Emailed them online with my request. Got this answer
Thank you very much for your message dated 31 March 2016 in which you inquire if we have a status match campaign.
Thank you for taking the time to write to us.
Please be aware that at the moment the Flying Blue programme does not offer a status match for other loyalty programmes.
Nevertheless, as our programme grows, we hope to offer this possibility in the near future. As soon as this will be available, you will be informed via e-mail and/or it will be advertised on our websites.
Should you require any further information, your Flying Blue team remains at your disposal by telephone.
