The Welsh Assembly Government wants daily transatlantic flights from Cardiff International Airport to America. Economic Development Minister Andrew Davies said he had looked at the possibility of flights to the Middle East and regular flights to Brussels.
But he said offering more flights was a commercial decision.
He also raised the possibility of diverting mainline trains from Paddington to the Vale of Glamorgan to improve access to the airport in Rhoose.
"One of the things I have been looking at is getting trains from London Paddington to go from the Vale of Glamorgan line," said Mr Davies.
