How To Credit Miles Retroactively – Sharing Cost Flights and Hotels

Who doesn’t know this situation? You’ve added your frequent flyer number to your booking but still haven’t gotten your miles. Or you even forgot to add the number. Both things are not a problem, as all frequent flyer programs allow crediting miles retroactively.

Depending on the program, you can credit the miles up to 12 months after the flight. Most programs, however, only allow this up to 6 months.

The requirements differ quite a bit. If you’ve flown with the airline that is directly linked to that program (e.g. you flew Delta and want to credit the miles at Delta SkyMiles), it can mostly be done online, quickly & easy. It gets a bit trickier with partner airlines, as you often have to send additional documents (e.g the original boarding pass).
