Payment Insights & Benchmarks

Merchants in the air travel sector, specifically for airlines like China Southern Airlines, should be prepared for unique payment challenges compared to standard e-commerce. Factors such as ticket prices, customer demographics, and payment preferences significantly influence payment processes and acceptance rates.

Payment methods

Credit cards: the predominant method, but may face high decline rates, especially from international issuers.

• Debit cards: widely used in local markets but often have lower acceptance abroad.
• E-wallets: increasingly accepted as alternatives, providing travelers with convenient payment options.
• Bank transfers: popular for high-value transactions, yet may result in longer settlement times.
• Travel vouchers and loyalty points: commonly utilized, but require careful management of liability and fraud risk.

Authentication & security

Strong customer authentication (SCA) processes like 3DS are often implemented, which can lead to increased friction in the payment flow.

• Regular monitoring for fraud patterns is essential, as the travel industry is susceptible to ticket fraud and chargebacks.
• Implementation of robust fraud detection tools is advisable due to the high-value nature of airline transactions.

Benchmarks (indicative, not guaranteed)

MDR: typically higher than standard e-commerce due to perceived risk in travel bookings.

• Rolling reserves: may be applied, especially for new or high-risk accounts.
• Settlement times: generally extended (7-14 days), particularly for international transactions.
• Chargeback ratios: often higher than retail averages, necessitating vigilant account monitoring.
• Approval rates: lower for credit cards, with better outcomes for local payment methods.

Key metrics to monitor

Authorization rates split by payment method and issuer.

• Chargeback ratios and dispute reasons categorized by fraud or service issues.
• Average sale price and frequency of bookings to identify trends.
• Customer payment preferences evolving over time to stay ahead of market shifts.

Risk & Compliance

Merchants under this MCC are closely scrutinized due to elevated financial and reputational risks associated with travel and aviation industries. PSPs and acquirers typically apply stricter controls, expecting merchants to proactively address fraud, chargebacks, and AML/KYC compliance.

Chargebacks & fraud

High incidence of friendly fraud (“I didn’t authorize this transaction”), where customers dispute flights due to changes in travel plans.

• Common fraud patterns include using stolen credit cards for flight bookings and intentionally charging back after traveling.
• Mitigation tools include behavioral analytics to monitor purchasing patterns, velocity checks for booking frequency, and fraud detection algorithms to flag suspicious transactions.

AML/KYC expectations

Strong customer identity verification (IDV) is required, with rigorous sanctions and politically exposed persons (PEP) checks on customers.

• Verification of source-of-funds is essential, particularly for high-value transactions or when booking multiple flights.
• Manual review triggers include large upfront payments, frequent bookings from the same customer, or transactions that deviate significantly from typical customer behavior.

Operational red flags

Lack of transparency regarding the ownership structure of the travel agency or hidden operators, raising concerns about accountability.

• Unverified marketing affiliates or travel agents funneling traffic without clear communication regarding their status or reputation.
• Absence of clear refund and cancellation policies, which can lead to increased disputes and chargebacks.
• Inadequate procedures for handling customer complaints and inquiries, potentially escalating chargeback rates.

Merchants under this MCC should prepare a complete onboarding package before approaching PSPs or acquirers. A well-structured submission improves approval chances and shortens review times.

• Various bilateral air service agreements that require specific licensing to operate international flights.

Geo-restrictions

Airlines are subject to national regulations which can restrict operations based on country-specific agreements.

• Certain countries may prohibit or limit flights from operators not meeting specific international or regional licensing requirements.
• Air travel regulations may vary significantly between regions, impacting service offerings based on local laws.

Certifications & audits

IATA Operational Safety Audit (IOSA) certification required for many airlines to demonstrate operational safety management.

• Compliance with the International Civil Aviation Organization (ICAO) standards needed for international flight operations.
• Annual safety and operational audits to maintain certification and comply with regulatory expectations.
