Are Scotland's airports for or against Heathrow's expansion?

Scotland has 15 airports - six main centres and a further nine dotted around the Highlands. All but one is in favour of a third runway at Heathrow Airport.

For Heathrow expansion

• Glasgow International - Owned by a consortium formed by two companies - Spanish firm Ferrovial and Australia-based Macquarie

• Glasgow Prestwick - Scottish minister became owners of the Ayrshire facility after the Holyrood government bought it for £1 from owners Infratil in late 2013

• Aberdeen - Owned by a consortium formed by two companies - Spanish firm Ferrovial and Australia-based Macquarie

• Inverness- Highland and Islands Airports Limited (HIAL), which runs the airport, is a public corporation wholly owned by the Scottish ministers

• Dundee - Part of the HIAL group

• Barra - Part of the HIAL group

• Benbecula - Part of the HIAL group

• Campbeltown - Part of the HIAL group

• Islay - Part of the HIAL group

• Kirkwall - Part of the HIAL group

• Stornoway - Part of the HIAL group

• Sumburgh - Part of the HIAL group

• Tiree - Part of the HIAL group

• Wick - Part of the HIAL group

Ahead of the UK government's decision on airport expansion, the managing directors of Aberdeen and Glasgow said they would back the Heathrow plan because it was the "right choice for the whole of the UK".

The Scottish government also backed a third runway for Heathrow, saying it could lead to a 16,000 jobs boost. At the beginning of this month ministers signed a Memorandum of Understanding with Heathrow Airport bosses.

Against Heathrow expansion

• Edinburgh - Owned by Global Infrastructure Partners (GIP) which also owns Gatwick Airport.

Ahead of the Heathrow decision, the Edinburgh Airport operators said they believed Gatwick "offered the better deal for Scotland" and described the Heathrow plan as "undeliverable" and potentially "bad for passengers".
