I fly 2-3 times per month, sometimes more. This summer, I have experienced an extremely high level of cancellations due to "mechanical problems" with Delta. This week I had two return flights. One from Detroit to/from Reagan and one from Detroit to/from Charlotte. Both outbound flights were cancelled. (flights 1844 and 1442). Two weeks ago my outbound and return flights from Detroit to Reagan were cancelled. It seems to happen when the flight is about half full and by combining it with the next flight the plane is full - although the airline indicates it is never the reason they cancel their flights less than 24 hours before they depart. There appears to be nothing I can do - are any of the other airlines cancelling flights at a 50% or more rate? I'd like to change to a more reliable airline.
