While on the topic of Row 6, are there any seat/bulkhead configurations in the AS fleet that don't allow space for personal storage underneath F seats in front of Row 6 (e.g. bulkhead extends all the way to the floor)? I guess no seat in front like 6B on an E175 also might be a problem.

Preferring to board last, wondering if I can safely find space for a personal item regardless of aircraft, not having to worry if overhead bins are full.
