Singapore

Singapore's aviation sector is a cornerstone of the national economy, centered around Changi Airport (SIN), consistently ranked among the best in the world. The country serves as a global connectivity hub. The primary regulatory body is the Civil Aviation Authority of Singapore (CAAS), which oversees safety, economic regulation, and aeronautical infrastructure. In 2026, Singapore maintains an "open skies" policy and upholds rigorous standards of safety and operational efficiency under the aegis of the Chicago Convention.

• Passport: Must have a minimum validity of 6 months from the date of arrival.
• SG Arrival Card (SGAC): All visitors must submit the SG Arrival Card electronically within 3 days prior to arrival. This is not a visa, but a mandatory health and immigration declaration.
• Visas: Singapore maintains visa-exemption policies for many nationalities (including Brazilian citizens for tourism up to 30 days). Use the "Visa Check" tool on the ICA website to confirm entry requirements.
• Biometric System: Changi Airport utilizes automated immigration systems (facial and iris biometrics) for visitors, eliminating the need for physical passport stamps in many cases.

Singapore does not have specific "passenger rights" legislation comparable to the European Union's Regulation 261/2004 or Brazil's ANAC Resolution 400. The country is a signatory to the Montreal Convention, which governs the liability of air carriers in the event of delays, cancellations, or lost baggage.

• Compensation: Compensation is determined primarily by the airline’s own Terms and Conditions (Contract of Carriage) and the standards set by the Montreal Convention.
• Material Assistance: In cases of prolonged delays, the standard practice for airlines operating at Changi Airport is to provide basic assistance (food and accommodation); however, there is no national law mandating fixed compensation amounts for inconvenience unless proven damages fall within the scope of the Convention.
• Recourse: For unresolved disputes, passengers may seek assistance from CASE (Consumers Association of Singapore).

There is no single national regulation governing mandatory baggage allowances for commercial flights.

• Pricing Freedom: Airlines have the autonomy to define their baggage policies (unbundled or full-service models).
• Safety Regulations: The CAAS imposes strict restrictions regarding prohibited items and carry-on liquid limits (international 100ml per container rule), aligned with ICAO guidelines. Airlines are required to clearly communicate these limits at the time of purchase.

Singapore enforces some of the world's strictest sanitary regulations, managed by the Animal & Veterinary Service (AVS).

• Country Classification: The country categorizes nations (A, B, C, D) based on rabies risk.
• Requirements: Obtaining an Import License prior to travel is mandatory. Pets must be microchipped, vaccinated against rabies, and undergo serological testing.
• Quarantine: Depending on the country of origin, a minimum stay of 30 days in official quarantine facilities may be mandatory.
• Restrictions: Specific dog breeds may be prohibited or require mandatory insurance and muzzling.

• Unaccompanied Minors: Airlines operating in Singapore follow IATA standards for the Unaccompanied Minor (UM) service, which is generally mandatory for children between 5 and 11 years of age.
• Authorization: Although Singapore does not formally require a government-certified "exit permit" for foreign minors, it is highly recommended that minors traveling with only one parent or guardian carry a consent letter in English to prevent questioning at immigration and to combat human trafficking.

Singapore is recognized for its excellent physical accessibility.

• Airports: Changi Airport complies with international accessibility standards for Passengers with Reduced Mobility (PRM), offering free wheelchair assistance (when requested in advance from the airline), lowered service counters, and accessible restroom facilities.
• Transportation: The use of mobility aids is permitted at no extra cost. It is recommended to inform the airline at least 48 hours in advance of any specific requirements.
