R Airlines (RCT, Bangkok Don Mueang) have tentatively suspended operations following the re-registration of its sole B737-400, HS-RCA (msn 25313), as N353AS in the United States. The 737 is understood to again be with Florida-based aircraft leasor, AerSale, having been parked in Bangkok Don Mueang for quite some time. Despite its ambitious start-up plans which included flights to Frankfurt International using a wet-leased B777-200, the airline has been barely visible since launching in September 2012.
