I will be home in less than 1 month time. Managed to get a cheap return ticket 2 days before with Lufthansa. Air Asia, Malaysia Airlines and Thai Airways are expensive. Air Asia charges 734oBaht, Malaysia Airlines 7640Baht both for return and Thai Airways 9500+ Baht for only one way. This german national carrier offers the cheapest among all which I only paid 470Baht for ticket price plus 4550Baht for taxes. Lufthansa doesn’t fly directly to Malaysia. Kuala Lumpur is their extra destination. They only operate 2 or 3 flights a week between Kuala Lumpur and Bangkok. Other than Malaysia, Lufthansa also do fly to Ho Chih Minh City from Bangkok.
