Since fares can expire/disappear at anytime - do the experts still get to keep their commission if its gone by the time the contest creator decides to book it? Do experts have time caveats around their entries?
Edit: Grammar
As you can imagine, this is a fairly big challenge for us. As we grow it will become less important because experts in your timezone will tend to reply, but now, we simply implore customers to book quickly. We haven't had too many issues because a lot of the value comes from not-so-temporal factors.
Aside from that, we offer a full refund to anyone that asks for any reason.
