The new screening measure is being introduced to meet new security requirements from the US for all passengers travelling to the US on all international airlines.
It is believed some passengers will be handed a form to fill out, while others face being quizzed by airline employees.
Global long-haul airlines such as Emirates, Lufthansa, Cathay Pacific, Virgin Atlantic and Eyptair had already announced their new measures.
In March, the US banned passengers from taking large electrical devices such as laptops on board flights from eight mainly Muslim countries over security fears.
A similar policy was introduced by the UK, although it affected some different locations.
Virgin Atlantic said in a statement: “We work closely with US authorities to ensure the safety and security of our flights, and are aware of the additional measures - however we do not anticipate any disruption to customers.
“We advise all customers travelling on our flights to arrive at the airport at least two hours before departure.”
