I don’t think Hunter EVER flew on AF1. If he did, it would have been when dad was VP.
Speaking of which, since 1/21/21, dad has NEVER flown on ‘AF1’. Following ADS-B sites, one learns and knows that ANY flight with him on it has a call sign of ‘N/A’ or ‘SAMnnn’, or similar.
Yes. It’s different now.
His son flew all over with Biden, eg to Beijing, when Biden was VP.
