There are agancies who provice free air tickets if you work as a courier for them. You might even get a small sum of pocket money and eventually a free hotel room.
I was interested in the possibilily of free travel and have contacted and registered with the agency "timematters" in 2019. As I was working fultime in my main job and and in 2020 there was Covid I never had an assignment. In general there were not many offers. But when the pandemic ends, I have more spare time or there are job offers during weekends I might very well apply for one.
Do you know other agencies and have experience with them?
