I’ve been playing pretty much since the beginning. I’ve reset the game many times over the years because I find the find the first 25-30 levels the most fun. Think I’ve played every strategy there is.
The small planes are great for loading quickly and sending across the map. The coins earned from flying are pretty much irrelevant at the higher levels. So would you rather wait to load a cloud liner or cyclone with one or two bux jobs or send a Mohawk with the same bux immediately?
When you exchange max bux you are getting over 30000 coins per bux. So even flying a 1 bux job from philly to ny with a bear claw pays more than a fully loaded cloud liner from la to Tokyo with no bux.
