Balances are normally preserved in some form
The airlines usually announce how existing miles or points will transfer. A one-to-one conversion is common but is not guaranteed in every structure.
Elite status has to be mapped
Members may receive a comparable tier in the surviving program, sometimes with transitional benefits while qualification systems are aligned.
Award charts can change
Even when the numerical balance survives, the cost of rewards may differ under the new program. That can increase or decrease the real purchasing power of the account.
Partner access can expand or shrink
A merger can move members into a different alliance or partner network, changing which airlines are available for earning and redemptions.
Co-branded cards may be replaced
Bank partnerships often need to be consolidated. Cardholders can receive new products, earning rules or benefits as contracts are renegotiated.
Members should follow official integration notices
Speculating too early can lead to unnecessary redemptions. The important details are the announced conversion ratio, expiry treatment, status mapping and timetable.
