I'm not sure if this one qualifies or not, but here goes ...
In 2001 I was planning a trip to the USA, but 9/11 put a stop to all that. I looked around for something to replace that trip, and realised that I wanted 'beach' and 'sun' for a week. Quite by chance I watched a TV prog about India, and specifically Goa, so I started a lot of research into a trip there. A local travel agent got me assorted brochures, and very soon I was all booked-up ... Visa acquired, and injections booked.
At that time there was only one flight a week to Goa, which left Gatwick on a Thursday evening, and you arrived in Goa at about 7.30 local time on Friday. On the appointed Thursday evening I turned up at Gatwick, and we boarded an 'Air Travel' Airbus A.330.
It was a direct/non-stop flight, but quite soon after take-off they announced that there was some kind of glitch with the entertainment system, and that they might have to restart it all several times. I watched the start of the same film 4 times. We were mid way across Europe when they announced that they might divert into Bahrain to get the entertainment system fixed.
A few hours later they made another announcement that the system was working okay, and we would continue to Goa - in fact, out to the right, that is Bahrain!
So ... widebody, tick ... holiday jet, tick.
Immigration into Goa and baggage claim was the usual shambles!
The return leg one week later left Goa at about 12.00 local time, and we flew direct back to Gatwick. We arrived at the stroke of 8pm UK time. Taxy to stand, unload pax, walk to UK immigration, collect baggage and walk to the Green Line bus stop for the trip back to Heathrow, and the bus departed at 8.20pm! Pretty good going.
Two years later I did the trip again, but for 2 weeks. It still departed on a Thursday and got back on Friday evening. This time it was a Monarch A.310, with a refuelling stop at Bahrain in both directions.
