The only 'common' airport that those two companies used that I knew of was Leeds/Bradford, from where I used them frequently.
Could fly to Glasgow, Edinborough, Bristol, Cardiff and Bournemouth very easily.
Danair had a 748 based at Leeds/Bradford that flew, Leeds - Glasgow - Leeds - Cardiff - Bristol - Bournemouth - Jersey - Bournemouth - Cardiff - Leeds - Glasgow - Leeds. Monday to Friday.
I could get the 1st leg to Glasgow, do a days work, and get the last leg home for an only slightly late dinner.
Happy Daze.
