Canadian carrier WestJet issued a request for proposals (RFP) at the start of June to sell the Boeing 737-700s that it owns. The deal comprises 27 aircraft, and WestJet is interested in leasing back 17 jets, a source says. They add that the deal is structured in three tranches. Back in April, it was reported that lessors were expecting WestJet to issue an RFP for up to 29 737-700s, possibly in June. The RFP had been in discussions since early last year. WestJet has an in-service and stored fleet of 35 737-700s, Fleets data shows. The aircraft range in age from 15 years to 23 years. The eight aircraft it doesn't own are managed by lessors including Aero Capital Solutions, BBAM, Castlelake, Deucalion Aviation, IAT Leasing, ORIX Aviation and SMBC Aviation Capital. All those lessors manage one unit apiece, except Deucalion, which manages two units.

The UK government is investing £219 million ($294 million) to accelerate development of the country's SAF industry. Disclosed on 16 June, the initiative includes £93 million over the next two years for companies developing SAF projects. Applications will open in mid-July. The funding is part of a broader low-carbon fuels fund set to launch later this summer. The Department for Transport (DfT) says the programme will help to establish the UK as a global hub for SAF production, contributing £5 billion to the country's economy by 2050, and builds on £198 million already committed through the Advanced Fuels Fund since 2022. Alongside the announcement, the government has launched a call for evidence on the UK's SAF mandate. This stipulates that SAF's share of fuel uplifted must rise from 2% last year to 10% in 2030 and 22% by 2040. The consultation is intended to ensure the policy framework "remains responsive to an evolving market", the DfT says.

Asiana Airlines has exercised conversion rights on bonds issued by Air Busan that have increased its stake in the low-cost carrier to 58.4% as it plans to merge it with two other low-cost carriers during the first quarter of 2027. The company, which is now a subsidiary of Korean Air, announced the transaction in a 15 June stock exchange filing that shows the nominal cost of the transaction was W100 billion ($66 million). Asiana acquired the unguaranteed perpetual private convertible bonds in May 2025, with maturity in 2055. The bonds were subject to a 12-month period where they could not be converted. Prior to the conversion, Asiana held a 41.9% stake in Air Busan, with the remainder held by the Busan City government and other institutional investors. The airline operates a fleet of 21 Airbus A320 family aircraft, comprised of eight A321neos, eight A321ceos and five A320ceos, Cirium fleets data shows. Earlier on 2 June, Air Busan confirmed in a separate statement that it is working with two other Korean Air Group-affiliated low-cost carriers – Air Seoul and Jin Air – on a plan to merge and create a single airline. "We are currently reviewing detailed matters regarding the launch of the integrated LCC, including specific merger methods, ratios, and schedules. We plan to proceed with the goal of launching the integrated LCC within the first quarter of 2027, in conjunction with the parent company’s merger schedule," Air Busan states. Air Seoul, which is an Asiana subsidiary, operates six A321ceos, while Jin Air operates 33 Boeing jets, comprised of 19 737-800s, three -900s, seven Max 8s and four 777-200ERs.
