Colin Matthews, chief executive of Heathrow; Stewart Wingate, chief executive of Gatwick; Glyn Jones, managing director of Luton and Nick Barton, managing director of Stansted are due to be questioned this afternoon.
Campaigners opposed to airport expansion are also due to appear. Tim Johnson, director of Aviation Environment Federation and Chris Crean from Friends of the Earth are two of the organisations who'll face MPs questions.
