A Delta Air Lines flight bound for the United States makes an emergency landing at Porto Airport in northern Portugal after smoke is reported in the cabin. Local civil protection authorities say the aircraft diverts and lands safely.

Multiple outlets report that the jet is on a route from Barcelona to Boston, with 296 people onboard. After landing, passengers receive assistance on-site. The civil protection service states that 14 passengers need medical attention following the incident, and four of them are taken to hospital for smoke-related symptoms. Media accounts also describe that passengers use emergency procedures during the evacuation.

Coverage focuses on the immediate response and passenger care, with details centering on the smoke detection, the diversion to Porto, and the number of people treated. The reports do not indicate broader causes beyond the cabin smoke alert, and they present the same overall timeline: smoke is detected, the flight diverts, and the plane lands without reported loss of control or injuries beyond treatment for smoke exposure.
