Airtours aeroplanes…?

In 2000, what type of plane would Airtours (which became MyTravel Airways, later integrated into Thomas Cook) have used from London Gatwick to Tenerife South Airport?
I remember it being a Boeing. Now at the time they were operating 6 757-200s and 3 767-300ERs, so which is more likely…? Does anybody know FOR SURE?

well I know that Airtours also opperated a variety of different aircraft, including Airbus and McDonald Douglasses. But if you are sure on it being a boeing, then it more than likely would have been a B757, as the B767s would have been used for more long haul routes to say the states.
