Jet-fuel crunch could derail this summer’s travel plans

A looming jet-fuel shortage tied to the Iran conflict could push prices higher and force airlines to cut capacity, threatening summer travel especially for international trips and European routes; Europe may have only about six weeks of jet fuel left, while the U.S. is better insulated but could still face higher costs. Travelers should know airline rights, document transactions, keep contact info up to date, act quickly on changes, consider nonstop itineraries, and weigh travel-insurance options to mitigate disruption.
