Perhaps not surprisingly, a survey of nearly 10,000 travellers by Expedia and Egencia, the number one must have when travelling is the mobile phone. Over half of travellers check their work emails on their mobile phone at least daily while on holiday, while 60 per cent would not consider going on holiday without a mobile device.

It is now deemed more important to ‘professional travellers’ than deodorant, a driver’s licence and even a toothbrush.

Mobile devices may be a requirement for business trips, however, Rob Greyber, President of Egencia says business travel and connectivity is changing. “Various devices allow for a seamless experience with apps that enable users to be more productive and efficient, which travellers are utilising in order to prioritise work-life balance and disconnect when possible.”

Aman Bhutani, President for Brand Expedia Group, adds, “We have found that travellers are using mobile devices at every stage of the travel process, from researching and booking trips to capturing and sharing the travel experience.” He also said: “And just because a traveller can use their device to read work emails and stay connected to the office, they also believe it improves the quality of their vacations.”
