Brands like Derek Rose, Sunspel and Loro Piana are key here but come with hefty price tags of between £500 (considered mid-priced) and £2,000. A quality cashmere-cotton blend, offered by the likes of J.Crew, is a more affordable alternative that doesn’t compromise on style.

Highly Recommended

In addition to the above essentials, the following three items come highly commended for their ability to turn air travel from an obstacle course to a walk in the park.

A Portable Charger

For all it’s wonders, today’s modern technology appears to lose life quicker than ever. Popping a portable charger in your carry-on will allow you to top up your juice so you can watch that pre-downloaded boxset without the risk of running flat.

Knomo Power Pack For Smartphones, available at knomobags.com, priced £89.

Water Filter Bottle

Keep skin hydrated from within when flying by drinking plenty of water. While it’s worth checking with the airport/airline beforehand, many allow empty water bottles over 100ml to be taken through security.

Investing in a refillable bottle with its own filter system will stop you having to shell out £3 in a last minute dash to WHSmith.

Brita 600ml Fill & Go Water Filter Bottle, available at George At Asda, priced £14.

Inflatable Travel Pillow

Despite budget airline’s ongoing efforts to make their seats increasingly comfortable (note: sarcasm), many wake with a crick in their neck after an on-board nap.

A supportive neck pillow is the best way to avoid this but can take up precious room in your bag. So opt for an inflatable version that can be quickly stowed away for your onward journey.
