From: US Govt
To: All US flag carriers
Memo: Now you're required to operate x amounts of flights each day out of Kxxx airport, and you will be fined $xx,xxx amount of dollars if you cancel because of the latest DOT rulings. If you operate such flights and your pax are stuck on the ground for more than 3:00, you will still be fined $27,500 for each pax. Oh, and by the way, we're not "regulating" US flag carrier, we're just making sure we're making our tax paying constituents are happy.
