Capacity growth plans at the Gulf’s biggest hubs are coming under pressure as a shortage of CFM LEAP engines slows deliveries of Boeing 737 MAX and Airbus A320neo aircraft, adding a fresh bottleneck for airlines banking on narrowbodies to expand at Dubai, Doha and Riyadh.

LEAP Engine Shortage Hits Gulf Hubs as Narrowbody Demand Surges

LEAP Bottlenecks Collide With Record Narrowbody Backlogs

The LEAP family of engines, produced by the CFM International joint venture between Safran and GE Aerospace, powers all Boeing 737 MAX jets and a significant share of Airbus A320neo family aircraft. Recent financial and industry reports describe a constrained production environment, with LEAP deliveries rising but still lagging the ambitious output targets set by Airbus and Boeing as they chase record order backlogs.

Safran’s latest integrated report highlights continued stress in the LEAP supply chain, including material constraints and labor shortages that have limited the pace at which engine output can rise relative to demand. At the same time, Boeing has been forced to keep 737 MAX production well below pre‑crisis peaks, while Airbus has increased but not fully normalized A320neo family rates. The combined effect is fewer powered airframes reaching airline fleets than carriers had planned just a few years ago.

Industry analyses from consultancies and aviation data providers show that, between 2019 and 2024, global aircraft deliveries fell far short of pre‑pandemic trajectories. Narrowbody types led by the A320neo and 737 MAX remain heavily sold out for years ahead, with tens of thousands of LEAP engines required to clear backlogs. Each incremental disruption in engine manufacturing therefore has an outsized impact on delivery slots at the world’s busiest hubs.

While some Airbus aircraft use Pratt & Whitney’s geared turbofan, the shift of many carriers toward LEAP‑powered variants has deepened the exposure. Airlines that once saw engine selection as a secondary decision now find it central to whether their near‑term fleet plans can be executed as scheduled.

Emirates Eyes Narrowbody Growth From Dubai Amid Supply Squeeze

Publicly available fleet and order data show Emirates in the midst of a multiyear transformation of its widebody‑focused model, including a growing interest in feed traffic and thinner regional routes that favor single‑aisle jets. Although Emirates has not yet fielded a large 737 MAX or A320neo fleet comparable to some peers, its long‑term strategy for Dubai International Airport increasingly anticipates greater use of narrowbodies to relieve slot constraints and open new city pairs.

Emirates’ recent top‑up order for Airbus A350‑900s at the 2025 Dubai Airshow underscores how quickly long‑haul capacity is being refreshed, but it also highlights the imbalance with narrowbody growth. With A320neo and 737 MAX production tied closely to LEAP engine availability, industry forecasts suggest that Gulf carriers seeking to add single‑aisle lift at Dubai will have to plan around more modest delivery streams than their orderbooks alone might imply.

Consultant reports on Gulf aviation indicate that Emirates and its sister low‑cost carrier flydubai, a major 737 MAX operator, are both exposed to LEAP bottlenecks in different ways. For Emirates, the challenge lies in aligning future feed and regional capacity with hub growth at Dubai International and Al Maktoum International. For flydubai, already operating a large MAX fleet, any slippage in new aircraft arriving can slow route expansion and frequency increases that underpin connectivity for Emirates’ long‑haul network.

As Dubai International continues to rank among the world’s busiest international airports, even relatively small deviations from planned fleet growth can ripple through schedules, affecting connection banks and the distribution of traffic between widebody and narrowbody operations.

Qatar Airways Faces Capacity Planning Risks at Doha

Qatar Airways has a long history with engine‑related delivery disruptions, dating back to its highly publicized cancellation of early A320neo aircraft nearly a decade ago after problems linked to powerplants. While that dispute centered on a different engine type, current LEAP shortages mean the carrier now faces similar uncertainty as it weighs future narrowbody additions for Doha Hamad International Airport.

Recent airline fleet outlooks suggest that Qatar Airways is evaluating both 737 MAX and A320neo family options to support regional and medium‑haul growth across the Middle East, India and parts of Europe. Both choices, however, rely heavily on a steady flow of LEAP engines. With industry data pointing to a double‑digit percentage shortfall in LEAP shipments relative to earlier plans, near‑term delivery timelines are less predictable than airlines would prefer when building schedules and commercial strategies.

Market intelligence indicates that Doha’s role as a fast‑growing global transfer hub depends increasingly on right‑sizing capacity with fuel‑efficient narrowbodies on secondary routes that feed long‑haul widebodies. When LEAP‑powered aircraft arrive late, airlines face trade‑offs between extending the life of older jets, leasing additional lift at higher cost, or trimming frequencies on marginal routes.

For Qatar Airways, already balancing a complex fleet renewal across its widebody and narrowbody segments, engine‑constrained delivery slots can complicate recovery planning after major events and affect how rapidly new destinations are brought online from Doha.

Riyadh Air’s Launch Timeline Intersects With LEAP Constraints

Saudi Arabia’s emerging carrier Riyadh Air is building its strategy around transforming King Khalid International Airport into a large transfer hub alongside Saudi Arabia’s broader tourism ambitions. The airline has announced significant orders for new generation aircraft and has signaled that single‑aisle jets will be central for regional connectivity across the Gulf, Levant, and South Asia.

Analysis of Riyadh Air’s public order commitments indicates that its planned narrowbody fleet will be heavily tied to LEAP‑powered types, particularly the Boeing 737 MAX. As engine manufacturers and airframers continue to caution about supply chain headwinds, industry observers note that the startup’s ramp‑up schedule may have to be staged more gradually than originally envisioned.

Advisory firm assessments of the Saudi market suggest that the kingdom’s aviation strategy relies on synchronized development of airport infrastructure, national carriers and inbound tourism. Any delay in bringing fuel‑efficient narrowbodies into Riyadh’s operation can slow the rollout of new point‑to‑point routes and limit capacity during peak travel seasons, even as the airport gains gates and terminal space.

Riyadh Air has indicated publicly that it intends to differentiate through a modern, high‑specification fleet. Achieving that objective during a period of constrained LEAP output will likely require careful phasing of deliveries, potential interim leasing options and close coordination with manufacturers to secure production slots deep into the 2030s.

Global Engine Shortage Reshapes Capacity Strategies at DXB, DOH and RUH

Across Dubai, Doha and Riyadh, the common thread is that narrowbody capacity growth now depends as much on engine factory throughput as on airport expansion projects or passenger demand. Consultant studies emphasize that LEAP shortages, combined with earlier disruptions affecting other engine families, have become a structural feature of the post‑pandemic aviation landscape.

Fleet planning analyses show airlines in the region increasingly revisiting assumptions about utilization, retirement ages and fleet mix. Some carriers are extending the service life of older A320ceo and 737NG aircraft to bridge gaps created by delayed LEAP‑powered deliveries. Others are turning to the leasing market, where monthly rates for new A320neo and 737 MAX aircraft have climbed sharply as lessors absorb part of the timing risk.

For hub operators at DXB, DOH and RUH, the outcome is a more gradual build‑up of short and medium‑haul capacity than headline aircraft orders might suggest. Publicly available traffic forecasts still show robust growth over the coming decade, but with greater uncertainty around the exact timing of new route launches and frequency increases.

Industry reports indicate that engine manufacturers are investing heavily to raise LEAP production and address durability issues, with expectations of higher output in the second half of the decade. Until those gains materialize at scale, Emirates, Qatar Airways, Riyadh Air and their partners will be navigating a tight engine market that continues to shape how quickly the Gulf’s megahubs can grow.
