The Star Alliance group of airlines has expanded its Asia Airpass to include Nepal, Bangladesh, Pakistan and Sri Lanka.
The pass will now cover over 235 destinations in countries ranging from China and the Philippines to Indonesia, Cambodia and Mongolia, Star Alliance said.
Passengers can use the pass to take between three and 10 flights with carriers including Asiana, Air China, Lufthansa, ANA, Singapore Airlines and United Airlines.
Fares are calculated based on the flights chosen and offer better value than buying individual airline tickets, according to Star Alliance that is a network of leading global airlines, with the highest number of member airlines, daily flights, destinations and countries flown to.
Established in 1997 as the first truly global airline alliance to offer customers convenient worldwide reach and a smoother travel experience, Star Alliance member airlines are among the most respected in the world.
In order to become members, all airlines must comply with the highest industry standards of customer service, security and technical infrastructure, it added.
