Just a note to watch the actual timings in your itineraries carefully if you have connecting flights booked.

I'm pretty diligent checking the itineraries at delta.com usually, but just noticed today when looking at all the flight times again for a trip this Friday there had been a schedule change that was NOT denoted in the itinerary (hence why I didn't notice til now).

Worse still, the system not only didn't note the sched change in the record, it also had me on a mis-connect to the last flight of the night through MSP (29 minutes for domestic-international, minimum is 40 mins).

Luckily there were still seats on an earlier flight that I was able to get them to reprotect me on.
