The Foreign Earned Income Exclusion has been in

The Foreign Earned Income Exclusion has been increased to $102,100 for 2017, so a married couple filing jointly can deduct up to $204,200. 

 

The excluded amount cannot exceed your earned income for that year, so if you earn $50,000, that is the maximum you are able to deduct. Also, the amount is not "portable" between husband and wife, even filing jointly. So if one spouse makes $500,000 and the other one makes $50,000, they will only be able to deduct $152,100 in 2017 (full exclusion for the highest earner, capped exclusion of $50,000 for the lower earner).
