People that say on the radio, Orlando approach, Connection 209, 700 for 1500, runway heading. The word "for" can cause confusion when combined to certain numbers.
Here's a better method. Orlando approach, Connection 209, 700 climbing 1500 runway heading.
And god forbid you say "with you" or "checking in" if I'm within hearing range of your dumb@$$. "With you" turns into witchyou, and checking in, hell, they know your calling them. No need to converse extra crap. Trust me, YOU DON'T SOUND COOL!
Better - Daytona approach good afternoon, Connection 209, 4000. That's all that's needed. Short, brief, polite and professional.
