In essence no.
BUT, getting the license is the easy part - the most difficult is landing the job.
Who you know certainly helps... but believe you me - you will find many that will dangle carrots in front of you but then are never able to help or will help.
Those that I know who have gone to OAA, CTC have the back door route without even applying to the airlines. They have them lined up for them.
EZY, MON are some to mention, BMI regional etc.
There are a few limited ones who dont, but minimal.
If I had to do it again - it would MPL with a reputable school period.
Good luck....
