FlyerTalk has reported America´s major airlines could lose over USD 300m in yearly revenue (from a USD 8.5bn budget) if the United States Postal Service were to become insolvent, the news source said.
According to a statement by the US Postmaster General, the mail service chartered by Congress could lose as much as USD 9 billion in fiscal year 2019, and 2020´s loss could approach USD 11 billion.
