There has been around half a dozen of them, all equally enjoyable. Not because of the seat, the food, the service or - indeed - the aircraft. It was the simple joy of leaving the desert behind and knowing one is headed back to civilisation after being stuck in Knoteatingham for a month*
*I was offered a secondment to work in Knoteatingham for 12 months, and only accepted if they would book me a return home in J once a month. Since the company had an agreement with BA, that's the airline I was booked to fly on. Would depart the glitzy shytehole a.k.a. Middle East Prostitution Central on a Thursday evening and return the following Monday - a couple of extra days off a month was also part of the deal. That was the only way to maintain sanity.
As luck would have it, after around 6 months was asked to move over to Bahrain for the remainder of the secondment, which I gladly accepted. The monthly return flight deal was still on, but not nearly as vital for the mental health.
