Hi,
Do not think about salary as a first officer in Indigo. Even if it is slightly less initially, there would be upgrade from junior co-pilot to co-pilot and then senior co-pilot in the company. Also in approx 5 years down the line you could get upgraded as a captain.
Worst come worst in present scenario it is the best airline in India to work and there salaries are also on time.
So if you can make it to an Indigo cockpit it would be a great thing.
And 9FLY , I believe his question is valid. There are people in India who believe in spending there parents hard earned money wisely and there are the rest like you. So please give space for others too...
