Gas prices are climbing in Honolulu and across the country, bad news for drivers and anyone who depends on cheap travel.

• Honolulu gas jumped 15 cents a gallon in a week, now over $5.40, and prices are up in nearly every state, some by more than 30 cents.
• The main cause is the U.S. conflict with Iran, which has cut oil supply and pushed prices higher everywhere, not just in Hawaii.
• Drivers are cutting back: switching from cars to mopeds, walking and biking more, and skipping weekend trips.
• Gas station owners say they make little profit on gas itself and earn most of their money from in-store sales and services.

Outlook: Where prices go next depends almost entirely on what happens between the U.S. and Iran, with no relief in sight for now.
