Hi everyone. I just want to share my experience with you. We will fly on the 15th of Jan from VIE to LAX via CDG and back LAX - AMS - VIE on the 6th of Feb. We bought cheap economy tickets a few months ago. A few days ago I successfully bought a change of economy (L/V class) to business (Z) on way back from Los Angeles - LAX - AMS - VIE for cca 780€ per person which is pretty good price I think.
It wasn't able to do that on first segment (VIE - LAX) because first flight VIE - CDG is handled by Austrian Airlines, that's info I received from AF. But the thing is after this change my fiance got automatically upgrade to business from economy on segment CDG to LAX (AF0066), I see this change on air france website. I just want to ask if this is something common or not. We will fly with AF/KLM for first time. My ticket stays unchanged the same economy class from CDG to LAX so only her ticket has been upgraded. It's just weird situation (ofc I am happy for her change). Another question is when (even if) I can expect upgrade offer? Will I receive an email? Or should I refresh airfrance website? thank you
