BOISE - The countdown is under way as Tuesday marked just 11 days until the Boise State Broncos take on the Oregon Ducks in Las Vegas for this year’s Las Vegas Bowl.

While travel experts say the demand for the December 16 game isn’t as large as, say, the Fiesta Bowl, getting down to Las Vegas this time of year is tough with only a select number of non-stop flights to Las Vegas.

Allegiant and Southwest Airlines are the only two airlines that have non-stop flights to Las Vegas from Boise, and those fly-out Friday and return Sunday flights are going fast.

“It's a busy time of year to find inventory on the airlines,” Evelyn Loveless with Global Travel said.

While that’s good for the airlines; it’s not so good if you’re trying to travel down to Las Vegas next week for the Las Vegas Bowl.

Many of those non-stop flights already showing “sold out.”

“The inventory is really low,” Loveless said.

Loveless is setting up customized trips down to Las Vegas for the bowl game and is suggesting to her travelers to leave earlier and come back later.

“Fewer seats available commercially on Friday and Sunday, but if you could go Thursday and come back Monday we can get low prices still,” Loveless said.

Bob Harmon with Harmon Travel offered a charter flight down to Vegas, which he says all 165 seats sold out on Monday. Harmon Travel has started a wait list, which has about 20 people, but Harmon doesn't anticipate it to grow much more.

“It's pretty much run its course,” Harmon said.

Travel experts believe timing, with the game being played right before Christmas, and the quick turnaround from when the bowl game was announced could be playing into demand.

“The momentum has been pretty brisk,” Harmon said. “Comparing it to the prior two Las Vegas Bowls, less than the first one, more than the second one."

One of the driving forces behind some of the demand, Harmon says, could be who Boise State is playing against.

“There was a little bit of nervousness that the opponent might not be that high of a caliber, but I think the Oregon Ducks are considered to be a very fine opponent,” Harmon said.

Las Vegas Bowl staff tell KTVB Boise State received 11,000 tickets for this year’s game. Boise State couldn’t provide the number of how many of those tickets are left.
