Dodo Airlines is completely new to the series. It basically replaces the train in other games.

Which means you can travel to other islands by air.

The easiest to travel to is the random islands from the single player only mode of the game.

But all these islands are rather boring and lame.

The best part is to travel to the islands of other players and see how creative their islands are.

The only problem is everyone has to be online and have their gates open. And there is rarely a good balance. You either have no one come to your island, or the island gets flooded with so many visitors but nobody can play because it stops the game temporary.
