Does anybody know what the story is with DL 2252, i have been tracking it for the last two weeks and it was on time maybe once. I am interested in it because i am thinking about flying DL from ATL to AMA through MEM and the ATL-MEM segment on 2252 seems to be delayed everyday and i will have no chance of making the connection in Memphis. Any insight on the delays?
