Ok so me and my wife are going out in September and had plans to upgrade to Premium Economy. We have our seats assinged on the Virgin Atlantic website and we managed to get some of the ones at the back in blocks of 2. Now I don't know whether to upgrade or not. Things I'm trying to take into account are: - the allocated seats seem pretty decent but they aren't guaranteed - It is cheaper to upgrade at the airport but will there still be seats available on the day - we only really want to be in PE if we're in the bubble I don't think it would be worth it downstairs. Anyone have any opinions one way or another? Has anyone sat in the seats in blocks of 2 at the back?
