Ryanair has agreed an memorandum of understanding with Spanish energy group Repsol to purchase up to 52 million gallons of sustainable aviation fuel between 2025 and 2030. The agreement, which will bring the airline closer to its goal of powering 12.5% of its flights with SAF by 2030, is equivalent to over 28,000 flights from Dublin to Madrid, Ryanair says, saving 490,000t of carbon. SAF will be supplied to the carrier across Spain and Portugal. "SAF plays a key role in Ryanair's pathway to net zero strategy and our goal of using 12.5% SAF by 2030," says Ryanair DAC chief executive Eddie Wilson. "Achieving this requires multiple different feedstocks and production methods and we're encouraged that Repsol are looking at multiple solutions. This agreement helps Ryanair secure access to [circa] 15% of this ambitious goal."

Air Moldova has suspended flights and ticket sales as it awaits court approval of an "accelerated restructuring" plan, which the airline says is aimed at avoiding bankruptcy. The carrier says in a post on its Facebook page that it has submitted an application to the court for an "accelerated restructuring" plan that "aims to avoid the bankruptcy of the airline, solve the existing problems and accept investments". Air Moldova adds that unnamed investors are "ready to invest" $50 million in the airline, which it says would enable it to resolve its financial problems and renew its fleet. The airline has suspended flights from 2 May, noting that it aims to restart operations "within three days" of the court making a decision. Last month, Air Moldova said it had been "forced" to suspend all operations between 21 and 25 April, due to a lack of financial resources. It followed a warning from Moldova's civil aviation authority in November that the carrier was at "potential risk of insolvency". The regulator said at the time that an unannounced inspection had uncovered "serious deficiencies" in Air Moldova's finances, and that the airline had been asked to submit a corrective plan for approval. Fleets data shows that Air Moldova has a fleet of four aircraft, all of which are listed as being in storage. These include an Embraer 190 owned by the airline, an Airbus A321 leased from Willis Lease Finance, an A320 leased from TrueAero and an A319 leased from Carlyle Aviation Partners.

Global airline trade group IATA has disclosed that not all airlines will meet the US government's 1 July deadline to retrofit some of their aircraft with radio frequency filters that reduce the risk of 5G telecommunications interference. "Many airlines have indicated that despite their best efforts they will not meet the 1 July deadline owing to supply-chain issues," Nick Careen, IATA’s senior vice-president operations, safety and security, stated on 2 May. "This is only a temporary holding action. Under current scenarios, airlines will have to retrofit most of their aircraft twice in just five years. And with the standards for the second retrofit yet to be developed we could easily be facing the same supply-chain issues in 2028 that we are struggling with today." The US Federal Aviation Administration and the Department of Transportation in early 2022 expressed concerns that 5G implementation could interfere with radio altimeters on board aircraft. Under pressure from regulators, US telecommunications companies AT&T and Verizon agreed in January 2022 that their twin launch of 5G communications networks that month would temporarily bypass certain US airports amid ongoing safety concerns. US telecommunications companies subsequently agreed in June 2022 to keep their voluntary reductions of the power of 5G C-band signals near airports in place until 1 July 2023 to give the aviation industry an additional year to retrofit their airplanes with radio frequency filters. The FAA in an airworthiness directive (AD) published on 11 January 2023 proposed a rule that would set a February 2024 deadline for passenger and cargo aircraft in the USA to have 5G C-band-tolerant radio altimeters, or have installed an acceptable radio frequency filter. The proposed AD additionally requires carriers to revise their airplane flight manuals to prohibit low-visibility landings after 30 June 2023, unless the retrofits have been completed on that aircraft. IATA on 2 May noted that US telecommunications companies had recently extended until 1 January 2028 their voluntary mitigation measures for 5G C-band transmissions at 188 US airports, taking immediate pressure off airlines. The trade group adds that "while the agreement is a welcome stop-gap development, it is by no means a solution". IATA's Careen says: "Airlines did not create this situation. They are victims of poor government planning and co-ordination. Industry concerns about 5G, expressed for many years in the appropriate forums, were ignored and over-ridden."
