I carried a journal during my trip to keep the notes of the trip and also a count of my daily expenses. I would share my entire trip here including the expenses occurred. Hope this would provide you with a fair idea on how you can travel cheap, safe and long.
Day 1 (New Delhi - Bangalore - Colombo - Chennai)
My flight's scheduled departure from New Delhi was 8.35PM but it got delayed by the half-hour. This delay caused another problem for me. It was a connecting flight. I had to board another plane from Bangalore to Colombo and go through the immigration and security checks. All this was time-consuming I felt I would miss the flight. The boarding time was 12.30AM and I reached the queue for immigration clearance at 12:20 AM. Thankfully, the JetAirways executive expedited the process, sorting the issues with airport authorities. And finally, I was in the plane.
