Here’s a helpful tip. Book a flight right NOW. Don’t wait until selection show. Most airlines give you 24 hour cancellation on any flight. You can cancel with 24 hours (or midnight tomorrow on Delta) if you have to. Also. Flights to Phoenix very high priced right now from Atl. Reasonable to Tucson. Not a bad drive. Did it last time.
I will be there. Enjoy the ride and travel if you can.
