How being a Twitter-savvy expat can save a fortune Customers who mention the passwords at any of its hotel check-ins qualify for perks such as free room upgrades and breakfasts. While a useful money-saving tool, social media sites can save time too. Facebook and Twitter are often used by airlines to announce delays and disruptions, preventing passengers from wasting valuable hours at airports. Janine Clements is a British expat living in Singapore and is a serial tweeter with her handle @mummytweets. She said: "I follow a lot of local airlines as they often announce free flights or big discounts, but I also follow the major airlines such as British Airways and Singapore Airlines. They might do deals back to the UK. Through Twitter I have met many other expats and recently I meet up with a group I met on Twitter in Singapore. I also met up with visitors from the UK over here that I made contact with via Twitter. The mother-of-two added: ""Twitter is also very useful for helping you find your feet when you first arrive in a new country. I still often use it to get recommendations on where to go and what to do, places to eat and to find out things to do with kids."" Government organisations are also turning to social media to keep in touch with British expats across the globe. The Foreign and Commonwealth Office (FCO) tweets news and announcements to its 44,000 followers around the world via @FCOTravel. The Twitter feed also allows travellers and expats to post non-urgent questions and receive answers from FCO staff. Around 125 of the FCO's overseas posts have their own Facebook pages, and more than 100 have Twitter accounts that are used to communicate changes to travel advice.
