Declining passengers make for uncertain future for Portland Jetport.

Portland International Jetport is one of dozens of airports across the country that could see a sharp drop in service if high fuel costs trigger a potential “catastrophe” in the airline industry, a business travel advocacy group says.

The Business Travel Coalition issued a report this week that said rising aviation fuel prices threaten to put some airlines out of business, force others into mergers and lead almost all airlines to continue dropping less profitable routes, put older airplanes out of service and cancel orders for new jets. That could lead to sharply diminished service at roughly 60 percent of the country’s 250 major and regional airports, the group said.
