Sadly AM 4 wasn't an option with the BCN departure in their system. Something about no availability though there was plenty if you booked the legs separately. Instead I'm flying out on the AF flight 12 hours sooner. Shame that I won't get to be on the party bus to Mexico but now I'll get to experience AM, KLM, and AF business unless I spring for an affordable La Premiere upgrade.
It would have been cool to get a 15 hour layover in Paris. What are the chances of me being able to switch to AM 4 once I'm at CDG?
