Singapore Airlines Business Class A350-900 SFO-SIN (2025)

Flying across the Pacific in premium cabin experience isn’t just about getting from point A to point B—it’s about savoring every moment of the journey. When it comes to luxury air travel, Singapore Airlines consistently ranks among the world’s finest carriers, and their business class seat configuration on the A350-900 represents one of their most refined products. In this comprehensive review, I’ll take you through my recent 15+ hour journey from San Francisco to Singapore, detailing everything from lounge access to landing.

Singapore Airlines has long held a revered position in the aviation industry, known for exceptional service quality and attention to detail. The Airbus A350-900 serves as a flagship aircraft for their long-haul routes, combining fuel efficiency with passenger comfort.

Whether you’re considering using KrisFlyer miles or investing cash in this premium product, this review will help you decide if the Singapore Airlines Business Class experience justifies its price tag.

“The journey of a thousand miles begins with a single step—preferably one onto a Singapore Airlines A350-900.” — Frequent flyer wisdom

Pre-Flight Experience

Booking Process

I booked this Singapore Airlines Business Class seat approximately four months in advance, using 95,000 KrisFlyer miles transferred from American Express Membership Rewards. Cash fares for this route typically hover between $4,000-$5,500 round trip, depending on season and demand.

KrisFlyer sweet spots worth noting:

• Saver awards between US West Coast and Singapore require 95,000 miles one-way
• Advantage awards (more availability) cost 130,000 miles one-way
• Waitlist feature allows you to be notified if Saver space opens up
• Fifth Freedom routes (like SFO-HKG) offer excellent value at 65,000 miles

When selecting seats, I opted for 18K—a window seat in the mini-cabin behind first class. This area features just two rows of seats (rows 17-18) in a 1-2-1 configuration, creating an exclusive atmosphere that feels almost like a private jet.

Check-In Experience at SFO

Arriving at San Francisco International Airport three hours before departure, I headed straight to the dedicated Singapore Airlines premium check-in counters. Despite traveling during the morning rush, I waited less than two minutes before being assisted by an impeccably dressed agent.

The check-in process was swift and efficient—a hallmark of Singapore Airlines’ operational excellence. My boarding pass was issued on heavy card stock rather than flimsy thermal paper, a small touch that reinforces the premium experience.

As a Business Class passenger, I received:

• Priority security lane access
• Priority immigration clearance
• 40kg checked baggage allowance (2 bags up to 20kg each)
• Additional 7kg hand luggage allowance

Lounge Experience

Singapore Airlines utilizes the United Polaris Lounge at SFO for its premium passengers—a wise choice given its exceptional quality. Located near Gate G92, the 28,000 square foot space offers a refined atmosphere that surpasses many dedicated airline lounges.

Polaris Lounge Highlights:

• Location: International Terminal G, near Gate G92
• Access: Business and First Class passengers on Star Alliance carriers
• Hours: 6:30 AM to 1:00 AM daily

Area	Description	Standout Feature
Dining Room	À la carte restaurant service	Seared salmon with quinoa salad
Buffet	Self-service hot and cold options	Made-to-order noodle bar
Bar	Full-service cocktail bar	“Paper Plane” signature cocktail
Quiet Suites	Private relaxation spaces	Comfortable daybeds with Saks bedding
Shower Suites	Hotel-quality shower facilities	Cowshed toiletries

The culinary highlight was the dining room’s menu, featuring dishes that rival upscale restaurants. I ordered the seared sea bass with seasonal vegetables, paired with a California Chardonnay. The quality far surpassed typical lounge fare, setting a high bar for the in-flight meal service to follow.

Eight shower suites provide a refreshing pre-flight experience, stocked with Cowshed toiletries and plush towels. Reservations are recommended during peak hours.

Boarding & First Impressions

The Boarding Process

Boarding began precisely 45 minutes before departure, with a dedicated lane for Business Class and PPS Club/KrisFlyer Gold members. The gate agents processed boarding passes efficiently, maintaining Singapore Airlines’ reputation for operational excellence.

Walking through the jet bridge, I felt the familiar excitement that comes with boarding a premium cabin. Two flight attendants in their iconic Singapore Girl kebaya uniforms greeted me at the door, checking my boarding pass and directing me to my seat with genuine warmth.

Aircraft Specifications

The Singapore Airlines A350-900 features 42 Business Class seats in a 1-2-1 configuration, ensuring direct aisle access for every passenger. The cabin is divided into two sections: a mini-cabin with 8 seats (rows 17-18) and the main cabin with 34 seats (rows 19-25).

Best seats for different travelers:

• Solo travelers: Any “A” or “K” window seat
• Couples: “D” and “F” center seats (though not true couples seats)
• Extra privacy: Row 19 (bulkhead) has larger footwells and more space
• Avoid: Rows 22 and 24 (near galleys and lavatories)

The A350-900 itself deserves special mention. This aircraft features:

• Higher cabin pressure (6,000 ft equivalent vs. 8,000 ft on older aircraft)
• Enhanced humidity (15-20% vs. 5-10% on older aircraft)
• Quieter cabin (approximately 52 decibels in cruise)
• Larger windows with electrochromic dimming
• LED mood lighting that helps combat jet lag

These environmental factors may seem subtle, but over a 15+ hour journey, they significantly reduce fatigue and improve passenger experience.

The Business Class Seat

Settling into seat 18K, I was immediately impressed by the design aesthetic. Singapore Airlines’ Business Class seat on the A350-900 strikes a balance between sophisticated elegance and functional comfort.

Seat specifications:

• Width: 28 inches (seat cushion: 25 inches)
• Bed length: 78 inches when fully flat
• Pitch: 60 inches
• Monitor size: 18 inches
• Power: Universal outlet + 2 USB ports

Storage options include:

• Side console compartment (fits laptop, tablets)
• Literature pocket (magazines, menus)
• Small cubby for personal items
• Shoe storage beneath the ottoman

The seat features hand-stitched leather by Poltrona Frau, the same company that crafts Ferrari interiors. The color scheme combines warm browns with touches of orange and beige, creating an inviting environment.

One design quirk worth noting: due to the seat’s angle, when converted to bed mode, you need to sleep diagonally to fully stretch out. This isn’t an issue for most travelers, but very tall passengers (over 6’3″) might find it slightly constraining.

The Service Experience

Welcome Aboard

The welcome aboard experience set an exceptional tone for the journey ahead. Within moments of settling into my seat, a flight attendant approached with a tray of welcome drinks—champagne, orange juice, or Singapore Airlines’ signature cocktail, the Silver Kris Sling.

I opted for the champagne (Charles Heidsieck Brut Réserve) served in a proper glass flute, not plastic. This was accompanied by a hot towel presented with silver tongs—small details that elevate the experience.

The cabin manager personally greeted each Business Class passenger, addressing me by name and thanking me for choosing Singapore Airlines. This personal touch creates an immediate connection that few airlines manage to achieve.

The Cabin Crew

The legendary Singapore Girl service isn’t just marketing—it’s a tangible difference you experience throughout the flight. The crew demonstrated an exceptional balance between formal professionalism and genuine warmth.

During our flight duration of 15.5 hours, I observed:

• Call buttons answered within 30 seconds
• Names remembered without reference to seat numbers
• Proactive service without being intrusive
• Genuine conversation that never felt rehearsed

One particularly impressive moment: after mentioning in passing that I enjoyed photography, a flight attendant later pointed out spectacular cloud formations visible from my window—a thoughtful gesture that showed attentive listening.

Amenities

The amenity kit contents from Penhaligon’s of London came in an elegant pouch containing:

• Quercus facial mist
• Lip balm
• Hand lotion
• Facial moisturizer
• Wellness oil (for relaxation)
• Dental kit
• Socks
• Eye mask

Additional amenities available on request included:

• Slippers (provided at seat)
• Eyeglass cleaning cloth
• Shaving kit
• Dental kit
• Sewing kit
• Earplugs

The bedding deserves special mention. When ready to sleep, the crew provided:

• A plush mattress pad
• Two full-size pillows
• A lightweight but warm duvet
• 100% cotton sleeper suit (pajamas) on request

In-Flight Entertainment & Connectivity

KrisWorld Entertainment System

The KrisWorld in-flight entertainment system features an 18-inch HD touchscreen that rivals many home televisions in clarity and responsiveness. Content selection is truly impressive, with over 1,800 entertainment options:

• 300+ movies (new releases, classics, international)
• 550+ TV programs
• 330+ music albums
• 20+ radio channels
• 100+ games
• e-magazines and newspapers

The system features a highly intuitive interface with personalized recommendations based on viewing habits. The noise-cancelling headphones provided excellent sound quality, though audiophiles might still prefer their personal headsets.

Standout features:

• “Favorites” list that saves across flights
• “Resume Play” functionality
• Screen mirroring with the Singapore Airlines app
• Moving map with multiple view options
• Exterior cameras viewable during takeoff and landing

Wi-Fi Service

Wi-Fi connectivity on this A350-900 utilized Panasonic’s latest generation system, providing better performance than older aircraft in the fleet. Business Class passengers receive a complimentary 100MB data package, with additional packages available for purchase:

Plan	Data	Price
Chat	30MB	$3.99
Pro	200MB	$15.99
Premium	500MB	$29.99

Connection speeds averaged 4-6 Mbps for downloads and 1-2 Mbps for uploads—sufficient for email, messaging, and light browsing, but not ideal for video streaming. Coverage remained consistent throughout the flight, even over remote Pacific regions.

Dining Experience

First Meal Service (Lunch)

Singapore Airlines’ reputation for exceptional in-flight meal service is well-deserved. Approximately 30 minutes after takeoff, lunch service began with table setup featuring linen tablecloths and proper silverware.

Wine and champagne selection included:

• Charles Heidsieck Brut Réserve
• 2018 Puligny-Montrachet 1er Cru “Les Folatières” (white)
• 2015 Château Lagrange, Saint-Julien (red)
• 2017 Cloudy Bay Te Koko Sauvignon Blanc (white)
• 2014 Rockford Basket Press Shiraz (red)

The menu featured both Western and Asian options:

Appetizer:

• Satay with onion, cucumber, and spicy peanut sauce
• Fresh bread selection with olive oil

Main Course options:

• Sous vide beef tenderloin with truffle sauce
• Lobster Thermidor (via Book the Cook pre-order)
• Chicken rice (Singapore specialty)
• Vegetarian biryani

I had pre-ordered the Book the Cook Lobster Thermidor, a signature dish that lived up to its reputation. The lobster was tender and flavorful, not overcooked as seafood often is at altitude. It was served with buttered asparagus and saffron rice that complemented the rich sauce perfectly.

Dessert:

• Chocolate mousse cake with raspberry coulis
• Cheese plate with crackers and fruit
• Selection of fresh fruits

The meal concluded with Illy coffee and TWG tea options, with the Sencha green tea providing a perfect palate cleanser.

Mid-Flight Refreshments

During the long-haul flight comfort period, a comprehensive snack menu was available on demand, including:

• Lobster and fennel salad
• Dim sum selection
• Ramen noodles
• Ice cream
• Fresh fruit plate
• Assorted sandwiches

I ordered the dim sum about 7 hours into the flight, which arrived beautifully presented with three types of dumplings, char siu bao, and a small side of chili oil. The quality was remarkably good for mid-flight dining.

Second Meal Service

Approximately 2 hours before landing in Singapore Changi Airport, the second meal service began. This pre-arrival dinner featured:

Starter:

• Mesclun salad with balsamic vinaigrette

Main Course options:

• Pan-seared sea bass with lemon butter sauce
• Beef bourguignon with mashed potatoes
• Wanton noodles (Singapore specialty)

I selected the sea bass, which arrived moist and flavorful—a feat considering we were 13+ hours into the flight. The accompanying vegetables retained their texture and flavor, avoiding the mushiness that often plagues in-flight vegetables.

Dessert:

• Mango pudding with fresh berries

This lighter pre-arrival meal was perfectly timed and portioned, providing sustenance without heaviness before landing.

Sleep Experience

The Singapore Airlines Business Class Bed

The seat privacy and comfort transforms into a truly flat bed measuring 78 inches in length. The conversion process is entirely electronic, controlled via intuitive buttons at the seat.

When I was ready to sleep (about 4 hours into the flight), a flight attendant offered turndown service, which included:

1. Converting the seat to fully flat position
2. Adding a plush mattress pad
3. Providing a second pillow
4. Offering the duvet

Sleep quality factors:

• Footwell space: Adequate but not overly generous
• Bed firmness: Medium-firm with good support
• Privacy: Side wings provide good isolation
• Noise level: Minimal (especially with provided earplugs)
• Temperature: Well-controlled with individual air nozzles

I managed to sleep for nearly 6 uninterrupted hours—a testament to the comfort of the bed and the quiet A350 cabin. The herringbone seat layout ensures that even when fully reclined, you never have direct sight lines to other passengers, enhancing privacy.

Bathroom and Facilities

The A350-900 features three lavatories for Business Class: one at the front and two at the rear of the cabin. All were consistently maintained throughout the flight, with flight attendants checking and cleaning after each use during busy periods.

The bathrooms feature:

• Penhaligon’s hand soap and lotion
• Cotton hand towels (instead of paper)
• Additional amenities (mouthwash, facial mist)
• Fresh orchid in a small vase (a signature Singapore Airlines touch)

While not as spacious as bathrooms on larger aircraft like the A380, they remained spotless throughout the journey—no small feat on a full flight.

Arrival Experience

Approach to Singapore

As we began our descent into Singapore, the cabin crew prepared the cabin while offering a final round of drinks. The captain provided comprehensive arrival information, including gate number, baggage claim details, and current weather in Singapore (a typical 32°C/89°F with high humidity).

The approach offered spectacular views of Singapore’s coastline and the ships dotting the Singapore Strait—a fitting introduction to this maritime nation. The A350-900‘s large windows and clear glass made photography a joy.

Arrival at Changi Airport

We touched down at Singapore Changi Airport Terminal 3 exactly 7 minutes ahead of schedule—Singapore Airlines’ operational precision on display once again. Business Class passengers were invited to deplane first, and I was stepping into the jet bridge within minutes of arrival.

The airline service evaluation continues beyond the aircraft door. Singapore Airlines excels in this regard with:

• Fast-track immigration cards distributed before landing
• Ground staff stationed at the gate to assist with connections
• Premium lane access for immigration
• Priority baggage handling

My checked bag appeared on the carousel just 15 minutes after reaching the baggage claim area—impressive efficiency for an airport of Changi’s size.
