Luggage limitations might be a minefield, but so too is the packing process. Many travellers struggle to travel light and adhere to stringent hand luggage restrictions, particularly when travelling on budget airlines for a weekend away. Meanwhile, a large baggage weight limit can prove equally problematic – sometimes prompting holidaymakers to go all out and cram in a host of items they may not need, simply because they can. Yet for frequent flyers, who travel often and sometimes at short notice, a series of “lifesaver” items prove key.

The style guru, who has 16 years experience at the top of the industry, insisted to comfort did not mean a compromise.

She said: “I would suggest when it comes to flying, to look chic yet comfortable is key.

“A large scarf or shawl is excellent to help you stay warm, keeping the air conditioning on the planes at bay.

“I love changing into a sweatshirt and popping on an eye mask.

“They really help deepen your sleep if you’re travelling at night.

“Thick socks are also a great option to wear mid flight instead of your shoes.

“Plus they make you feel super cosy.”

Alex added: “I advise changing back into your airport travel outfit an hour before your plane lands and that way you will feel more refreshed, and not in the same clothes for an extended period of time.”
