Air Berlin is offering to status match other airlines' frequent flyer programmes when members join its Topbonus scheme.
The German carrier said the match is only available for its Silver and Gold status levels and the Oneworld member is unable to status match any of the alliance's other airlines.
To qualify, frequent flyers must first register for topbonus membership and then request status match in an email to [email protected]. This email must include a Topbonus number and a "legible" scan, photo or copy of the member's other valid frequent flyer card.
Each member's application will then be reviewed and processed, Air Berlin said.
Approved members will be awarded the corresponding status with Topbonus for a probationary period of a year.
Within this 12 months probationary period, members will be awarded status for a further year after reaching the "required number of status miles or flight pro rata".
Silver status is awarded after collecting 25,000 miles or 24 flights within 12 months, while Gold status is awarded to those who collect 50,000 miles or 24 flights within 12 months.
Platinum card is excluded.
