Meeting planners' growing use of low-cost carriers such as JetBlue Airways and Southwest Airlines is a trend that will continue into next year, although the secondary airports that such airlines often serve are less popular. Successful Meetings' March survey of 160 meeting professionals revealed that 29 percent of planners will increase their use of low-cost airlines in the next year, although only 15 percent will increase their use of alternate airports. And a plan by the Federal Aviation Administration to delay flights at smaller airports this summer in order to keep traffic flowing at larger ones will likely reinforce planners' preference for primary facilities located in metropolitan areas.Laurie Mask, a national account manager with HelmsBriscoe in Tampa, FL, says that there's a limit to the hassle attendees will endure to save on airfares, and alternate airports that require long drives to meetings venues push that limit. "It's a question of how much money you want to save and how much your time is worth," she says. "For instance, if you're dealing with the traffic in New York, it's worth it to fly [directly] there."
