A travel expert has warned people to look out for one symbol when they're booking their flights
Google Flights is a great way to compare prices and travel times, particularly when booking a long haul flight, but there's a certain symbol you should be wary of.
As many frequent travelers know, most long haul trips include a connecting flight to your location as it's too far to travel in one sitting.
Most people don't want a ridiculously long waiting time between their flights because, you know, there's only so much money you can spend in Dunkin' Donuts.

Sometimes the waiting time on a connecting flight can be an overnight layover - something which travelers might not realize when booking their journey.
Highlighting this, travel fanatic and TikToker Travel Deals by Dan, who goes by @tripdealsdan on the video sharing platform, said to keep an eye out for an exclamation mark inside a triangle symbol on the flight information.
He explained: "It's very important if you do see this symbol, it's important to pay attention to what it's trying to warn you about."
"It's very important to consider because you wouldn't want to be in the [airport] that long," Dan went on.
One of the four reasons highlighted by Dan was that if there's an overnight layover, it's likely you'll need to book a hotel at your own cost between your flights.
He also noted that if you leave the airport in this timeframe, you're no longer a transit passenger but you're properly entering the country and may need a visa.
"That's something to be wary of," the TikToker said.
Another point Dan brought to people's attention is that the symbol might also mean your connecting flight is at a different airport, therefore you'd need to make your own way there.
"You're going to have to [do the transfer] on your own, most likely," said Dan. "Sometimes airlines don't have a free shuttle or what not."
He further warned: "You may need a visa for that transit as you are no longer in the airport."
The fourth and final reason for the symbol explained by Dan was that your differing flights might be different cabins; for example, your flight from London to New York could be business class, but the connecting flight from New York to Nashville is economy.
"It's so important to note that you're not getting the same class all the way through," he said.
"Be wary of that before you jump to buy tickets that may seem too good to be true."
"This can happen on any airline across all classes," Dan went on.
