600 hellos and goodbyes.

I think I set a new record. Definitely for myself, and maybe for others too. Four flights to and from London Heathrow in under nine hours. I am wrecked after greeting and bidding adieu to that many people.

Of those of you that think that isn't a lot, you should try it. As the expression goes - don't knock it until you've tried it. It's fecking exhausting, especially at the end of five long, difficult days. Of course, that's not all I did for the nine hours - I completed other varied, strenuous and stressful tasks under extreme time constraints.

What wrecks you isn't the actual meeting and greeting - it's the ignorance and indifference that you encounter on every flight to Heathrow. They are a breed of passenger that really doesn't exist on any other flight.

Don't get me wrong - I love the variety of passenger that flies to Heathrow. You get the seasoned business traveller right through to the young Irish emigrant leaving for work and sunnier climes. You meet many people and cultures who have stories to tell - but what you remember in particular, are the idiots.

We seemed to encounter more than our fair share yesterday.

We initially thought it was one particular seat that was the problem. Seat 1D. But then we had one flight where no one was seated there, so that theory was quickly rubbished.

Was it the connecting flights that was putting our passengers under pressure? Nope - because we arrived on-time or ahead of schedule on all sectors.

Did we have supplies on board for all our passengers needs? Mostly.

Then, what irks them so? Was it the hangover London was feeling after the Olympics? Probably not.

There are always a bunch of people on Heathrow flights that look down their nose at you. They feel they have the right to patronise you. To demean you with a flick of their hair or dismissive glance. A look that displays their dissatisfaction at your very presence near them.

It's nothing to do with you at all - it's the company that you represent that makes them act like a proper plonker. Nothing they say or do makes any sense. They have no reason to treat you with such disrespect, but it happens on every Heathrow flight.

Then it hit me.

London was experiencing a mini heat-wave. With extreme levels of sweaty, sticky humidity.

The weather brought out even more eejits than normal - this week.
