American brings back double elite qualifying miles through December 15 — the second time this year — registration is required.

The same registration page will also let you sign up for elite rewards for stretching beyond the minimum qualification for an elite level…. a choice of benefits like extra systemwide upgrades for Executive Platinums, bonus miles, or 500-mile upgrades for Gold and Platinum members.

Signing up for both offers is a no-brainer of course, a few incremental unplanned trips and you may find yourself in a higher elite tier or qualifying for a bonus award.

Randy Petersen points out that the ‘elite rewards’ are a response to Delta’s rollover miles, both of which encourage members to continue flying the respective airline after hitting their requalification needs.
