The compensation package at SKY is $14,500 USD/month including salary and allowances, but with the attrition levels that they are experiencing right now (a good friend that recently joined the line there told me that they lost 12 captains in January) the company resorted to offer $1,000USD to fly on their days off, hence the 20K number that has been circling around, it is possible and some guys are doing it but it is by selling several days off to the company.
