Thanks.
I'm traveling 24th May (A380), and was hoping to change it to 23rd May (A380)
The cheapest option is the 777 on 23rd May, though that departs at 0600. The next option is 20,000 Euro, which is business class
Given those options, I think I'll just leave it at the 24th May, and stay in the F suite!
