Comparisons between Indian Domestic flights

Comparisons among Indian Domestic flights:

Common things for each flight:
1. We have to reach approx 2 hours before the departing time of flight/
2. We have to first check in either web check-in or counter check-in.
3. We have to present 25 minutes prior on the boarding gates in any way if we don't want to miss the flight.
4. You should have one photo id card (issued by some govt. institution or gov. org.), Passport, voter id, driving licence or Aadhar card will work, I assume.

5. Baggage: There are two types of baggages:
a) Checked Baggage b) Cabin baggage or hand baggage.
6. Baggage limit will be 15kg(checked-in baggage) + 7kg(cabin baggage).
