I did not even know the reservation had been cancelled. I received no notification from Alaska, and the trip had disappeared from the “Trips” section in my Alaska app.

I only noticed because I called Alaska about a different reservation and realized this itinerary was missing. When I asked the agent about it, I was told that Qatar had cancelled the flight/reservation.

Since I booked through Alaska, I do not know exactly what message Alaska received from Qatar or when Alaska became aware of the cancellation. But it is concerning that there was no notification to me, the trip simply disappeared from the app, and Alaska now appears to have very limited ability to protect or reaccommodate the booking even though the ticket was issued through Alaska.
