Same question was discussed on a facebook pilot thread one or two months ago, so data is probably still decent:
46 yo male, 20 yr term for 1.5million = $230/month (Prudential)
42 yo male, 20 yr term for 1.25million = $700/year (Zander)
41 yo male, 20 yr term for 2.5million = $170/month (Selectquote)
The above three were either flying part 121 or part 135
Someone also recommended Northwest Mutual but didn’t say what they were paying for their policy.
