This Flyertalk thread has the details on an El Al offer to match bmi Diamond Club status provided you’ve had two or more Tel Aviv flights in the past year.
The offer (in Hebrew) is valid through February 10 and offers 6 months of status — bmi Blue+ members get El Al Matmid Gold, and bmi Silver and Gold members get El Al Matmid Platinum. There’s no match to Top Platinum.
The offer also contains a fast track — earn 800 points in 6 months to earn Gold status for a year, or 2000 points in six months for Platinum for a year.
You need to submit your El Al account number and bmi statement showing two Tel Aviv flights (those flights can be on any Star carrier) — by email to yaely@elal,co,il or by fax to +97237604043.
