Boarding Pass deals

Just got back from another vegas trip. On the flight in on Allegiant air I came across some free play deals with your boarding pass. Ended up getting $25 slot play when you play $50 at a downtown Boyd casino. Ended up using it at the Fremont. Then got $10 from El Cortez in slot play and $10 in match play. I was not able to make it downtown to use the $50 match play at the Golden Gate in time(had to be within 24 hours). I'm not sure if I'll be able to do this on my other trips this year or not or if it a once a year time deal. Is anyone aware of any other airline deals like these? Southwest Airlines?

You missed the Downtown Grand Allegiant deal. The Grand gives repeat users a free T shirt and a $10 table game matchplay. The Grand also gives repeat users a BOGO for their in the casino over priced restaurant. I believe they give more for new sign ups. I don't know how quick after landing you have to redeem their boarding pass. I do know the Allegiant deal has other restrictions that I have run into. The Boyd properties play $50 get $25 free is only good once a calendar month. The El Cortez deal is good once a year unless a certain amount of base slot points are earned between boarding pass visits. I think that figure may be 1500 base points but I'm not sure. Just trying to give feedback. Others may have more precise information. I am not aware of other airlines boarding passes being honored. If any LVA member knows of another airline boarding pass deal please do tell!
