Your delays are surely due to severe weather the Central U.S. is experiencing today-- thunderstorms and tornados. Since those are out of the airlines' control, they are unlikely to offer any compensation-- in these situations, sometimes even meal and hotel vouchers are hard to come by.

BTW-- the average arrival/depature delay at ORD is 5-6 hours this afternoon, according to ATC.
