We have the same change and issue on June 15th. After much discussion, and based on experience with this route on prior trips, we are not changing to the later flight. I called Seaborne and they said the gate closes 45 minutes prior to the flight, but this has not been our experience. Can someone confirm that we can walk up 30 minutes prior to the Seaborne departure (assuming our plane lands on time). The later flight currently has plenty of availability as a fallback, but I know this can change.
