Found this when booking next Vegas stay. Got great rate and a few perks, but the one that intrigues me the most is the Fly Back Free Airline Certificates.

When I call reservation number 877-632-7800, I am only told that these certificates are presented at check in and allow for free travel back to Las Vegas for future stay. Seems like a great promo but could not get the restrictions involved, i.e. how to book, pay fees or taxes, limited carriers, will I get miles, etc. Then called another number 866-459-7770 but found it to be a division of Archer Travel, maybe a travel agency that books these tickets for Mandalay Bay? Unfortunately they are closed over the weekend.

More information about reservation promotion found here: https://reservations.mgmmirage.com/b...&sub=vhs1208mb

So lastly my question, has anyone successfully booked these trips or gotten the free airline certificate before? My stay is coming up next month and I would like to know if these certificates are worthwhile or not.
