There's no relief for someone with an airline background at this point. To be eligible to take the ME ATP written, you need the course. ERAU has one for its students. Higher Power (recently bought/merged by/with ATP) is developing one, according to its newsletter. I'm sure others, such as Pan Am, are doing the same. I don't know of a course that's up and running and available to the general public.
