Same day change: AS operated codeshare to AA prime?
Hey! I'm currently booked on a flight which includes as a final leg a codeshare flight on AS metal from LAX-YVR. Have a 6 hour standby in LAX. AS flight has an AA codeshare, if that helps.
Additionally, there is a flight which is operated by AA from LAX-YVR, same day, except 2 hours earlier.
Is it possible to do a same day flight change at LAX, switching operating carriers, or is this not permitted? I haven't been in such a situation before.
