Aer Lingus says they are not expecting significant disruption to flights to the US in the wake of the plane crash in New York.
Flight 105 due at JFK at the time of writing is expected to land on time with the return flight in the early hours of the morning expected to run close to schedule.
The company say they are not anticipating serious disruption but warn of the possibility of delays. They advise intending passengers to present themselves at Dublin and Shannon airports at their scheduled times.
British Airways said it had diverted one flight scheduled to land at JFK to Boston and had called one plane back to Heathrow. It still has two aircraft due in New York around now.
"We are holding all other flights from Britain to New York at the moment waiting for approval for when it might reopen," a spokesman for British Airways said.
"We are still gathering information and we don't know the level of disruption. Passengers en route to North America are advised to contact their airline before setting out for the airport," the spokeswoman added.
Air France, which joined BA last week in resuming supersonic Concorde service to New York, said it had suspended one flight and was rerouting four others.
Swissair said its flights to Kennedy from Zurich and Geneva were on their way. It said Flight SR138 from Geneva is expected to arrive.
In Budapest, the domestic news agency MTI said that Hungarian airline Malev had turned back a flight to New York.
Dutch airline KLM said delayed flight 641 from Amsterdam to Kennedy was expected to depart later this evening.
But an earlier flight from Amsterdam to Newark, which departed before the crash, was expected to land as scheduled since the closure was only temporary, spokesman Mr Huge Baas said.
