A solid amount of flights out of SFO end up delayed for various SFO things; ATC congestion, bad weather, etc. On DL, almost every delay triggers the “select alternate flight” feature of the app.
I’ve used this feature several times to get more MQMs/MQSs but I’m curious where the rules for what you can re-route to come from.
For example, I once changed SFO-BOS to SFO-LAX-JFK-BOS. (DL then paid me 10k miles to switch back to SFO-BOS because of overbooking.) How does the app decide what routes I’m allowed to select?
Also, is it ever possible to add a stopover? In my current changed routing, I changed SFO-SEA-CVG to SFO-SEA-ATL-CVG. But would it ever be possible to add a stopover in SEA?
