Airline ticket promos Downtown still a thing?

Do any Downtown casinos still offer up goodies for bringing your boarding pass in within 24 hours of arrival?  Is it only specific airlines? 

 Both the "D" and El Cortez have boarding pass offers. If you call them , they will spell out the specifics of their offers. The reason I suggest calling each of them is that they sometimes "tweak" their offer. They are both worth the time and effort to check out and take advantage of.

and golden gate

 I just called the Golden Gate and they also have the boarding pass promotion, which I was unaware of. If you show a Southwest, Alligent or Spirit boarding pass within 24 hours of arrival in Vegas they will give to you a $50 matchplay chip. I believe that this is the same for the "D".

Thanks for the quick replies!  We arrive Monday on Southwest Airlines so we'll check them all out.

 I believe that @ the El Cortez you have either 3 or 7 days after arrival to take advantage of this perk. 

i've done the D and golden gate on different trips, but never tried both. would be interested if they would allow that

These are only once per year, right?

don't think so. el co only once per year, but others each trip.

I have done the allegiant airlines offer at the GG everytime and that is 5 or 6 times a year. No problem ever!
