Saw the ASL TNT freighter coming in this morning which made me ponder the post-Brexit courier ops, since they operate domestically to & from East Midlands as tag-ons from their Continental bases:
ASL for TNT: EI- or OE-reg
Star Air for UPS: OY-reg
Swiftair for Fed Ex: EC-reg, based Belfast
Eurotrans for DHL: D-reg
West Atlantic for Royal Mail: SE-reg
