I can’t provide you the logic, that isn’t very prevalent in the military or government and it’s actually comical how much congress or other officials fly back and forth from DC to their home offices…or vacation houses.
Maybe the respective branch should provide every person in the military traveling under official in uniform orders a first class ticket, but I’m afraid that will also be frowned upon as pointless spending…and will never ahppen. I can tell you that most airlines will automatically upgrade military personal in uniform to first class if there is room available. So by no means am I attack the industry as a whole.
This is really a story by the media to rustle up some attention, nothing more. Also, with the current threat against military personnel from groups like ISIS, it would be wise for the military to stop all uniformed travel. no sense in giving them easy targets. I never ever traveled in uniform…I always made plans to have a room to change and carried a garment bag so there are other options.
