Five steps from research to ticketed booking. Every step is something our advisors do for you, but helpful to understand the process.
Pick the gateway. JFK and SFO offer non-stop Singapore Airlines service (the world's longest commercial flight at 18h 30m JFK-SIN). LAX, IAD, SEA need a Tokyo, Frankfurt, or Hong Kong connection.
Pick the carrier. Singapore Airlines is the canonical premium-cabin choice. ANA Business "The Room" plus a NRT-SIN connection is a strong alternative. United Polaris non-stop from SFO is the only non-SQ direct option.
Time the booking. Singapore Airlines saver award space opens 11 months out and goes fast on the non-stop ultra-long-range routes. For cash fares, 3-6 months out is the consolidator sweet spot.
Compare miles redemptions. Singapore KrisFlyer holds most Suites + Business saver space; Star Alliance partner programs (Aeroplan, LifeMiles) occasionally get Business but rarely Suites. Transferable from Amex, Chase, Citi, Capital One to KrisFlyer 1:1.
Lock the fare in writing. Verify aircraft (A350 ultra-long-range vs A380 has different cabin layouts), fare basis, baggage allowance, and refund rules before payment.
Three windows, three different price worlds.

Apr - May
Hot and humid but mostly dry. Best value Business Class window for vacation travelers.
Jun - Sep

Oct - Nov

Published Business Class US East Coast to Singapore typically runs $5,800 - $8,400 round-trip in peak season. Through a contracted consolidator, JFK-SIN Business round-trip is regularly $3,800 - $5,400 in shoulder season. SFO non-stop on Singapore Airlines is similar pricing.
Yes, in 2026. Singapore Airlines SQ23 / SQ24 between JFK and SIN runs roughly 18h 30m eastbound and 18h 50m westbound on a specially-configured A350-900 ultra-long-range. Business Class is the lowest cabin on this aircraft (no Economy seats). Often cited as the world's longest commercial flight.
For Suites specifically, miles win because Singapore Suites cash prices are extreme ($22,000+ round-trip published). KrisFlyer saver awards on Suites cost 95,000 miles + ~$200 one-way. Transfer from Amex MR 1:1. Saver Suites award space is limited, search 8-11 months out.
Singapore Suites (A380 only) are six fully-enclosed private suites with sliding doors, a separate seat and bed surface, Krug Champagne, and a la carte dining. Singapore Business (A350 + A380) is a 1-2-1 lie-flat Business cabin with no closing door, Veuve Clicquot, and excellent dine-on-demand service. Suites is a different category of product.
JFK-SIN non-stop on the A350 ultra-long-range. The cabin is specifically configured for ultra-long-haul comfort with extra noise insulation and humidity. The 18h 30m is a single sleep window timed to align with Singapore arrival. Two-stop routings via Tokyo or Frankfurt break the journey but disrupt sleep cycles.
Yes. Singapore is a major hub for Southeast Asia, with Business Class connections to Bali (Denpasar), Phuket, Bangkok, Ho Chi Minh, Jakarta, and Manila on Singapore Airlines, SilkAir (regional brand), and partner carriers. Multi-city Business Class itineraries through Singapore are priced reasonably as add-ons.
