Should I book a flight using the Student fare or not then?

I am a student,
who is allowed to carry 25kgs as check-in bags.

I want to carry my guitar and 2 check-in bags, as they are medium sized.

I was skeptical about Guitar but then I read this:
"Musical Instruments: Carriage of musical instruments is allowed in our Domestic and International flights at no additional cost. Guitars, if packed in soft cases, can be carried in hand baggage, however, other instruments have to be properly packed and can be carried in Check-in baggage only."

I am, now, worried about luggages...

I don't want to travel in AirIndia because they have mentioned that I will have to book an extra seat for my guitar...
