Winter storms disrupt Logan-to-London flights

Even those travelers who did get out of Boston over the weekend found it to be rough going. A British Airways flight that took off Saturday morning was diverted to Newcastle, England, and passengers had to be bused nearly 300 miles into London.

Delays and cancellations at Heathrow will endure at least through tomorrow, and more heavy snow is expected to fall in London later in the week. “It’s sort of day by day,’’ said John Lampl, spokesman for British Airways.

Flights out of Logan have not been disrupted by weather in other major European cities, including Paris, Frankfurt, and Amsterdam, said a spokesman for the Massachusetts Port Authority, which operates the airport.

Logan officials also said they aren’t anticipating any disruptions related to the controversial full body scanners and enhanced pat-downs that the Transportation Security Administration put into place this year. An informally organized national “opt-out’’ protest the day before Thanksgiving — in which travelers were urged to ask for a more time-consuming pat-down instead of a scan to draw attention to the more invasive security measures — did not produce any major delays in Boston or elsewhere.

The busiest Christmas week travel days at Logan are anticipated to be today and Thursday, with more than 100,000 passengers expected to pass through the airport on each of those days. Planes are full, officials said, but the crush won’t be quite as severe as it was during Thanksgiving week. That is, of course, if the weather in Massachusetts cooperates — current extended forecasts call for the possibility of snow late Christmas night and Sunday.
