I'm sure the 13 hour rule is on their website, but I spent very little time on their website after learning I couldn't use it to view / change / do anything with my reservation.
The four of us were in economy class.
And figures we ended up getting one of the last remaining old A340s. Seems odd to me Virgin would choose to place an old plane on a new route (back to my first impressions comment). I would suspect most(?) customers on this route are new to Virgin, and therefore wouldn't you want to put your best foot forward to impress all these new customers in hopes of gaining their loyalty?
