What happened to the passengers at Heathrow Airport on Sunday?

Chaos segued into fatigue and frustration at Heathrow Airport on Saturday as thousands of exhausted, exasperated British Airways passengers left stranded by an unofficial strike desperately searched for news--any news--about when they might get out of Britain. British Airways, facing a public relations disaster as well as losses that could reach tens of millions of dollars, said about 80 percent of flights were running as planned. The strike began when the catering firm abruptly fired about 670 of its Heathrow-based workers on Wednesday, causing the rest of the catering staff to walk out in a show of support. On Thursday, about 1,000 other airport workers--including baggage handlers, bus drivers, ramp workers and check-in staff, walked out, too, for an unofficial strike.
