More than half of UK airports STILL don't have free water fountains

Last year we revealed how to find free water at airports which do have fountains installed, so that passengers can fill up empty bottles and avoid rip-off prices after security. We also wrote to the chief executives of the 18 UK international airports which didn't have fountains urging them to install some.

Almost a year on Exeter Airport has now installed a free water dispenser, while Aberdeen, George Best Belfast City and London City airports have all confirmed they will be installing free fountains. Glasgow Prestwick and Liverpool John Lennon told us they are considering following suit.

The remaining airports say passengers can ask for free tap water at restaurants and cafes - though this is less convenient and could be off-putting, particularly if you're not buying anything.

How to find free water at airports

Although passengers aren't allowed to take liquids of more than 100ml through security at airports, the Civil Aviation Authority has confirmed you ARE allowed to take empty water bottles through to be filled airside - meaning you can fill them up on the other side and so avoid buying pricey bottled water for your flight.

We've compiled a list of exactly where you can find the free water fountains or dispensers at the following 13 UK airports in our Overseas Travel Tips guide:

• Birmingham

• Bristol

• East Midlands

• Edinburgh

• Exeter

• Gatwick

• Glasgow International

• Heathrow

• Jersey

• London Stansted

• Luton

• Manchester

• Southampton

Which airports DON'T offer free water?

Here's a list of the 15 airports which told us they don't have any water fountains:
