The EasyJet punctuality figures (taken from their website for Nov 2002) are arrivals 80% within 15 minutes of advertised, and 93% within 1 hour. Seeing as that was for a month when we have had some bad fog days over here, that's as good as I would expect the figures to be able to get to.
Poor Rosebud9802 who started this post off must be really confused with all the "facts" offered above which we Brits are having to continually correct! Let's strive for more accuracy.
