Had a first. Flying with my wife today. We were upgraded via RUC a few days ago. We were initially upgraded to 1A and 1B (the only set of two together), but my wife hates bulkheads so I moved her to 3A and me to 2B. When I checked in last night, that's what we had. When we got to the gate and my wife pulled up her boarding pass via the Delta App, it showed 2A (and the machine spit out a receipt for 2A when she scanned her phone as she boarded.)

Wonder what happened. We didn't ask anyone to swap us. Did a GA notice we were traveling together and move the original occupant of 2A to 3A and put her beside me? Or perhaps 2A misconnected or switched to another flight and the GA saw 2A was open and moved her beside me? Odd that it happened without us even being asked or is inquiring about it.
