CAAS

The Civil Aviation Authority of Singapore (CAAS) is the regulator responsible for overseeing civil aviation in Singapore. Its jurisdiction covers aviation safety, air navigation, the licensing of aviation personnel and the economic regulation of air services operating within and from Changi (SIN) and Seletar (XSP) airports. CAAS works to grow Singapore's air hub, following ICAO (International Civil Aviation Organization) standards.

Official changes from this authority that affect passengers appear in this guide's updates as they are published. Each one is checked against the official document before it goes live.

CAAS does not impose fixed baggage fees, allowing carriers to determine their own commercial policies (low-cost vs. full-service models). However, in 2026, transparency standards require:

• Fare transparency: airlines must clearly show the total ticket price and the cost of optional services, such as checked baggage, before payment.
• Hand baggage: dimensions and weight are set by each airline; security screening at Changi follows the international rules on liquids, batteries and prohibited items.
• Claims: for loss or damage, the Montreal Convention, ratified by Singapore, applies, with a liability limit per passenger (1,519 SDR since 28 December 2024).

The transportation of animals in Singapore is strictly regulated by NParks (Animal & Veterinary Service - AVS) in partnership with CAAS:

• In-Cabin Prohibition: On most Singapore-based airlines (e.g., Singapore Airlines), animals are not permitted in the passenger cabin (except for certified service/guide dogs).
• Cargo Manifest: Animals must be transported as manifested cargo, complying with quarantine protocols.
• Sanitary Requirements: An import/export license issued by NParks, a rabies vaccination certificate, and a valid microchip are mandatory. The process must be initiated at least 30 days in advance.

• Seats: ask for seats together when booking; seat selection rules and fees vary by airline.
• Equipment: Strollers and car seats are permitted at the boarding gate (gate-check) at no additional cost, provided they comply with the carrier's dimension requirements.
• Infant Assistance: Onboard bassinets are limited and must be booked in advance, subject to the aircraft's technical availability.

CAAS requires all operators serving Singapore airports to offer support to passengers with reduced mobility:

• Assistance Request: The MEDIF (Medical Information Form) is required only for passengers needing specialized medical support (oxygen, stretchers). It must be submitted at least 48 to 72 hours in advance.
• Wheelchairs: Wheelchair service is provided free of charge at Changi Airport and must be requested directly with the airline at least 48 hours before departure.
• Priority: Implementation of priority lanes (Fast Track) for passengers with invisible or physical disabilities at all security checkpoints.
