Tracked tail histories like this show how charter fleets thread short repositioning hops and long transcontinental legs into a single continuous rotation.
The Bombardier Challenger 604 registered N135SM, operated by Solairus Aviation under flight number TWY308, flew nine recorded legs over an eight-day span from August 16 to August 23, 2026.

On August 16 the aircraft departed Port Hawkesbury (YPS) at 21:06 and landed at Bedford (BED) at 22:56, a flight of 1 hour 50 minutes. On August 17 it flew Bedford (BED) to Nantucket (ACK) in 26 minutes, departing 13:49 and landing 14:16, then continued Nantucket (ACK) to Van Nuys (VNY) in 5 hours 44 minutes, departing 15:34 and landing 21:18, followed by a 26-minute hop from Van Nuys (VNY) to Palm Springs (PSP), departing 22:13 and landing 22:39. On August 19 the aircraft flew Palm Springs (PSP) to Aurora (QSA) in 1 hour 53 minutes, departing 15:07 and landing 17:00, then [Aurora](/entities/43da0c309188558ebbd576bd83a2aeeb) (QSA) to Redmond (RDM) in 25 minutes, landing 18:38, before departing Redmond (RDM) at 19:29 for Danville (DAN), landing 23:39 after 4 hours 11 minutes.
On August 22 the aircraft departed Danville (DAN) at 22:53 and landed at Redmond (RDM) at 03:53, a flight of 4 hours 59 minutes. On August 23 it flew Redmond (RDM) to Aurora (QSA) in 26 minutes, departing 04:28 and landing 04:54.
This kind of tracked itinerary is typical of managed charter aircraft moving between coastal leisure markets and Pacific Northwest or interior stops without a fixed base pattern, stitching together short repositioning hops with long cross-country legs inside a single week.
In business charter, a single tail often serves several separate trip requests back to back, so a long westbound leg like Nantucket to Van Nuys can be followed within hours by short local repositioning to keep the aircraft near its next passenger pickup. The mix of 25-minute hops and five-hour transcontinental segments on one tail reflects how operators sequence utilization to minimize deadhead time between paying legs.
The next dated data point worth watching is whether N135SM's flight pattern settles into a recognizable base rotation around the Pacific Northwest stops it visited on August 19 and 22, or reverts to the East Coast routing seen earlier in the week.
