planning for a week of Paris and London in 2026

I always have the urge of going to Europe, especially so to Paris, although a direct flight from LA to Paris is 10+ hrs nonstop, I would still do it in a plunge.

my friend and I started planning in November 2025 (kinda last minute with many moving pieces), we flew in separately and landed at CDG 1 hr apart.

we decided to spend 4 full days in Paris, and we would part ways where I would head over to London and he to Barcelona.
