This is a great deal that will definitely not last long. Fly from Los Angeles or New York to Kuala Lumpur and then return from Bangkok. The round trip flight will cost only $397 from LAX and $480 from JFK. These prices are showing for All Nippon Airways which is a great airline. There’s availability in September and October 2018.
Amazingly low prices, especially from LAX. Travel between Kuala Lumpur and Bangkok is very cheap, probably $30-$40, so that shouldn’t be an issue. And it gives you the option of visiting both places.
