( CNN ) -- A travel website on Saturday flashed the word `` CANCELED '' in blinking red letters across an online flight schedule for Missouri 's largest airport after a rash of severe weather stranded travelers across the region . Lambert-St. Louis International Airport , the country 's 30th busiest , was closed after a tornado struck the facility on Friday , but officials expect it to reopen Sunday . `` All departing and arriving flights are canceled until further notice pending full safety assessments of airport facilities , '' the airport website said Saturday . St. Louis-bound flights were diverted to neighboring airports as a result of the storms , including more than a dozen flights to Kansas City International Airport , according to airport spokesman Joe McBride . Rerouted passengers were put up in hotels , and at least three airlines tried to accommodate frustrated travelers on Saturday by busing them from Kansas City to St. Louis , he said .

Friday night , lines of weary passengers wrapped around airport car rental centers in a frantic attempt to find alternate transportation . `` It was pretty crazy , '' said Enterprise employee Daniel Tighe . `` People were getting into Kansas City just to figure out that their flight had been canceled . `` We took in 30 walk-in reservations just last night , '' he added . `` Plus it 's the holiday weekend . '' By Saturday the influx of one-way car reservations had abated as rerouted passengers made their way to St. Louis . `` We had quite a few runs to the Greyhound bus station and train station downtown , '' said Chris Bos , an employee for Nick & Nino 's taxi service in Kansas City . `` Most people did n't complain . There 's not much else they could do . '' AirTran said it will fly its St. Louis-bound passengers to Bloomington , Illinois , or Kansas City , Missouri , according to company spokesman Christopher White . But potential thunderstorms and flooding still loomed over the St. Louis area by Saturday afternoon , the National Weather Service said . Major damage was evident in nearby communities , where an estimated 30,000 homes were without power . See iReport images from elsewhere in Missouri . Meanwhile , 30-minute delays lingered at Chicago 's Midway and O'Hare airports , where severe storms prompted more than 500 flight cancellations Friday , according to Karen Pride , a spokeswoman for the city 's Department of Aviation .
