A 100% increase in local pilot salaries may not be all that much depending on how badly paid they are in the first place.
Unfortunately the pay cut sets a bad precedent for the rest of us in this part of the world and I'm sure we'll hear "You're lucky we're maintaining salaries, other airlines are cutting them.'' at our next pilots meeting.
A rapid voting with the feet and the resulting flight cancellations would be the best outcome from our point of view as you can bet management at other operators are waiting to see if VNA get away with it.
India is slowing down for expats, but the sand pit should still be worth a look.
