Boston Warwick drives transformative change for airlines, airports, and aviation stakeholders. Its expert team, with decades of experience, delivers high-impact projects in flight operations, fleet valuations, and M&A, empowering clients with strategic insights. This week’s report unpacks critical developments from March 16-22, 2026, including Atlas Air’s landmark A350F freighter order with Rolls-Royce, Riyadh Air’s detailed 15-route summer network plan, antitrust clearance for the Allegiant-Sun Country merger, and Southwest’s network refinements.
Airlines
Southwest Airlines announced it will discontinue all service at Chicago O’Hare (ORD) and Washington Dulles (IAD) effective June 4, 2026, while continuing to serve the metros via Midway (MDW), BWI, and DCA. The move is part of ongoing network optimization to focus on higher-performing gateways. This shift allows Southwest to streamline operations and redeploy capacity amid evolving passenger flows and competitive pressures in major hubs.
Southwest Airlines also expanded its international reach through a new interline agreement with All Nippon Airways (ANA), enabling single-ticket journeys with through-checked baggage via six U.S. gateways. The partnership builds on Southwest’s “virtual global network” strategy with partners in Asia and Europe. It enhances customer options without committing to its own long-haul fleet.
Mergers, Acquisitions & Finance
Allegiant Air and Sun Country Airlines received early U.S. Department of Justice antitrust clearance for Allegiant’s proposed acquisition of Sun Country, with the Hart-Scott-Rodino waiting period terminated ahead of schedule. The $1.5 billion deal is now expected to close in Q2 or Q3 2026, subject to DOT and shareholder approvals. The combination will create a larger leisure-focused carrier with broader network reach and greater value creation for stakeholders.
Atlas Air Worldwide placed the largest order to date for Trent XWB-97-powered Airbus A350F freighters—20 aircraft powered by 40 Rolls-Royce engines—under a comprehensive TotalCare service agreement. This marks Atlas as the first A350F customer in the Americas for this engine type and the biggest aircraft order in the company’s history. The deal underscores confidence in the A350F’s efficiency and reliability for global cargo operations starting in 2029.
Airport Developments
Riyadh King Khalid International Airport (RUH) saw Riyadh Air secure 5,591 slot movements for summer 2026 across 15 planned destinations. The filing signals strong infrastructure readiness for the carrier’s expansion at its hub. This development supports Saudi Vision 2030 by positioning Riyadh as a major global aviation connector.
Industry Innovations & Services
Rolls-Royce advanced its Trent XWB-97 program with durability enhancements (third phase entering service in 2028) and the landmark Atlas Air TotalCare contract. The engine has already accumulated over four million flying hours with proven reliability. These innovations transfer maintenance risk to Rolls-Royce while boosting availability, efficiency, and time-on-wing—key advantages for freighter operators adopting the A350F.

Key Watch Items
Airbus widebody deliveries received a major boost from Atlas Air’s 20-unit A350F commitment (the largest Trent XWB-97-powered order yet). The freighter variant’s 2029 entry into service for Atlas strengthens the widebody backlog and highlights sustained demand beyond passenger models.
Rolls-Royce engine production recovery gained momentum with the Atlas Air order for 40 Trent XWB-97 engines plus TotalCare coverage. Executive comments emphasize the engine’s durability upgrades and operational certainty, reinforcing Rolls-Royce’s position in the widebody powerplant market.
Riyadh Air launch timeline advanced with slot allocations for an initial 15-destination network (including London Heathrow, Dubai, Cairo, Paris CDG, Manchester, Madrid, and key Asian points). Limited readiness flights continue, with full commercial services targeted soon after new aircraft deliveries; the carrier aims for over 100 destinations by 2030 under Vision 2030.
New routes from existing/new airlines include Riyadh Air’s planned services to Amman, Bangkok, Islamabad, Jakarta, Kuala Lumpur, Lahore, Manila, Mumbai, and more (many currently Saudia-dominated or unserved from RUH). Southwest’s simultaneous exits from ORD and IAD and its ANA interline expansion further reshape connectivity options for passengers.
