A frequent flyer number is a unique identifier assigned to travellers enrolled in airline loyalty programs. This number tracks mileage accrual, rewards status, and benefits such as seat upgrades, priority boarding, and waived baggage fees. Frequent flyer programs are structured with tiered status levels, where travellers who fly often gain access to VIP perks like lounge access, faster security screening, and flexible ticket options.

For business travellers, linking a frequent flyer number to corporate bookings ensures maximum benefits over time. Many companies encourage employees to enrol in these programs to accumulate personal rewards while maintaining travel cost efficiency. By using a travel agency that optimizes frequent flyer benefits, businesses can ensure their travellers earn rewards while securing the best rates and perks available across different airline alliances.
