Indigo is one of the most less fair flights. I usually travel from delhi-kolkata by indigo as my relatives stays in kolkata. As the price is very genuine so you cant expect it to be 7star or out of the world. It is not much luxurious or astonishing but yeah it is punctual and is fair enough for the price it charges.The meal they give is healthy. the staff is also nice and helping which is the most important thing in an airoplane as you cannot take help of anyone and they are the once who gives you satisfaction. The seats are not that much comfortable but as my journey is of 1.45 hr only I can adjust for this much time very easily. I would suggest you to take indigo as an option only when your journey ia not too long or you dont want to spend much amount on travelling.
