Oneworld Alliance

From Erik...
As far as I can tell, airline alliances are important to frequent travelers. Frequent fliers accumulate miles and sooner or later they spend those miles. In addition, frequent travelers enjoy special airport lounges and in some cases faster security. Flying with airlines within the same alliance provides more options to spend miles in terms of destinations, priority routes and on board accommodations.
