Yelp generates revenue mainly from local business advertising, display advertising and from additional services like Yelp deals, and deals with reservationservices like OpenTable.
This suggests that, while OpenTable is already the single largest provider of online restaurant reservationservices, it is also witnessing almost 40% annual growth in the number of diners it seats.
Under the likely deal, designated American and Japanese airlines will be able to link their trans-Pacific services to flights provided by third-country carriers, sharing flight numbers and even aircraft and reservation systems.
