Singapore Airlines Business Class to Singapore (SIN) operates the longest commercial flights in the world: JFK-SIN at 18h 30m and EWR-SIN at 18h 50m on the A350-900 ULR. Plus the A380 from LAX, SFO, and JFK with the optional Singapore Suites upgrade (First Class). Daily from 4+ US gateways.
Round-trip consolidator fare bands in shoulder season (April-May, September-October). Peak summer and holiday windows typically run 30-50% higher.
| US Origin | Fare band | Flight time | Cabin / aircraft |
|---|---|---|---|
| JFK | $3,800-$5,400 | ~18h 30m | Daily A350-900 ULR Business (longest commercial flight) |
| EWR | $3,800-$5,400 | ~18h 50m | Daily A350-900 ULR Business (second-longest) |
| LAX | $3,400-$4,900 | ~17h | Daily A380 Business + Suites option |
| SFO | $3,400-$4,900 | ~17h | Daily A380 Business + Suites option |
| SEA | $3,800-$5,000 | ~16h | Daily A350-900 Business |
| ORD | $4,200-$5,800 | ~16h | Daily A350-900 Business via NRT or direct |
Singapore Airlines flight SQ23 (JFK-SIN) is the longest non-stop commercial flight in the world at 18h 30m. SQ21 (EWR-SIN) is a close second at 18h 50m. Both operate the A350-900 ULR (Ultra Long Range), configured with no Economy seats: 67 Business + 94 Premium Economy seats only, for a quieter, less crowded long-haul cabin.
The A350-900 ULR Business cabin is 1-2-1 reverse-herringbone lie-flat (not the same as the A380 upper-deck Business, which is 1-2-1 with wider seats and additional space). 28-inch seat width, 78-inch bed length, 18-inch IFE screen. The ULR cabin was redesigned specifically for ultra-long-haul comfort: better mattress, more humidity control, dual-mode (day/night) IFE.
Singapore Airlines operates the A380 from LAX and SFO to Singapore. The A380 Business cabin (upper deck, 1-2-1 lie-flat) is widely considered the most comfortable Business Class cabin in the air, with 30-inch seat width (vs 22 inches on most competitors) and a 79-inch bed.
On the A380, Singapore offers the unique Singapore Suites cabin: 6 private suites in the upper deck nose, each a true 1-suite layout with closing door, separate bed (built into the suite), seating that converts to a bed, dining for two with a partner in adjacent suite (the partition lowers), and the Krug-Champagne-by-default service. Pricing is in the $9,000-$15,000 range round-trip on the published fare; consolidator pricing rarely below $7,000-$9,000. The Suites cabin is considered the gold standard premium cabin globally.
Singapore Airlines KrisFlyer is the home program but rarely the best value. KrisFlyer charges 92,000 miles one-way US-SIN Business Saver + $300-$400 in fees on Singapore-operated flights. Better redemption: Singapore Saver Award space is sometimes available 12+ months out at lower rates (e.g. 72,000 miles JFK-FRA Business via Singapore's partner network).
For non-Singapore-metal awards through Star Alliance partners: Aeroplan (Air Canada) charges 87,500-105,000 miles one-way US-SIN Business + $300-$400 fees. United MileagePlus charges 80,000-110,000 miles. Aeroplan typically offers better Saver-level availability for the same routes.
Through a consolidator in shoulder season: JFK-SIN or EWR-SIN Business (the A350-900 ULR non-stop) typically $3,800-$5,400 round-trip; LAX-SIN or SFO-SIN A380 Business $3,400-$4,900 (often cheaper than the East Coast non-stop because of competitive pricing on the LA route); SEA-SIN $3,800-$5,000; ORD-SIN $4,200-$5,800.
Yes, comfortable for most travelers. The A350-900 ULR is a quieter cabin (no Economy in the back) with better humidity control and a redesigned Business cabin (28-inch wide seats, 78-inch beds, premium bedding). The flight crew is the most experienced ultra-long-haul crew at Singapore Airlines. The 18+ hour flight is genuinely tolerable in Business. Whether it is preferable to a 1-stop routing via DOH on Qatar (US-DOH-SIN, total ~22 hours including layover) is a personal preference; many travelers prefer the non-stop despite the length.
Yes, but availability is constrained. Singapore Suites is a 6-seat cabin only on A380 routes (LAX-SIN and SFO-SIN). Through a consolidator, Singapore Suites round-trip typically prices $7,000-$9,000 (vs $11,000-$15,000 retail on singaporeair.com). Book 4-6 months ahead; the cabin sells out quickly on peak dates. For travelers who specifically want the Singapore Suites experience, this is the most premium commercial flight available.
Non-stop is preferable for time + simplicity but more expensive. JFK-SIN non-stop in 18.5 hours saves 2-4 hours over a typical Tokyo or Hong Kong connection (NRT or HND connection adds 4-6 hours total trip time). One-stop alternatives: ANA via NRT (JFK-NRT-SIN), Cathay via HKG (JFK-HKG-SIN), or Qatar via DOH (JFK-DOH-SIN). One-stop options are often $500-$1,500 cheaper than the non-stop. For business travelers prioritizing time, non-stop. For leisure travelers prioritizing total cost, one-stop wins.
Singapore configured the A350-900 ULR with no Economy and no First Class - just 67 Business + 94 Premium Economy seats. The aircraft's extended-range capability means it can fly 9,500+ miles, but the trade-off is fewer revenue seats per flight. By offering only Business + Premium Economy, Singapore optimizes the route for premium-cabin travelers; the cabin is quieter and feels less crowded than a typical long-haul A350. For travelers who want the ultra-long-haul experience without the cabin density of a 3-class aircraft, the ULR is the right pick.
A contracted consolidator typically prices 30-60% below the airline's published Business Class fare on the same flight. Same airline, same cabin, same seat, same lounge access, same baggage. Only the fare class differs - consolidators access privately filed fare buckets (I, Z, P, R or airline-specific codes) that the airline files for distribution only through accredited agencies in exchange for volume commitments.
Yes, in almost all cases. Tickets are issued in standard fare classes that earn miles in the airline's frequent flyer program at the rates published for the fare class. Some heavily-discounted contract buckets earn at 50-75% of distance flown instead of 125-150%. We confirm the exact earning rate on every quote before you ticket.
