Some one correct me if I'm wrong but I believe Compass' certificate was from ACA/Independance. The reason why it took Compass so long to get certified was because they let the certificate expire. I believe you have to have so many flights in a month or something like that. So if the ticket did expire.....no airbus, crj or anything. I also believe the ticket is aircraft specific, so if you don't fly that type of airplane for so many days it comes off. I picked up most of this when I went through the shut down at Skyway, don't take it as a reg. but thats what I gathered from everything.
