Total travel time from Houston to Singapore runs 17½ to 22 hours, depending on the gateway you pick and how long the layover lasts between flights.

What is the time difference between Houston and Singapore?
Singapore's clocks run 13 hours ahead of Houston's during daylight time, which is why a Monday evening departure ends with a Wednesday arrival in the city.
How much can I save booking business class through Business-Class.com?
Business class fares from Houston to Singapore are often about 34% below standard published prices, since connecting itineraries over Doha or Hong Kong are priced differently from nonstop products.
When is the best time to book business class flights from Houston to Singapore?
Book 3 to 5 months ahead for Singapore, and earlier for the Formula 1 race weekend at Marina Bay in autumn or for Chinese New Year in late winter, when regional demand rises.
Can I change or cancel my Houston to Singapore business class booking?
Because a second carrier probably flies the Doha or Hong Kong leg, change and refund terms may differ by segment, so check each fare rule before paying and ask whether one ticket covers both flights.
