Alright folks, here's my situation:

Corp. pilot, been updating an application for years, and finally got the interview invite a couple days ago out of the blue. I have an interview scheduled for the end of October- so I have a lot of prep to do, and need to do it fast!

Is there a consensus on which prep service is the best for Delta Air Lines? I did a quick search on the forum and the results I found mentioned Aero Crew Solutions, Centerline, Emerald Coast... but all the info was years old. I understand I should use RST for the tech portion.

I am an Emerald Coast member, so I can go back through their course fairly quickly at no additional cost, but I'm not against spending a bit of $$ if another service is "the way to go".

One more thing... how accurate is the info I hear about "blue suit, red tie"? Does it matter at all, or can I use my black suit I've worn maybe 4 times..?

Thanks folks.
