I am a graduate of the Uni of Newcastle masters in aviation management, I did this course correspondence while working full time as a LAME. Despite these challenges I was able to finish the masters in 18 months.
Finding time to study and write papers after work can be troublesome however the content of the course was good as were the opportunities to network with people from other sides of the industry/globe.
My qualifications have been well received by employer's (although I did not go for pilot jobs) and have recently helped me gain a much better position lecturing in human factors for engineers.
