Purplehelmet...... that is what i meant when i said "what people vow and what people actually do are often two completely different things". People often vow never to fly with a particular airline but hey presto they usually do.
Consequently, out of those passengers who visit the UK on a regular/semi regular basis who "vowed never to fly into ringway again" the chances are most of them will. I know it wouldn't put me off flying into a certain airport. I absolutely hate passing through immigration in JFK, it's an absolute nightmare and takes an absolute age but next year I will travel there for the "umpteenth" time. It really doesn't bother me.
