That is an interesting point. I live in the Baltimore area. We have just three flight schools around here. At least three close enough to where I live. I am currently using one of the three, which has just two 172s and other three really old planes. Schedule is so busy that I had to restart my instrument program twice despite I booked plane and instructor two months in advance. Every time it seems to me that they purposely delay lessons. I must say, I am with them now cos Iam part 141 and I neeed to finish with them (check ride probabily this weekend). The other flight school is for amatours, mam and pap kind of school. Even older planes.
At BWI the last option I have, It is a kind of snobby. A lot of delays cos the school is on one of the busyest airports. I am actually considering them as next step anyway. To answer to your question, why accelarated program? well I am 33 and as you know at 33 it is about the last chance I have to get THERE before my granchild get there . The job I am doing to pay the flight school, really began to make me sick. that is why fast track program. I want to change job, become instructor and from there ...well whatever can make me fly.
