There are three variations of the first class cabin, although the Singapore Airlines Suites class is designated by Singapore Airlines as a "Class Beyond First" and uses a different fare code (R).

Introduced on 17 October 2006, the "New" First Class is offered only on Boeing 777-300 and Boeing 777-300ER aircraft. Designed by James Park Associates, it features a 35 in (89 cm) wide seat upholstered with leather and mahogany and a 23 in (58 cm) LCD screen. The seats fold out into a flat bed and are arranged in a 1-2-1 configuration.

Two Boeing 777-200 aircraft used on regional flights offer sleeper seats that are 21 in (53 cm) wide in a 2-2-2 configuration.

Business Class on the Airbus A380, Airbus A340-500, Boeing 777-300ER, a fully flat bed is available in a 1-2-1 configuration featuring 30 in (76 cm) of seat width. These seats are forward-facing, in contrast to the herring-bone configuration used by several other airlines offering flat beds in business class. The leather seats feature a 15.4 in (39.1 cm) diagonal screen size personal television, in-seat power supply and 2 USB ports. This seat is also being progressively introduced on Boeing 777-200ER aircraft.

On eight Airbus A380 aircraft, the first of which entered service in October 2011, Singapore Airlines extended the business class cabin to run the entire length of the upper deck, compared to the original configuration which shares the upper deck between 16 rows of business class and 11 rows of economy at the rear.

The new Economy class seats on the Boeing 777-300ER, Airbus A380-800, and Airbus A330-300 are 19.5 in (50 cm) wide, have in-seat power and have a 10.6in personal television screen which has a non-intrusive reading light under it, which can be used by folding the screen outwards. These are configured 3-4-3 on the Airbus A380, 3-3-3 on the Boeing 777, and 2-4-2 on the Airbus A330, as well as the upper deck of the Airbus A380. Other features include an independent cup holder (separate from the fold-out table) and a USB port. Singapore Airlines will start to introduce a similar design on board the Boeing 777 aircraft when they go through their cabin refits. The Boeing 777-300 is the first model to undergo refit and has introduced the product on the Singapore - Sydney route on 22 July 2009. Equipped with bigger 9-inch screens and AVOD in each seat. Available on all 18 refitted aircrafts (excluding 4 B777-200ER which has been retrofitted since January 2013).
