The operator, Airports of Thailand, say they have shut down the Suvarnabhumi airport indefinitely.
A spokesman said:"We have already informed the airlines who operate from it.
"Flights in the air will be diverted to either Chiang Mai, Phucket or other airports, but it closed as of 9pm (2pm GMT)."
British Airways told Sky News that one flight to Bangkok had already been canelled and another flight had been diverted to Singapore.
A BA spokesman said the decision was regrettable, but the deteriorating situation in Thailand had left them with little choice.
At least 2,000 supporters of the People's Alliance for Democracy (PAD) had surrounded the airport as part of their six-month campaign to oust the government.
Police Colonel Theeradej Chanurak, a senior police official responsible for the airport, confirmed that protesters then entered the terminal.
He said: "Some of the protesters have entered the terminal buildings.
"They walked towards it while police tried to stop them but could not do anything as police have received orders not to use any force."
