It’s a well-known fact that once you’ve passed airport security, there’s no turning back – and this often means having to accept inflated prices for necessities.

The cost of food is typically higher than usual, but it’s a small price to pay to keep the holiday excitement alive. However, one savvy traveller insists that there are certain areas where you can avoid these steep mark-ups, as she revealed a trick to dodge the “overpriced” items while eagerly awaiting your flight to your dream destination.

TikToker @hangrybynature shared her “three life-changing tips for flying,” one of which many travellers may not have even thought about.

She suggests bringing a reusable water bottle through security, explaining that “once you pass security checks, you’ll find water fountains everywhere to fill your bottle.”

This simple tip could “save you from buying overpriced airport water,” where the cost of staying hydrated can be significantly higher. And let’s not forget, purchasing water on the plane itself can also be quite costly.

She also shared other useful hacks such as “finding the latch” to allow you to “slide in and out” of your plane seat “with ease,” eliminating the struggle of getting in and out – particularly if you’re seated in the aisle.

She revealed that the latch is “beneath the aisle seat handlebar,” and by lifting the armrest, you can avoid accidental bumps and bruises when hastily getting in and out of the seat – a situation all too familiar when someone is behind you, the trolley is coming down the aisle, and speed is of the essence.

Her final piece of advice was to avoid exchanging currency at the airport, as she explained: “Because they know tourists are scrambling for local currency when they arrive, and you never get a good rate.”

She even suggested that withdrawing money from an ATM might be a better option than using an airport exchange service.

Another travel expert commented on her tips, saying: “Great tips, and sometimes I take what we know for granted.”

One individual expressed frustration at themselves for not being aware of the “about the armrest” hack, with another vowing they’d “definitely” try it on their next flight.
