How does the duplicate booking killer work?
I've not had a lot of experience with Alaska's duplicate booking detection / killer; can anyone share some anecdata on how it works?
By "duplicate booking" I mean booking the same or impossible routes, eg, two one-way transcons with same routing & different departure times on the same day. "Impossible" in the sense that no pax could make both flights.
I feel like I've unintentionally done this a few times. Only once did Alaska step in and call me; I got a kind voicemail asking me to cancel one, a few days after booking. Based on that, I gather (a) it doesn't happen automatically, and (b) it's pretty lenient when they do detect it.
Context: I'm in a situation where I want to book a backup transcon for the same day, and (within a day or so of departure) as a 75k cancel the one I can't make. Not sure how fast and loose others have played it here. Thanks!
