Hi I am Pradip Narayan Madgaonkar coming from a small town in Ranchi. A passionate travel enthusiast working in the finance world and a regular at using apps like Skyscanner and LonelyPlanet. I am a writer and an even better photographer. Due to my job I have had the opportunity to travel to amazing places within India and abroad. Frequent and short Travels keeps me calm and helps me to manage the stress from the finance world. “If you think adventure is dangerous, try routine, it's lethal” - Paul Coelho

You could use any of the following: travelling companion / travelmate / travel partner. Myself, I would probably favour "travelling companion". Edit: As several people have pointed out, the word "companion" alone would be sufficient.
