There are many ways to travel and some are better than others. Both planes,helicopters and hot air balloons all have their advantages and disadvantages. I would say out of the 3 the hot air balloon is the worst. It’s only advantage is its more eco-friendly, other than that it is significantly slower than both planes and helicopters. Also you have to use and pack more food because you’re slower and you have to have an individual hot air balloon for everyone for long distance travel and it makes it worse than flying a plane.
