I actually can't find any evidence that there ever existed a direct Anchorage-Belize trip. The parent comment implies that the company merely offered routes that extended to these destinations, but not necessarily as a single trip.
That is indeed what I was trying to imply. Although, as someone who grew up on the West Coast, I have to say that similarity in distance is still a bit surprising to me.
Across Eurasia. There might be some cultural/imagination thing going on. I have driven from British Columbia to Tijuana. I cannot even imagine how that would be across Eurasia.
