I am an Alumni from OU myself and went through the aviation program. I ended up double majoring in aviation and business. The thoughts that you have with getting a fiance degree and aviation, is probably a super smart idea just in case something goes TU in the aviation world and you are stuck w/out a flying job.
I wouldn't get too hyped up about the CFI jobs at OU, cause at this moment in time there is no movement anywhere but in 3, 4, 5 years, when you get your CFI, it could be a totally different story.
The bridge program at AE is definitely a good thing to experience and at least get your feet wet in the airline industry. However, I wouldn't put all your hopes and dreams into getting a job there. Not that you will not get hired but their upgrade time is ridiculous at the moment. No offense to the AE guys cause I have a few friends there at the moment.
I worked at XJT and unfortunately I am furloughed but hoping that my recall letter is coming in the mail soon. Maybe when this industry starts going full steam again that movement within the regionals will begin to happen again.
Overall, I don't think you will find a better school for the price. I had a few friends that went to some of the Florida schools and are in some serious 6 figure debt and I managed to get out w/ half of that. They now have a new fleet of warriors, which i didn't get to experience
. The school is great and you will definitely get a top rated education. If you want to talk or ask any other questions about the program just ask. I still have a handful of friends in the aviation department.
