Paid $16 for Wi-Fi on MUC-ORD a couple days ago and $32 on SFO-JFK today.

What's the reason for the higher price on the shorter route? Is it a P.S. thing? Or is it because I was in Business on the international flight and in Economy today?

Also, I could be imagining this, but I feel like the TATL Wi-Fi service was more stable and faster.
