CAAS

The Civil Aviation Authority of Singapore (CAAS) is the regulatory body responsible for the oversight of civil aviation in Singapore. Its jurisdiction encompasses operational safety, air navigation, aeronautical personnel licensing, and the economic regulation of air services operating within and from Changi Airport (SIN) and Seletar Airport (XSP). CAAS serves as a facilitator for the growth of the Singapore air hub, ensuring compliance with ICAO (International Civil Aviation Organization) standards and implementing consumer protection policies aligned with CASE (Consumers Association of Singapore) guidelines.

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 display the total cost of travel (including checked baggage and fuel surcharges) at the time of initial booking.
• Carry-on Baggage: Standardization of permitted dimensions for overhead compartments to facilitate screening at the high-technology (CT) scanners installed at Terminal 4 and the new Terminal 5.
• Claim Rights: In the event of loss or damage, CAAS directs passengers to the standards of the Montreal Convention, which has been ratified by Singapore, establishing limits for financial liability per kilogram of baggage.

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.

• Seating: CAAS recommends, but does not mandate, that families with children under 12 be seated together. Airlines are encouraged to adopt free *Family Seating* policies to avoid additional costs.
• 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.
