They are not insults if they're true.   Delta did not deny 'stealing' a paid for reserved seat from Ms Coulter and gave no reason for the  'bait and switch'   she should get a full refund, and next time fly another airline, but it's hard to pick any domestic airline that's not just as bad and abusive as Delta.   Customers have to band together and boycott, or else we will keep getting abused.
