I think you mean the one I wrote about 9 or 10 years ago? It's still available from within the Wannabes - Interviews and Jobs forum. However, it probably needs updating!
Virgin still operates to 750 hours, though there is a 10 hour 'buffer' to allow a pilot to hit 750 during a trip and not have to stop short at, say, 730. Our pay is at least in part tied to flying hours, so lost time is expensive. While annual overtime (ie over 760 hours) is potentially available, in times of difficult employment and with many of our Virgin colleagues still waiting to come back after being furloughed, it is perhaps unfair to fly hours that should be being flown by a another pilot who is currently laid off...
A typical roster at Virgin (on the A340) will include four or five longhaul flights and around 80 flying hours. Each trip will be between 3 and 9 days away from home. Time off will normally be in blocks of two or three days but occasionally may be longer. The minimum time off (at home) in a month is 10 days. Ground training (simulator, safety equipment, avmed, tech refresher etc) is rostered at varying intervals and usually effectively replaces a trip in the roster. Standby is rostered in month-long blocks and typically comes round once a year, though it can be more or less frequent. There are no guaranteed days off during standby, but industrial agreements ensure that you will get more or less the normal number of days off, though you won't know when you'll get them!
Rosters on the B744 are different in that the Boeing tends to operate shorter flights, so you could occasionally get 6 flights in a month. Equally, because of the tortured and complex system of schedules we have to the Caribbean, you may well do a considerable amount of positioning on flights which earn few flying hours yet keep you away from home for up to six days. This is an issue which is hopefully being addressed, but seems somewhat intractable.
Longhaul flying is not about the aeroplane. There is nothing intrinsically better about flying an A340-600 or B747-400 than a Dash or an Embraer. The job at the beginning or end of each flight is much the same, but the bit in between is very, very much longer. If you can't abide sitting more or less still and doing little or nothing for 10 hours or more, don't apply. When you get to your destination, it is likely to be a lot less interesting and stimulating than you might have anticipated (though not always), and it will be a very long way from home. If your other half has difficulty with independence and self-sufficiency, do not apply. The parties and jollity that you may have read or heard about at Virgin are very much in the past. That's not to say that there is no fun to be had down route, but it will be up to you to provide it. If you were expecting lots of alcohol, sex and stories to tell your grandchildren, don't apply! Your time at home will be compromised hugely by fatigue. In a typical two-day stopover at home, you will sleep for a lot of it, feel crap for most of it, and be expected to do all the stuff which has stacked up while you were away enjoying yourself. Your relationship needs to be very strong, and your domestic support network must be fully functional and able to swing into action whenever you are delayed away or a crisis hits at home.
While I don't want to give the impression that longhaul is harder than lo-cost or any other form of flying, it brings challenges that you might not expect and may be ill-equipped to deal with. Professionally, it's very different to short-haul and relies hugely on self-study and prior experience replacing hands-on practise. You can't learn to fly in this job! Personally, it puts huge strains on you and yours and the change from whatever you're comfortable (or at least coping) with right now may be too much if you don't anticipate the problems and put in strategies to counter them.
I wish you all good luck.
