And this is proof that even if weather is NOT a possible issue (certainly is in Buffalo in March), there are other factors to keep in mind that affect flights, even the first flight out - mechanical issues, crew issues (the assigned crew not getting in in time for their mandatory rest and there not being a replacement team, a crew member calling out sick and having to wait for the replacement, etc.), the equipment not being there if it was coming in from somewhere else, delays for computer or weather reasons in the originating cities, etc. Flights going off on time is not as simple as "there's no weather here", sadly.
