No formal notification yet but upon checking my Delta return flight for March, it has been changed and would now require an overnight in ATL. I also checked AA and they have eliminated some of the later night flights and for a friend flying AA back into DAY, the connection time is now 1h 14m, which I highly doubt will work.

The March trip is very likely not going to happen for me. Way too many changes and hoops to jump through and potential government B/S on both ends.

Check your flights and do NOT rely on airline notification. Depending on your airport, you may or may not be ok.
