DENVER ” The Colorado Rockies may be more than just a mile high if they land in the World Series.

Denver-based Frontier Airlines is negotiating with DirecTV satellite television service for permission to show the World Series on its flights if the Rockies are participants.

The Colorado team hoped to clinch the National League pennant Monday night with a victory over the Arizona Diamondbacks to take the best-of-seven series 4-0.

Although it already offers satellite TV service on its flights, Frontier does not carry the Fox Network where the World Series will air, Frontier spokesman Joe Hodas said Monday. It also needs to make sure it has the rights to air live television.

“We are trying very hard to get that squared away,” he said.

Hodas does not believe there will be additional costs involved because it would be a one-time promotion for Frontier.

It isn’t the first time the carrier has made such arrangements ” it also shows the Super Bowl on its flights every year.

Frontier offers flights to 59 destinations in 30 states, Mexico and Canada.
