Which airports could he have landed in?

To be clear; I'm not saying that the US pressure and European action were anything but petty. But you know; not all pettiness is equivalent to kidnapping a civilian plane.

Also, while I'm not willing to assume the best of intentions on the US's part; neither am I willing to assume them on Evo Morales's part. This grounding was in his interest - he had nothing to lose, and everything to gain. I doubt he tried to prevent the confrontation, and he may well have even taken actions to enhance the appearance of victimhood - it's always nice, playing a victim; especially if you're not actually suffering any harm.
