The wife made it up to Delta Diamond, or Platinum, or whatever it is, for a year. That was really nice. She is very committed to Delta for some significant reasons.
It's good that they have some flights out of ATL. I usually get to Silver which gets me ... almost nothing. We upped to the Amex Delta Reserve cards which get us into the lounge and one free companion ticket, which can be in First domestic. I splurged on First to SF with that. Of course, First is not really much of a deal on domestic flights IMHO. I need Economy Comfort because of the leg room.
I think Boeing is suffering with the 737 Max grounding but their stock price has not collapsed. The wife worked for the outfit that makes engines for that.
