IF you're flying overseas, it's likely a layover is also on the itinerary.
But even short layovers can eat into your holiday's spending money, depending on which airport you're passing through.
Comparison site Mozo.com.au looked at 15 major airports and assessed the price of water, coffee, a sandwich, beer, toiletries and a stay at an airport hotel.
It found international airports in Los Angeles, Paris and New York were the most expensive while airports in Seoul, Bangkok and Johannesburg had the lowest prices.
"Mozo found a 175 per cent price difference between airport layover pricing, indicating that some terminals are well and truly more affordable than others," said the site's director Kirsty Lamont.
"The highest cost was airport accommodation, with a night's sleep setting you back $AUD206 in Los Angeles compared to $AUD64 in South Korea."
A simple sandwich varied from $2.87 (Bangkok) to $15.57 (Heathrow) while a bottle of water could cost as little as 62 cents (Bangkok), to a whopping $5.15 (LA). Beer ranged in price from $2.26 (Bangkok) to $12.65 (Dubai).
Ms Lamont said there were a few handy tricks that could save you hundreds of dollars.
"Investing in a high-quality neck pillow can replace an expensive stay in an airport hotel and packing a reusable water bottle and snacks can help avoid paying exorbitant prices for food and drink. That way you can put more of your money towards truly enjoyable holiday experiences."
