I'm also going to experience my first first in April. Also to LAX on the A380. I can't wait.
Intending to have a great brekkie in the concord room. Enjoy as much champagne on board as possible, but not too much that I pass out and forget the experience. I will be partaking in the new tasting menu, putting on my A380 first pajamas, even though it's a day time flight and then stuffing my face on afternoon tea. I might even play with the window blinds for far too long. I will definitely eat too many scones for afternoon tea.
What's your plan?
