Indigo airlines is one of the airlines which provides cheap air tickets and deasent service.The recent sale was the best time to save extra money.The indigo check-in counter staff was deacent but some times they provide wrong information in case of delay or cancelation.As per I guess this is done by every local airline company.Indigo also offers International flights.The best deal I got was PUNE-BANGLORE for 1350/- which is a grat deal.Even sleeper volvo bus ticket cost more than this.I advice anyone who spends much on bus tickets to have a look on airline ticket too.This will save their time.
