Anyone getting this plane ticket risks red flag at the airport

It is common for a lot of travellers to book one way flights when jetting off abroad. For those embarking on an open-ended holiday or gap year, there really is no other option.

However, some destinations require you to have proof of onward travel, and inability to provide this could lead to questioning at immigration or even refusal of entry.

This does not happen to every traveller, but when it does, it can be a nightmare that can hugely disrupt your plans.

An expert at Experience Travel Group explains the potential consequences. "A one-way ticket is not illegal, but without onward travel documentation, you may be selected for additional checks.

"Immigration officers assess the likelihood of overstays, and a one-way ticket can raise concerns."

The rules on this are not entirely universal, and it is usually at the immigration officer's discretion whether to undergo security checks and potentially take further action.

Despite this, there are countries more prone to requiring proof of onward travel, including Thailand, Indonesia and New Zealand. It has also been known to happen in the United States.

There are a variety of consequences that could arise as a result of buying a one-way airline ticket, including the incident being logged on immigration databases.

A British traveller who was headed for Thailand reportedly had to buy a last-minute ticket to a neighbouring country, which set them back a hefty sum as it was purchased so close to departure.

In the most serious cases, you may get your visa cancelled, lose your prepaid bookings and immediately be sent back on the next flight home - which you will have to pay for.

Experience Travel Group offers several solutions to the issue, just in case you find yourself in a stressful position where you could end up spending more money than you need to.

Book a flexible return ticket - many airlines offer refundable or changeable tickets that provide both proof and flexibility

Purchase a low-cost onward ticket - it may be worth searching round for the cheapest possible nearby flight, which can satisfy the requirement even if it is not used

Research entry requirements in advance - rules and requirements are different everywhere you travel to

Carry printed proof - a paper copy may speed up the checking process

Despite offering valuable flexibility, a one-way ticket might bring about more problems than it is worth.

"Proof of onward travel is straightforward to arrange and can prevent significant disruption", a spokesperson from the company said.

"Even if you are not asked for it, having it ready is a sensible precaution".
