The Ted Stevens Anchorage International Airport is again picking up plans for a hotel on airport property, and already four developers are interested.

Two locations have been proposed for the potential hotel, said airport leasing and concessions business manager Tom Hubble. One is between the airport's South Terminal and North Terminal, where the hotel would be connected to an already-existing walkway so guests could travel directly to gates without going outside. The other is between a rental car facility and the train depot at the airport, where Hubble said any hotel would also be connected to the airport "in some fashion."

The project could cost between $40 million and $60 million, based on the applications the airport has already received, Hubble said. The airport is reviewing those applications and expects to put the project up for a bid "sometime this year."

"The goal is to have something awarded and ready to begin construction in 2018," Hubble said. It would be a privately funded project, he said.

Right now, there are hotels nearby, but none actually on airport property.

Hopes for an airport hotel have come up before in Anchorage. In 2014, Alaska Dispatch reported, one was planned at the North Terminal. At that time, construction was expected to begin "as early as 2015," according to the Alaska Dispatch article.

That project didn't move forward, Hubble said, because of a change in leasing management between 2014 and 2015, and because airport concession projects took priority.

Those projects included Pork & Pickle, Sushi on the Fly and Sleeping Lady Airport Lounge.

"All those restaurants are now open and operational," Hubble said. "We're trying to move forward with the hotel now."

Two Alaska companies — Mageik Glacier LLC and Anchorage HH Holding LLC — have already submitted applications for the hotel project. (Anchorage HH Holding notes on its application that the company is "to be formed." The company's name doesn't come up on a search of Alaska business licenses and corporations.)

PEG Development LLC in Utah and A&A Construction and Development Inc. in Washington state have also applied. PEG's proposal is for a Delta Hotel (a Marriott brand), while A&A Construction and Anchorage HH have both proposed Hilton hotels, Hubble said. Mageik didn't mention a specific brand in its application, he said.

None of the companies returned phone calls Tuesday seeking comment about their potential development plans.

Hubble said the hotel might specifically appeal to tourists, people who have layovers flying in and out of Bush Alaska, people with early departure times and those traveling for work.

"I think it's just proximity and convenience," he said. "We've been looking at it at the airport for quite some time."
