Hello!

I am a new regional pilot (about 100 hours of Part 121, in a non-united wholly owned regional). The application requirements on the United website specify ATP minimums with 1000 turbine time preferred. I have a few question application wise:

1. What is a good time to send in an application? is sooner better than later?
2. Will a speeding ticket from 2010 and 2014 (no DUI, no suspensions) make a difference in the application? I plan to mention those of course.
3. I have recommendation letters from regional pilots and AA pilots, is it a huge benefit to have letters from United pilots as well? Or just a nice to have?

Thank you for your kind input!
