Interesting diversion back to PDX by brand-new Horizon E175 (regional jet) N670QX. The plane did its delivery ferry flight from the Embraer factory in São Paulo, Brazil to Horizon's maintenance base at PDX on Friday. It started revenue flights Tuesday. Today when @JetTip alerted me to the diversion, the tail number looked familiar. Since it's scheduled to retry the flight to Billings MT (BIL), it wasn't a maintenance issue, at least nothing big. Maybe a pax issue. #KPDX #aviation #travel #avgeek
