Indigo is a Airline services which is running across the globe. The best thing of Indigo Airlines is the cheap fair charges. I am a frequent flier for Indigo Airlines and my experience with Indigo has been very good so far. Also they are running the flights in very frequent manner. One more best thing is you need not to book the Indigo flight before long time, instead you can book 5 to 10 days prior. And the process of booking, check in and boarding is very smooth. And Indigo Airlines is excellent in their punctuality because I have hardly seen any flight of Indigo Airlines is delayed or not flying on time.
