Aerospace giants Boeing and Airbus are managing material shortages and supplier delays that have constrained production of widebody jets. Components including engines, avionics, and composite panels remain scarce as airlines rush to expand capacity for revived international routes. Engineers said bottlenecks stem from uneven recovery among tier-two suppliers and logistical congestion. Delivery targets for 2026 could slip if procurement timelines do not stabilize. Despite headwinds, both manufacturers maintain strong order backlogs, reflecting durable long-haul travel recovery across global aviation markets.
