Flights from Boston (BOS) to Bangkok (BKK)

Flight route information

Cathay Pacific offers flights to Bangkok Suvarnabhumi International Airport (BKK) from Boston Logan International Airport (BOS), with a layover in Hong Kong. Flights from BOS to BKK take around 19 hours 15 minutes, including the layover, and bring you to the main airport terminal in Bangkok.

Upon your arrival in Bangkok

The most convenient route to the city center is via taxi, which can be found outside the airport terminal and takes approximately 30 minutes. The Airport Rail Link offers another option to downtown Bangkok, getting you there in around 25 minutes.

A Brief introduction to Bangkok

Brimming with rich culture, renowned street food, and a pulsating nightlife, the capital city of Thailand offers plenty of memorable experiences for those who visit.

To experience Bangkok’s fascinating history and heritage, head to the island of Rattanakosin – home to the city’s opulent golden temples. Here, you can marvel at the ornateness of the Grand Palace, a building encrusted with gold and jewels that has been the official residence of the Thai monarchy for almost 250 years. Be sure to also visit the Temple of the Emerald Buddha, which is regarded as one of the most sacred Buddhist temples in all of Thailand.

For a taste of Bangkok’s delicious culinary delights, the vast array of street food on Yaowarat Road is a must-try. We recommend indulging in local favorites, such as ‘pad see ew’ (stir-fried flat noodles) and ‘tom yum’ (hot and sour soup). The city is also known for its energetic nightlife, with Banglamphu being the go-to hotspot for those seeking trendy nightclubs and hip bars.
