Hello, this is the first time i have to book an international flight for myself (i have always flown with family when i went to Usa). I was wondering if Virgin Atlantic flight's price changes from time to time, like it can happen with local and low cost company, or if I can buy a ticket now for 9 months later and the price will always be the same.
Another question: if I buy Economy now can I upgrade later to PE? Paying the difference or maybe less? And is it possible to get a bargain at the airport? Considering that I'll fly from London it can be harder to find one.
