What am I doing with my Alaska miles?
I had cleared out most of my Alaska miles on a number of sweet spot routes in the past few weeks (for travel in 2023) and will probably continue to keep those bookings.
Bottom line
It was a false alarm after all.
This non-devaluation news does not mean that a devaluation will not come in the not-too-distant future. In fact, because of the amazing sweet spots, I’ll be very surprised not to see a devaluation in 2023.
Alaska had also mentioned previously that they will allow members a 3-month notice before any devaluation.
For now, enjoy it while it lasts!
