July, Aug. 2002: Two bridges in Central China collapse, killing a combined 19 people. Sept. 2001: The Queen Isabella Causeway in Texas collapses after a tow boat captain loses control of a string of barges and currents drive them into a bridge support.
The average flying time for a direct flight from Bemidji, MN to Chicago is 1 hour 36 minutes; Most direct flights leave around 9:36 CST
Usually 90 minutes is sufficient time for check-in and then they board 60 minutes before the flight. Well, my family goes wayyyy early but typically you should arrive 6:00, i guess. but i guess a little later is fine but just to be safe leaving a little more than an hour is good.
