Irish regional operator CityJet is seeking protection from creditors for the second time in five years. A petition to the Irish High Court to appoint an examiner, was filed by the airline on 8 May. An interim order was granted until a court hearing on 26 May. CityJet had entered examinership – a process in Irish law through which companies can protect themselves from creditors while they restructure – in April 2020 as the Covid-19 pandemic took hold. It exited that restructuring process in August 2020 as a smaller carrier focused on providing wet-lease services. Fleets data shows that CityJet has a fleet of three owned MHIRJ CRJ900 regional jets, which are listed as being in storage.

Communications and radar displays guiding Newark Liberty aviation traffic ceased to function for 90 seconds on 9 May, the US Federal Aviation Administration has reported. "There was a telecommunications outage that impacted communications and radar display at Philadelphia TRACON Area C, which guides aircraft in and out of Newark Liberty International airport airspace," the FAA notes, adding: "The outage occurred around 3:55am on Friday, May 9, and lasted approximately 90 seconds." United Airlines – which in May is set to operate 68% of all flights arriving at and departing Newark Liberty, says that it does not "have anything to share on the outage". The day before the radar outage at Newark, on 8 May, US Department of Transportation secretary Sean Duffy announced a plan to build a "brand new, state-of-the-art" air traffic control system for airspace in the USA. The announcement of the plan, which requires Congressional approval before going into effect, follows an equipment outage on 28 April at Newark Liberty that caused residual delays to flights. United chief executive Scott Kirby said in a 2 May message to customers, and shared on United's website, that "the technology issues [at Newark] were compounded as over 20% of the FAA controllers for EWR walked off the job". Kirby writes in an 9 May LinkedIn post that "the weeks of continued disruptions at Newark Liberty International airport has put America's air traffic control system in the spotlight and has revealed a broken system". He adds in the LinkedIn post: "Decades of failing to properly invest in the system has prevented good-faith efforts to make technology upgrades and bolster the staffing of our nation's hard-working air traffic controllers."
