Review by Bob Rossney.
Airlines is a game of network-building and speculation.
The game board is a network of cities connected by routes. Each route has one or more circles on it, indicating the number of different airlines that may use the route before it becomes closed. Each airline can fly in a specific set of regions. Finally, there are two decks of cards. At any given time, an airline is owned by the person who has the largest number of corresponding stock cards in front of him.
