How many of you guys used an application review service? I just signed up for the one with Aero Crew Solutions so kinda curious how effective it is.

Trying to get on with one of the Big Three, United being my first choice for the drive. 7300 total, 2300 TPIC, ex-mil (non-aviator) Master's. Currently FO on the 190 at JetBlue and bidding over to the Bus hopefully. Not sure where I stand with the competition.
