Frontier Airlines EarlyReturns (Pre-Alignment) - Promo code to join Early Returns?

Hi all,

I've never flown "the animal", but I was considering joining Early Returns and playing some games at Live Search to buy some miles for them (I like playing games, but Live Search doesn't support any of the airlines that I usually fly). In the worst case I won't use the miles and will just end up giving F9 a miniscule amount of support; If I play enough to get a ticket on AirTran so much the better. On their sign up page for Early Returns they ask if you have a promotional code - are these given out often (i.e. should I wait to join) or is this such a rare event that it's not worth waiting?

I hate to post a "me too," but I'm curious about this as well. I just booked a SEA-LGA itinerary for July on F9. If by some miracle they're still flying by then, I'd like to collect the miles. I don't see myself flying F9 much though; they're not a very strong presence here in SEA.

A search among the coupon sites shows nothing now. Might be something to watch for when they come out of BK. A sign-up bonus could help bring new blood into EarlyReturns.
