U. S. Customs and Border Protection has denied a proposal to fly tourists between Fairbanks and Canada's Dawson City.

The Fairbanks Daily News-Miner says customs officials are unwilling to relocate workers to Alaska's interior to meet those flights.

Holland America wanted to begin the flights next summer, using Whitehorse-based Air North to shuttle as many as 19,000 people between the two destinations.

But in a letter to Air North, Customs' Anchorage area port director Lance Robinson said relocating workers to Fairbanks would be "an inefficient use of our existing resources."

U.S. Sen. Lisa Murkowski's office says the Alaska Republican plans to formally support an appeal filed by Air North.

Holland America spokesman Erik Elvejord says the company is still hoping for a resolution to allow the flights.
