For the vast majority of commercial airlines in 2026, passenger revenue far outweighs cargo revenue. According to IATA's 2026 forecast, the global airline industry expects roughly $751 billion from passenger transport compared to $158 billion from cargo. While cargo was a lifeline during the pandemic years, the return of massive international passenger demand has restored the traditional balance where passengers account for about 70-75% of total revenue. However, cargo remains a high-margin "hidden" profit center; many long-haul flights only become profitable because of the "belly cargo" carried beneath the passengers' feet. Only dedicated freighter airlines (like FedEx or UPS) or specific carriers in heavily industrial hubs see cargo revenues that rival their passenger operations.
