TBH all airlines flying to places like the Shetland Islands are non-profit
What can you ring out of any airline to make serious difference?
Lower salaries, nothing paid to shareholders - that's about it
you still have to buy the planes, pay any borrowings, buy fuel, fulfill all the paperwork, stay safe
At the end of the day it's bums on seats, how much cargo you can squeeze in and getting enough full fare passengers to squeak by - profit or non-profit doesn't change these factors
