What was your most life changing travel experience?

Lately, I booked a Search go cab from Delhi Airport taxi to Greater Noida it cost me hugely so I was expecting a decent service. After 5 minutes of booking ride, the driver arrived & I was on board. So, the first impression of the cab was good I mean there was decent smell and the cab was clean. As the ride was going to take more than 1 Hr so these things really mattered.
