Aeroméxico has re-registered its last two aircraft from the Irish register to the Mexican register, a process that concluded on 2 December with the transfer of the Boeing 737-800s previously marked EI-RLA and EI-RLB to XA-SBG and XA-SBH.
Flight trackers show XA-SBG operating AMX flight 456 from Mexico City to Cancún, and XA-SBH on AMX flight 278 to Tijuana, marking the end of Aeroméxico’s foreign registration era.
The move aligns the carrier’s fleet of 148 aircraft under Mexican jurisdiction, following a series of similar transfers over the past 18 months. Aviation database ch-aviation confirmed the changes in its records, noting that the aircraft, leased from Dublin-based lessors, now operate with Mexican marks under the Aeroméxico Air Operator’s Certificate.
The re-registrations involved coordination between the Irish Aviation Authority and Mexico’s Federal Civil Aviation Agency. Documents filed with the Mexican Aeronautics Registry include bills of sale and lease amendments, with import authorisations from Mexican customs. Fees for the transfers totalled €45,000, covering administrative costs and maximum take-off weight calculations for the 737-800 type. The aircraft entered service on domestic routes from Mexico City to Guadalajara and Monterrey on 3 December.
Aeroméxico operates all-Boeing mainline fleet, comprising 787s, 737 MAX variants, and 737-800s, alongside Embraer 190s for regional services. The carrier maintains codeshare agreements with Delta Air Lines and other SkyTeam partners, serving over 90 destinations. The Irish registrations dated from 2017 sale-leaseback deals with lessors such as Avolon, which hold stakes in the airframes. Re-registration reduces administrative burdens under the Cape Town Convention, to which both Ireland and Mexico are parties.
The process reflects a broader trend among Latin American operators to consolidate registrations domestically. Volaris and VivaAerobus completed similar shifts earlier in 2025, citing operational efficiencies. Aeroméxico’s fleet now stands at 100 per cent Mexican-registered, with no foreign marks remaining. The airline reports no disruptions to its schedule of more than 600 daily flights from hubs in Mexico City and Monterrey.
Irish register updates for November 2025, published by the Irish Aviation Authority, list the cancellations effective 2 December. The aircraft logged 12,500 flight hours each under EI marks, primarily on transatlantic and intra-Mexico routes. Lessors retain ownership interests recorded in the International Registry, ensuring compliance with security protocols.
Aeroméxico plans fleet expansion with four additional 737 MAX 8 deliveries in 2026, all entering under Mexican registration from the outset. The carrier’s restructuring under Chapter 11 protection, concluded in 2024, facilitated these adjustments, with €1.2 billion in lease renegotiations. Passengers on the re-registered aircraft receive standard in-flight services, including Wi-Fi on select 737-800s.
The Federal Civil Aviation Agency verifies airworthiness certificates for the transferred planes, with inspections completed at Felipe Ángeles International Airport. Aeroméxico’s maintenance base in Mexico handles ongoing checks, supported by Boeing service agreements. The airline operates repatriation flights to Europe and the US, unaffected by the registration changes.
Ryanair DAC added five Boeing 737-8200 aircraft to the register between 3 October and 14 October. Air Astana registered EI-KDJ as an Airbus A321-271NX on 15 October. ASL Airlines Ireland Ltd registered EI-LKD as an Airbus A330-302 on 6 November after it operated as 2-JVDM.
The Irish Aviation Authority added EI-HPY as a Vulcanair P68-CTC to the register for a private individual. The authority registered EI-HRP as an Aeroprakt A22-L on 17 October for a private individual.
