According to a report from the Las Vegas Review-Journal, Allegiant Travel Co., the parent company for Allegiant Air, were among a handful of folks who signed the steel beam as it went up. The beam itself is one of 26 roof trusses, and marks the "topping out" point for the stadium, marking the highest point of it. After months of rumors, Allegiant confirmed the official name, and although terms weren't disclosed, reports estimate the deal to be somewhere around $20-25 million.
