They did in summer 1994 routing KEF-GLA-MAN 2 weekly I think...they said they were happy with the performance. Yet, it wasn't until 2001 before starting up again in this manner:
charter service: February to early June
scheduled service: early June to Septemberish
charter service; Septemberish to November.
Timings were the same: arrive midday Friday, depart 02.30 on Sundays, and normally with the same 757: TF-FIW, which often flew for other airlines whilst it was here.
