LONDON - The snow was melting off the streets, but Heathrow Airport told infuriated passengers it won't restore full service until Thursday, five days after a five-inch snowfall turned holiday plans into a nightmare of canceled flights and painful nights sleeping on terminal floors.

Travelers' anger boiled over into politics as Prime Minister David Cameron offered to put troops on snow-clearing duty and Europe's top transport official threatened tougher regulation of airports unable to cope with wintry weather.

Problems persisted in Germany, where Frankfurt airport, continental Europe's second-largest hub, saw 550 cancellations out of a total of about 1,300 flights Tuesday. - AP
