Thomas Cook's website was the biggest travel site in the UK (in terms of traffic) from 1998-2002 (or thereabouts). This was despite a dismal site, lack of inventory and a general disregard from the management. At this time, Thomas Cook had the opportunity to look at Amex's missed chance in ruling the US online market and solidify its online lead in the UK. Instead it followed the well trodden offline dinosaurs strategy of being trapped in the headlights of the incoming online meteor shower. Another great BOOT mixed metaphor meaning that Thomas Cook stuffed up at the turn of the century in ignoring all of the advice and opportunity to establish UK online dominance. Now they have to play catch up by overpaying for a small provider.
