The advantage of Plus one is they have excellent availablity and don't get the aircraft clogged up with students. They also have so many aircraft that if one goes tech you just grab the next one in the line.They have 8 172's plus a couple of 152 They also refund fuel at full price (not $2/gall as most schools do). The minimum you need to fly is one hour if you book the ac for a whole day and if you book less then there is no minimum.
The planes are nice, not tired old school planes.
If you hire a school plane and it goes tech will they have avilability for the rest of your hol.
Plus one also have a duchess at $140/hour, go and do a twin rating.
What ever you do have a good time, the states are an excellent place to fly.
