Many commercial transatlantic flights between the United States and Europe resumed today, three days after air links were shut down by terrorist attacks against New York and Washington.
But all Aer Lingus transatlantic flights remain cancelled today.
An American Airlines flight from Chicago touched down at 8 a.m. Irish time at London's Heathrow airport, the company said.
It was the first passenger flight to land in Europe from the United States since Tuesday's devastating strikes.
Another American Airlines plane left Heathrow bound for Chicago just after 11 a.m. after the observance of an EU-wide three minutes of silence in honour of the victims.
The company has said it hopes to have a limited number of services leaving from Heathrow and Gatwick, south of London, during the day.
Another of the airline's planes could take off from Paris later in the day, subject to US federal aviation authority approval, a spokesman added.
Flights by European carriers to the United States remain grounded pending a safety ruling by the US Federal Aviation Administration.
Meanwhile, London's smaller City airport reopened Friday. It had been shut since Tuesday.
Emergency restrictions barring planes from overflying central London before landing are to be lifted from midnight tomorrow.
British Airways said it would resume some services from Britain to Canada, but BA flights to Islamabad in Pakistan - bordering Afghanistan where the chief suspect for the attacks, Osama Bin Laden, is based - remain suspended.
Virgin Atlantic, another main British transatlantic carrier, said it would operate a flight to Toronto but not the United States.
