Airfares are priced on the basis of demand and supply. So, when demand is more and supply is less, airfares will automatically go up. Hence, booking flight tickets on weekends is never a good idea. Airfares usually go up on Fridays and start falling on Mondays or Tuesdays. Usually, Wednesdays and Thursdays will have the cheapest airfares during the week.

You can avail rail travel insurance when booking tickets online from the IRCTC website or even through its mobile app. The railways has started giving free accident insurance to those passengers who book their tickets through the online mode.
