I think you will find that Topend 4000 was a nonscheduled E110 flight AD to PLC for maintenance.
On the general thread Rex are creaming both ASA and GWA on the ADL - PLO route.
GWA while cheap lacks a decent schedule and ASA also has a schedule problem and does not seem yet to realise that customers down south expect on time departures. I predict that only one of these two will survive (most probably ASA) but they will have a long way to go to catch up with Rex, if they ever can, seeing ASA was run down badly by the previous owners.
