Sorry guys -- I was out of town for a few days and not online.
The overwhelming reason why I never deriously considered Flex when I originally went with NJA was $$$. Until recently, when you purchased a share in your jet from Flex you owned it for 5 years (the term of the management contract). At the end of the 5 years, you sold your share back at its current value and then needed to buy a new share at at the then current prices. In other words, you needed to cough up much more $$$ to fly in the same planes. They admitted to doing this to sell more planes for the parent. With NJA, you continue to own your share and at the end of the 5 year term just pay the new management fee. No need to cough up more $$$.
Example, you put $1,000,000 into a share for 5 years. After 5 years, you sell your share back to Flex for 70% = $700,000. A new share in the same jet is now over $1,200,000. To continue flying the same fleet, you need to come up with another $500,000. This cost Flex many sales. I believe in the past 1-2 years Flex elimiated this and made its strructure more like NJA's.
Reason #2 was what I would call "depth of the fleet". I fly in and out of a small Rocky Mountain airport several times per year. I am friendly with a Flex owner in the area. When there are last minute mechanical problems, it is not uncommon for himn to wait 6-8 hours for another plane. Just not enough planes in the neighborhood. My delay is usually 1-2 hours out west, minutes ont he East Coast. The ability to get a replacement plane to out of the way locations has been a problem (according to the few owners at the others which I know) for CS, Flex, FLops. It is not a problem along the East and West coasts, but can be in the middle of no where.Fly safe.
