From their blog (http://planered.tumblr.com/):
We’d like to get subscriptions down to $150 a month. In fact, we’re guaranteeing that rate to some early subscribers, and the top PlaneRed.com referrers.
But, if at that rate we just can’t put enough planes in the sky to meet demand - we’ll have to charge a little more on the subscription - or add a small $25 cost for each flight. (We know - that ruins the ‘all you can fly’ but we’ve had several folks make passionate cases for doing so.) What do you think? Which would be better $250 a month, or $150 a month, and $25 per flight?
