Well, a merger you combine not only your frequent flier programs, you do code sharing, you integrate your labor groups, your work rules, and you combine your systems, and we have seen that over the last decade there have been 22 mergers, and they have all been abysmal failures, and airlines have learned from this by doing a marketing or code sharing or a frequent flier program. You get 60 to 70 percent of the revenue benefits and none of the headaches, so that's why these alliances have proved so popular. Let me just give you one statistic. And that's how powerful and beneficial these alliances are for the bottom line of these companies. If you were a passenger on USAir, after they bought Piedmont, in 1987, and were stranded when crews didn't show up and flights didn't get routed, you believe that they were a failure.
Alliances are different.
They are virtual mergers, if you allow the phrase. They have none of the problems of union integration, and all of the convenience of simply being at the same airport at the same time. USAir is still in debt because of the mergers it went through in the 1980's. Dr. Maldutis, pluses and minuses for consumers. The pluses and minuses for consumers.
