
