Inside Tuvalu: This tiny island nation has just one airline, almost no tourists, and a future threatened by rising seas

• Tuvalu is one of the least visited countries on earth.
• A single airline, Fiji Airways, operates the only scheduled flights in and out, connecting the capital atoll of Funafuti to Fiji a few times a week, and there is no other way to reach the country by air.
• The entire nation is made up of nine coral atolls covering roughly 26 square kilometres, smaller than many major airports, and is home to just under 11,000 people.
