Unesco is adding to its list of World Heritage sites, the TSA defends its adult diaper screening, Australian airlines resume flying after a five-day shutdown, Hilton is coming to Mombasa's North Coast, and more. Here is what travellers are buzzing about:

World's newest cultural and natural wonders
In Paris, the United Nations committee that manages the list of World Heritage sites is set to add more places to its list between now and Wednesday. Last week, UN Educational, Scientific and Cultural Organisation (Unesco) added eight World Heritage sites to its register of 923 cultural and natural sites. New man made treasures include the historic district of Bridgetown, Barbados, and the Walter Gropius-designed, steel-and-glass Fagus Factory in Germany. New natural wonders include Japan's Ogasawara Islands, which lie about 600 miles south of Tokyo and are nicknamed the "Galapagos of the Orient" for their unique wildlife, reports Yomiuri Shimbun. The committee is considering 29 other nominations. 

TSA defends its adult diaper screening
The Transportation Safety Administration (TSA) says it was right to make a 95-year old woman in late stages of leukaemia remove her adult diaper for a security screening, according to an agency statement reported by the New York Daily News. "If this is your procedure — which I do understand — I also feel that your procedure needs to be changed," said Jean Weber, the woman's daughter, to CNN. "It's something I couldn't imagine happening on American soil."

Australian airlines resume flights to New Zealand
This morning Qantas, Jetstar, and V Australia resumed most flights between Australia and New Zealand after a five-day disruption due to a volcanic ash plume from Chile, reports Bloomberg. For details, see each airline's website.

No word yet on the possible Virgin Atlantic strike
As we reported last Thursday, pilots for Virgin Atlantic have voted to strike, but no dates or times have yet been announced. Travellers planning to fly the airline this summer should make sure Virgin has the most up-to-date contact information in the event a strike disrupts their plans.

Hilton may open a hotel in Mombasa, Kenya
The East African nation of Kenya scared away travellers in 2008 after election-related violence, but visitor numbers have since recovered. In a promising sign, the Hilton hotel chain plans to build two properties among the beaches and game reserves of Mombasa's North Coast, according to an interview with the country's tourism minister reported by The Standard. We can only hope that Mombasa will be one of the sites for the new sub-brand of hotel and beach clubs being created by Paris Hilton, the 30-year old heiress to the chain, according to Parade last week.
