Review of SATENA flight from Medellín to Bogota in Economy

I decided to fly from Medellin's Enrique Olaya Airport as I can save some time and few pesos as it was located inside the Medellin city compared to the Jose Maria Cordova INTL airport which is located far from Medellin city. Only Satena airlines offer flights between EOH and BOG route. Heard that this airline has frequent cancellations and delays. Check in was smooth but as per reviews my flight which has actual departure on a 12.32pm was also cancelled and I was later accommodated on 3.00pm flight, so my purpose of saving time in the commute to airport was ruined. My flight was operated with an ATR42 aircraft, it was very old and the aircraft's cabin was dirty.
