what will this trip cost?
Every plan here has a price read on the vendor's own page. Plans I couldn't confirm stay out, so the list can be short.
Buy through a link here and the vendor pays me a small commission. Your price stays the same. How that works.

When a trip outlasts a plan, the total is that plan bought again. That's my arithmetic, and vendors differ on top-ups, so read the terms before relying on it.
