The link is "who cares" in the letter. It leads to a the only deleted DJT containing who cares which is on 07/04/2019…when then leads to the deleted tweets on "aircraft one" on 07/04/19 at 747am….which is also a qproof as a year before that on 07/04/18 q posted a pic of a 747.
Conclusion whatever aircraft Biden is taking is either a fake AF1 or its all a screen play
