Flights will begin at 4 p.m. EDT, and Spirit expects to resume full service on Friday.
Spirit pilots had been negotiating for more than three years before the strike started Saturday morning. The union said first officers in particular lagged their counterparts at other low-cost airlines like JetBlue Airways Corp. and AirTran Airways.
Chicago Tribune (AP) | Low-cost airline easyJet PLC unveiled plans Friday to test infrared technology's ability to detect volcanic ash clouds and urged other airlines to help map the ash risk across Europe's skies.
The company said the devices—which are placed on an aircraft's tail fin and can detect ash clouds within 60 miles (100 kilometers)—are the first of their kind, calling them "essentially a weather radar for ash."
The airline is spending 1 million pounds ($1.46 million) developing and testing the technology with aircraft manufacturer Airbus and hopes to roll out the devices in a dozen planes by the end of the year. The devices aim to prevent a repeat of the five-day shutdown of European airspace in April caused by an erupting Icelandic volcano that affected 10 million passengers worldwide.
