I think BD
do some charters from Heathrow or MAN
to Volus and Skiathos. I remember seeing an BD
A321 in Corfu in August 2001. Virgin are currently flying A340-300 charters to San Juan on sundays from Gatwick.
do have seasonal charters.
A lot of them from Gatwick are BA9***C to Ibiza, Mahon, Innsbruck, Chambery etc.
