I am curious what happens to delayed flights. Some of these flights get cancelled and then some of these flights get replaced by another flight.
Is there any way to see a list of delayed flights? I am looking for something with the same format as http://flightaware.com/live/fleet/UAL/cancelled
Some cancelled flights show times in red - does this correspond to the time at which the flight was cancelled?
Some airlines seem to use replacement flight numbers to catch-up on cancelled flights e.g. http://flightaware.com/live/flight/UAL1756 . Note that in this case the flight number appears to be used for any sector and any aircraft. Is there a way to identify these (random) replacement flights?
Is there and easy way to assemble the whole chain of delay/cancellation/replacement?
