This looks great! I would encourage you to be more up-front about the fact this is apparently only for US airports at this time. The experience of entering airport codes and having to guess that it's US-only is a great way to sour future could-be users.
Also, the FAQ shows me "Select from available 3, 7, 14, or 21 days. " while the lander says "2, 3, 7, or 14 days" and the actual hold page offers "1, 3, 7, 14".
Love ideas like this that make me think "How hadn't someone thought of this yet?" Interested to see how big the market ends up being.
What's the size of the flight insurance mkt.? That could give some indication.
Great idea. Question about the 1-day $6 charge -- Isn't there a 24 hour free cancellation window for all US booked flights (I thought I read it was a rule somewhere).
