Virgin also at this stage don't offer lounge access for International Departures, just take that into account. Something Virgin does well is they rope off the Biz Cabin, so the Biz cabin has private use with the front bathroom. The return leg will likely be a red-eye just take that into account as the seats are recliners not flat, however you won't be disturbed by a hundred plus economy passengers hanging around for the bathroom. Check the offers also before you book, I got an email this week for double points, that would add up especially if flying long haul.
