One thing NO-ONE, either the majors, regionals or any carrier teach, or instill, is the ICAO radio phraseology handbook/how to talk on the radio!!! Delta is about the worst I have heard around the world. Btw, 123.45 is NOT for idiots to discuss contracts. If everyone would take the time to read the ICAO Handbook the world would be a better place. Don't see it happening!

Hears three for free;
1)Cleared for Take off! Not cleared to Go
2) Climb and Maintain FL 35 ZERO not 35 Oh!
3)Vacating runway 25L not clearing!

You're welcome. Never miss an opportunity to ****!
